DX T I appreciate it brother- I try to keep it somewhat objective and date I say “scientific” around here.... Nathen is just a bully you know? Lol. Thanks for commenting!
Honestly it’s worth it if you enjoy the things you added and it doesn’t hurt you financially, I’d say if it was my grom I’d love to sit there and work on it I’d be excited to put the expensive part in there even if it does 6-7 more mph it would make me happy idk about you
Well said. You get it. Not everyone does with these groms and that's ok you know? Everyone is different but you definitely nailed it. Modding them becomes so addicting, then hopping on the bike for the first time with that new mod and feeling the difference albeit small, its so satisfying!
CT Gromer I didn’t think you would reply, I personally don’t have a grom but My friend does I’ve ridden his I’m currently trying to save up for one keep making videos they rock!
@@robert-zh2gl I always reply! Keep saving up and let me know when you get one! I have another video dropping soon I'm currently editing- 2 year review of the grom! Make sure you watch out for it!
Watching your speed and the RPMs I am seeing that the z125 is geared a lot higher! I am shifting out of 3rd into 4th at like 45 mph and you are able to wind out second gear to like 42 or something. Very interesting indeed!
I'm geared stock from the factory on my grom (the black one). But I'm not afraid to really wind it out when I'm going for speed. The re-flashed ECU on the bike allows to to rev to 10,500RPM before the limiter stops me. Thanks for commenting!
@@CTGromer and is that okay? I too was closely watching how you winded it out lol. So is the flashing just to get around that limiter and only helps if you wind it out like that? And is it okay to do that? Thanks for the video man!
I really appreciate the compliment on the channel music, I work hard to find songs and music that viewers will like. Thank you for commenting, I hope you keep watching!
I'm 5'10", 180lbs, and my stock 2018 usually runs about 53mph according to the speedo. I've hit 57 going down a hill. It's only got 70 miles on it, so I'm hoping as it breaks in it might gain a little.
It definitely will! I’ve owned two with only a couple hundred miles when I bought them and both got a little faster by the first 1,000 miles. So do not fret! Thanks for commenting!
DMXRACR looking back at the footage I see what you mean, the position of the cross pad on the after market bike makes me have to tuck differently then the stock open bars. I don’t think I actually got any lower. If I did, it’s negligible, and doesn’t change the important number which to me is the 10-55mph time. Definitely see your point though, thanks for commenting!
@@CTGromer Thank you for replying! I just looked aty the video again and you are TOTALLY correct! Thank you for bringing it to my attention. I appreciate your accord. I do ENJOY your videos and hope you keep them coming. I watch them because I appreciate them and your efforts that go into them with cameras, editing and the information you are providing! Thank you!

The DHM Reflash with the TB Cam made the Power Commander 5 module redundant, correct? So much fun to cruise on and race these suckers! X)) Cheers, be well!
That's correct, using both would be redundant. I no longer use my Power Commander 5 Module and have replaced it permanently with the DHM Reflashed ECU. Aren't they the best??? It was 104 degrees when we shot this and we were still having a ball! Thanks for commenting!
great vid. I have noticed with mine that running the valve tappets at .003 intake and exhaust instead of .004 and .007 that tb cam recommends got me a bit more power.
Not sure if you're serious but you'll regret it!!!! I started at the top and ended up with a grom. Had a ZX10R, KTM supermoto, harley, R6 and all that's left in my garage is some dirt bikes and a grom lol. Grom is the most fun I've had on any of those bikes. The supermoto came close, but was too big to do the dumb things I do on the grom. I also seemed to attract cops on the supermoto because it looked like a badass MX bike and sounded like a monster trapped in a cave. I couldn't go off roading without cops from the next town coming to check it out. My grom has a stock exhaust on purpose now so that I can do stupid stuff without getting the stink eye from people. I ride a wheelie and people just laugh at me lol
I appreciate it! It's very unique looking and night and day more comfortable than the stock seat. They're hard to find now, it's called a MAD gel seat.
Hey man, for a fairer and more accurate test. You should've checked the tire pressures of both bikes and see if they're identical. But otherwise awesome grom content.
Cholo Mojica you’re right. I’m always running 30psi- but I did not check the stock bike. That definitely makes a difference in these little low horsepower bikes! Good advice- thanks for commenting!
MPG difference is minimal, I honestly haven't noticed a significant drop. reliability- still hasn't broke down on me yet. Just checked the valves again after 2,000 miles with the new CAM - still in spec :)
@@CTGromer That's awesome, I've heard with certain cams, the valve adjustment had to be tightened down pretty much all the way, did yours begin to run out of adjustment? The reason I ask is, if the valves naturally get loose down the road they won't have any more room to tighten back up.
Hi CT Gromer what did you think about changing the OEM Wheelbearings to Hybrid ceramic bearings and aluminum spacers instead of the original? Would it make the Grom faster? Thanks in advance for you answer
If you can justify the price, I think they would absolutely make the grom faster. The grom only has 8-10 horsepower depending on your mods, so things like body weight, tire pressure, body position matter a lot. Reducing friction to allow the wheels to spin easier will definitely make the grom faster. How much faster? Who knows, but it can only help.
Thanks for your answer ct gromer I will do it on my Grom I also had tb cam from Dhmotoring and I love it I also think that the bearing change will be helpful and bring the power better to the wheels
Just curious about those 180cc kits for the Grom. Are they reliable ? I was thinking about getting one because I’m tall and heavy but I love small bikes. Thanks man great video btw.
I've seen good 181CC kits that yield a lot more power, but thats a pretty big bore. I'd stay stock bore as long as you ca if your concern is long life and reliability. the 181s run very hot and if you have a lean condition at all, you'll overheat it pretty quickly. Not to mention the added stress on the bottom end from a much larger piston. Just my $0.02.
CT Gromer thank you! Yes I think based on watching your videos that a Chimera Air intake and an exhaust may be the best thing as I want to keep it fully reliable. Great content btw! 🙌🏻
looking into getting a grom! do you think new is the way to go? the used ones are only 200-300 dollars cheaper but that’s a whole payment on my car for a month, and money is tight rn lmao
I would honestly wait around for a deal and try to grab one for $2,500 - $2,700. plenty of them out there, you just have to be patient and look every day. Have the money ready so you can strike quick and get the deal! Thanks for commenting!
were the speedometers calibrated first? in my experience some new and used motorcycles, especially some, not all, around 250cc and less from a regular dealership are set about 8-15 mph faster than the actual speed limit. I guess they think if it's a small cc one and the speed is faster they sell better.
They're not calibrated, no. However, I can guarantee they're not 8-15mph off. Maybe 1-2 miles off. I've driven beside my wife many times and asked her what her car speedo is reading and its always been close to the grom. Thanks for commenting!
Personally I am happy with my grom as it is , Its not meant to be a fast bike and I'm sure messing with the motor like that will certainly effect the reliability and life of the motor , But each to there own
Planning on buying one, in going to keep the stock exaust on it, I prefer a quiet bike while I'll be doing little adventures in places I shouldn't be. In terms of performance I'm going to keep it mostly stock & maybe just install only minor functional mods. The extra 5 miles per hour isn't worth an extra $1,200. I'll get a bigger bike if I wanna go fast. A top speed of 63 is enough for county roads.
That's your prerogative man, I thought I would keep mine stock too... Good on you if you do, I've been in many situations where I wish my exhaust was quieter, that's a great point. Thanks for commenting, hope you end up getting one!
I have a similar setup but with a Dinger 34mm and ported TB+manifold. Did the TB cam as well. I also did the Mini5 Aracer. My bike seems about as fast as yours but I'm running knobies so I'd assume I'm only slightly faster with street tires. If I didn't have big bore plans I would have probably done what you did as money wise it makes sense.
Dude that’s some serious commitment! I bet it moves! No doubt you’d be faster with some power pures! Let me know what happens when you big bore! Thanks for commenting!
@@CTGromer If I don't I'll probably go 4v Koso. I think I'm gonna go 5 speed first before I go BBK unless I find a cheap new kit somebody never put in in the meantime. I just got so many other vehicals I'm putting money into and it kills me.
@@Ty5oN101 Oh yeah, I hear that. Once you start modding stuff, these machine grow arms and turn you upside-down and shake you out like a piggy bank every time you go in the garage! They're so entitled you know!?? lol.
Have you tried a 1 tooth down front sprocket ? I saw a nice video on this mod ($10.00), seems at that price little to lose. I installed a booster plug on my Harley. It’s a fuel controller seems to work well. I need more riding time. This may be all a Grom may need for a stage 1 upgrade.
Take a riding class dude. You went by those 2 cars at the stop sign on the right waiting for you to go buy in RIGHT lane and didn't even slow down taking it for granted they weren't going to turn in front of you? You should've been in the left lane and slowed down as it gives you more time to react.
Another solid video with great visual comparison of speed. The stock grom looks stuck in the mud compared to your mod bike. What do you think, should I get a grom?
Bro, you have some quality content, and it doesn't seem to be too clickbaity. I subscribed. I got a stock '19 Grom a couple months ago. Do you think it would be worth it if I re-flashed the ECU only, and left the stock exhaust? I've been looking at the Cam/Piston/ECU flash package from DHM, but I didn't realize an aftermarket exhaust is recommended. I like stock exhaust because it's quiet. I wouldn't mind making other mods because it doesn't affect noise and fuel efficiency (to a certain point--until the revs hit higher because of the ECU flash, from my understanding.) Or maybe I should just suck it up and get a loud exhaust.
What's up dude, I really appreciate the sub and the compliment on the channel! I try to keep the content information dense and not too much advertising. I will actually be reviewing the DHM stage 3 kit with high comp stock bore piston as my next video! I'll also be doing speed comparisons between stock grom, DHM stage 2 and DHM stage 3. I know what you mean about having quiet exhaust. I wear earplugs with my yoshi. It's loud. However, it gives me the most power. If more air is going in, you have to maximize the tune by having more air go out. The best options for you would be to get a Zoom exhaust. They're affordable, and they're relatively quiet if you keep the baffle in them, especially compared to the AR exhaust found on Amazon or the yoshi. Actually, the Amazon grom exhaust is pretty quiet too!
Oh nice, I'll be sure to watch your next vid! From my amateur research, ECU/cam/piston (plus intake/exhaust) seem to be the best bang for the buck--only downside for me being a loud exhaust and requiring higher-octane gas. Plus the extra $$, haha. That makes sense; I think I'll just bite the bullet and pick up an exhaust then. Still under warranty, so I'll probably wait 'til that's up. Thanks for the reply!
Is there Any exhaust that is a Little bit cheaper than THE yosimura exhaust Looking for a exhaust that makes power and a great sound bit i cant afford THE yosimura exhaust
YES. I've tested all sorts of different grom exhausts, and I can tell you without a doubt, the Yoshi makes more power than any of the ones I've tested. You definitely get what you pay for in that department.
I will soon see what mi e will do stock. And we are using 95 octane fuel here. What did you use? Would be nice to hear what influence of 91 or 95 octane does. It is something most viewers don't realise.
I wish we had 95. I run 91 in mine; but I have stock bore and stock piston, so I think i'm just paying a little extra for nothing. All my toys get the higher octane fuel.
@@CTGromer It was merely a reminder for international viewers. And will make a difference for sure. Honda ECU will normally self adapt. But only within a certain range of octane. I know this as my Buell XB12-Scg also runs a K&N filter, open exhaust and re-programmed ECU. People easily copy within forums without ever mentioning type of fuel.
Everybody's Grom is a little different, I've said this before, because I small differences in manufacturing, I truly believe just like the silicone lottery with computer processors, you get some groms that are faster than others from factory. Enjoy!
Do you think I can get the same speeds with a Chimera intake, yoshimura exhaust, and a power commander? Would I need to install anything else to make it more reliable?
@@CTGromer Appreciate the response. Ended up watching more of your videos and went with yoshimura, chimera intake, 14t sprocket, DHM ecu flash and cam. Any other recommendations for top speed?
@@Tarzan2922 Nope that will do it! Thats the best you'll get out of your grom without going BBK, which I'm against because you use your reliability that the grom is legendary for.
Yes, I tucked on both bikes, I have to tuck differently on each bike because of the cross member on the protapers that is not present on the stock bars. Thanks for watching!
I wonder how much proper fairing would help. Looks like it was only minimal 7mph difference. Looks like you were tucked in closer on the modded grom. Same helmet same camera right? A little cheat for the modded grom.
7mph difference roughly, yes. But it got there significantly faster on the modded grom. The tucking was brought up once before, because there is a cross member and pad on the modded grom, I had to tuck differently than on the open handlebar design on the stock grom. All good points though.
Is the popping just the wind? I bought a used grom and it starts popping at 55mph. Didn’t do it at first. I think it’s the valves but I’ve never done valve adjustment so I’m hesitant to try. And I can’t find anyone to do it for me. Also can’t find anyone to weld an o2 bung for my wideband I bought.
Yes, the popping is just the wind, and my microphone malfunctioning. My grom does not pop at all, even on deceleration. It sounds to me like you have a lean condition- get the o2 bung hooked up ASAP, and adjust those valves! It's not hard - I cover it in my latest video actually: ruclips.net/video/zbNngFAu3J8/видео.html Skip to 8:25 for valves. Good luck!
CT Gromer thanks man. I appreciate the advice and link. The bike was dyno tuned with the power commander V. So I think it’s just the valves. But I am excited to see what the wideband does. It auto tunes to specified AFR at all throttle position as opposed to the Power commander that is only at 80% and up. Should be a good upgrade with all the others already done
I tucked in both speed runs, just had to tuck differently because the bars are different on both bikes. The modded bike has a cross-member that I had to tuck behind, whereas the stock grom I can tuck my head between the bars which are open with no cross-member. Can definitely see how this would cause confusion though.
I'm 6'2" about 235 and I got 62 out of my grom on flat. Only thing that's different is the previous guy put some cheap chinese pipe that I have no idea what it is
@@CTGromer I just tuck down as far as I can haha. I wanna do some power mods though, just so I can hang a little easier with a couple dudes I ride with
@@CTGromer first thing I'm gonna throw on is that intake. It really seemed to make a big difference for you. I know it gets good miles per gallon regardless, but do you notice a considerable difference with a cam and a tuner in terms of fuel usage?
@@seang.4533 Yes, you'll really notice the intake, and it'll will run safer when you re-flash ECu to richen the air/fuel mixture. Honestly, I didn't notice a significant drop in fuel economy.
Wtf?! My bike was 125 before I started modding (cg titan 125 from 99's Brazilian market). I spend less than 1100 dollars on it between the purchase and the mods and it goes over 100mph. Where the hell is all that cash going?
Comparing those two engines sounds like we are comparing apples to oranges, I'm not too familiar with the engine you're referring to, but I would challenge its reliability against the tried and true Japanese grom engine in a heartbeat, thanks for commenting!
@@CTGromer the grom never made it to Brazil, the only 125cc's honda released down here were the cg "titan" and the cg "fan". They both are not quite as reliable as a super cub (also never made it to our market) but you can find real cheap parts and mods. P.S. mine has over 70000km ( about 45000 miles) and the only problems I had with it was clogged carburator and gas filter due to dirty brazilian gas and riding without an air filter.
@@CTGromer in Brazil alone over 7 milion of those were sold, it's the standart bike for milions of pizza and what-not delivery guys! Btw, you got one subscriber!
when you hit 60 and then had another gear to go on the modded grom i was very impressed
She's quick for just a grom! Stock bore too!
10-55 in 15 seconds is hilariously slow, but looks like a blast on a Grom.
It really is, and yes, it really is!
My lil bitty 70cc scooter would really hurt some modded Grom feelings lol
Because it really needs like 9 gears to actually have a good enough overdrive gear to cruise with.

looking into getting a grom! do you think new is the way to go? the used ones are only 200-300 dollars cheaper but that’s a whole payment on my car for a month, and money is tight rn lmao
I would honestly wait around for a deal and try to grab one for $2,500 - $2,700. plenty of them out there, you just have to be patient and look every day. Have the money ready so you can strike quick and get the deal! Thanks for commenting!
What if you tuck?
Lit Brit Great question, I should clarify: I tucked in all of the speed runs. Thanks for commenting!
were the speedometers calibrated first? in my experience some new and used motorcycles, especially some, not all, around 250cc and less from a regular dealership are set about 8-15 mph faster than the actual speed limit. I guess they think if it's a small cc one and the speed is faster they sell better.
They're not calibrated, no. However, I can guarantee they're not 8-15mph off. Maybe 1-2 miles off. I've driven beside my wife many times and asked her what her car speedo is reading and its always been close to the grom. Thanks for commenting!
Dope content!! 👍👍
Very much appreciate the kind words, and I'm glad you're enjoying the channel!
Good video
Glad you enjoyed, thank you for taking the time to watch and comment!
Honestly didnt like the video until the last 2 minutes but that got you a like 😂😂😂
Fallensaleen02 lol! Well I’m glad I was able to barely squeak it out at the end! Thanks for watching, commenting and liking!
Yes but is the modded Groms speedo calibrated.
Both of these groms had stock gearing, and stock speedos so the comparison should be valid in that regard.
Personally I am happy with my grom as it is , Its not meant to be a fast bike and I'm sure messing with the motor like that will certainly effect the reliability and life of the motor , But each to there own
You're probably right to some degree it will effect reliability. Thats why I stay away from big bore and things of that nature. Thanks for commenting.
Planning on buying one, in going to keep the stock exaust on it, I prefer a quiet bike while I'll be doing little adventures in places I shouldn't be. In terms of performance I'm going to keep it mostly stock & maybe just install only minor functional mods. The extra 5 miles per hour isn't worth an extra $1,200. I'll get a bigger bike if I wanna go fast. A top speed of 63 is enough for county roads.
That's your prerogative man, I thought I would keep mine stock too... Good on you if you do, I've been in many situations where I wish my exhaust was quieter, that's a great point. Thanks for commenting, hope you end up getting one!
I have a similar setup but with a Dinger 34mm and ported TB+manifold. Did the TB cam as well. I also did the Mini5 Aracer. My bike seems about as fast as yours but I'm running knobies so I'd assume I'm only slightly faster with street tires. If I didn't have big bore plans I would have probably done what you did as money wise it makes sense.
Dude that’s some serious commitment! I bet it moves! No doubt you’d be faster with some power pures! Let me know what happens when you big bore! Thanks for commenting!
@@CTGromer yeah totally man I've done every other supporting mod to go big bore and even the clutch cover. I really want the Neo kit.
@@Ty5oN101 The neo is the best I think too, only $997 though! lol! Let me know if you do it!
@@CTGromer If I don't I'll probably go 4v Koso. I think I'm gonna go 5 speed first before I go BBK unless I find a cheap new kit somebody never put in in the meantime. I just got so many other vehicals I'm putting money into and it kills me.
@@Ty5oN101 Oh yeah, I hear that. Once you start modding stuff, these machine grow arms and turn you upside-down and shake you out like a piggy bank every time you go in the garage! They're so entitled you know!?? lol.
Have you tried a 1 tooth down front sprocket ? I saw a nice video on this mod ($10.00), seems at that price little to lose. I installed a booster plug on my Harley. It’s a fuel controller seems to work well. I need more riding time. This may be all a Grom may need for a stage 1 upgrade.
I have, I actually just did the install and will be dropping a video soon in conjunction with upgraded clutch springs! Keeping watching!
Please same video but compare the tnt135 benelli vs grom.. thanks..
Take a riding class dude. You went by those 2 cars at the stop sign on the right waiting for you to go buy in RIGHT lane and didn't even slow down taking it for granted they weren't going to turn in front of you? You should've been in the left lane and slowed down as it gives you more time to react.
Another solid video with great visual comparison of speed. The stock grom looks stuck in the mud compared to your mod bike. What do you think, should I get a grom?
Dustin Ilic thanks Dusty!!! In my opinion, finding a quality used Grom to purchase and improve your life and mine should be your top priority.
Bro, you have some quality content, and it doesn't seem to be too clickbaity. I subscribed.
I got a stock '19 Grom a couple months ago. Do you think it would be worth it if I re-flashed the ECU only, and left the stock exhaust? I've been looking at the Cam/Piston/ECU flash package from DHM, but I didn't realize an aftermarket exhaust is recommended. I like stock exhaust because it's quiet. I wouldn't mind making other mods because it doesn't affect noise and fuel efficiency (to a certain point--until the revs hit higher because of the ECU flash, from my understanding.) Or maybe I should just suck it up and get a loud exhaust.
What's up dude, I really appreciate the sub and the compliment on the channel! I try to keep the content information dense and not too much advertising. I will actually be reviewing the DHM stage 3 kit with high comp stock bore piston as my next video! I'll also be doing speed comparisons between stock grom, DHM stage 2 and DHM stage 3. I know what you mean about having quiet exhaust. I wear earplugs with my yoshi. It's loud. However, it gives me the most power. If more air is going in, you have to maximize the tune by having more air go out. The best options for you would be to get a Zoom exhaust. They're affordable, and they're relatively quiet if you keep the baffle in them, especially compared to the AR exhaust found on Amazon or the yoshi. Actually, the Amazon grom exhaust is pretty quiet too!
Oh nice, I'll be sure to watch your next vid! From my amateur research, ECU/cam/piston (plus intake/exhaust) seem to be the best bang for the buck--only downside for me being a loud exhaust and requiring higher-octane gas. Plus the extra $$, haha.
That makes sense; I think I'll just bite the bullet and pick up an exhaust then. Still under warranty, so I'll probably wait 'til that's up.
Thanks for the reply!
I got 71mph on a stock grom (MSX125 SF 2019)
That's insane! How much do you weigh!?
@@CTGromer Like 12 Stone ish, I actually got it to 74 but that was down a small hill. But yh around 69-71 on a flat.
@@ChrisHealen ok, thats wild! 12 stones is approximately 168 lbs, which is just a hair heavier than me. Stock grom 71 MPH is awesome.
How!? I have a 2019 as well and my max speed is 68 down hill with the wind behind me! Weigh about 150, so thats crazy!
@@YZ2502fast Dont get me wrong when it gets to about 68 -70 ish it sounds like its dying so I dont really do it.
Good shit
Thanks for saying so!
Is there Any exhaust that is a Little bit cheaper than THE yosimura exhaust
Looking for a exhaust that makes power and a great sound bit i cant afford THE yosimura exhaust
Definitely. I always promote the Zoom Looped exhaust, decent quality and half the cost of the Yoshi. Give that one a look.
@@CTGromer does it gives that extra power also?
@@pegganstunt8985 it does!
@@CTGromer okey thanks
Bore up kit from koso please 180cc with bells and whistles for head cylinder set up.
I don't know what the future holds, I'm going to stay 125cc's for now. But who knows down the road, thanks for commenting!
A little cringey at the end but thank you guys 😂
sometimes a little cringe goes a long way for its entertainment value
Does THE exhaust have a difference of increase horsepower forexample yushimura vs ransoto
YES. I've tested all sorts of different grom exhausts, and I can tell you without a doubt, the Yoshi makes more power than any of the ones I've tested. You definitely get what you pay for in that department.
@@CTGromer ok thanks
@@CTGromer what is THE second best exhaust for a Little cheaper Price?
Do you think it’s possible to make a turbo work on a 2020 Honda Grom?
Its definitely possible, I've seen two turbo'd groms. They're not that effective, but definitely a novelty.
and how much more gas does the modded consumes?
I will soon see what mi e will do stock. And we are using 95 octane fuel here. What did you use? Would be nice to hear what influence of 91 or 95 octane does. It is something most viewers don't realise.
Even fuel octane can't be trusted though. See this nice report; www.eea.europa.eu/publications/fuel-quality-in-the-eu
I wish we had 95. I run 91 in mine; but I have stock bore and stock piston, so I think i'm just paying a little extra for nothing. All my toys get the higher octane fuel.
@@CTGromer It was merely a reminder for international viewers. And will make a difference for sure. Honda ECU will normally self adapt. But only within a certain range of octane. I know this as my Buell XB12-Scg also runs a K&N filter, open exhaust and re-programmed ECU. People easily copy within forums without ever mentioning type of fuel.
@@henriwolbrink I find my z125 runs better on 87. Tried 91 and higher see no difference.
I want a grom sooooo bad
Get you one bud! Let me know if you do!
I can't I don't got the cash
With all that mode still alittle slower than my stock grom made in Thailand top speed of 121km/74mile
Everybody's Grom is a little different, I've said this before, because I small differences in manufacturing, I truly believe just like the silicone lottery with computer processors, you get some groms that are faster than others from factory. Enjoy!
@@CTGromer true sir...btw keep up the good work!! Loving all this grom vid
@@hyperzgrom9775 Thanks a lot for the support! I'll keep the content coming!
Do you think I can get the same speeds with a Chimera intake, yoshimura exhaust, and a power commander? Would I need to install anything else to make it more reliable?
Depending on how much you weigh, I think you could get close. The only thing that will make more of a difference is the cam, which I recommend.
@@CTGromer Appreciate the response. Ended up watching more of your videos and went with yoshimura, chimera intake, 14t sprocket, DHM ecu flash and cam. Any other recommendations for top speed?
@@Tarzan2922 Nope that will do it! Thats the best you'll get out of your grom without going BBK, which I'm against because you use your reliability that the grom is legendary for.
@@CTGromer thanks man! Keep up the good work!
I’ll never sell my grom, they’re so much fun.✊️😆
Did you have to tuck on the stock Honda grom to reach the 62mph?
Yes, I tucked on both bikes, I have to tuck differently on each bike because of the cross member on the protapers that is not present on the stock bars. Thanks for watching!
CT Gromer for someone new to riding would you suggest getting a grom with or without Abs on it ?
@@ajalamcgregor9354 depends on what you want to do... stunt = no abs ride = yes with abs
I wonder how much proper fairing would help. Looks like it was only minimal 7mph difference. Looks like you were tucked in closer on the modded grom. Same helmet same camera right? A little cheat for the modded grom.
7mph difference roughly, yes. But it got there significantly faster on the modded grom. The tucking was brought up once before, because there is a cross member and pad on the modded grom, I had to tuck differently than on the open handlebar design on the stock grom. All good points though.
Yes see I like that kid race the bikes
Nathen knows what's up for sure. Glad he insulted me into racing the bikes!
Is the popping just the wind? I bought a used grom and it starts popping at 55mph. Didn’t do it at first. I think it’s the valves but I’ve never done valve adjustment so I’m hesitant to try. And I can’t find anyone to do it for me. Also can’t find anyone to weld an o2 bung for my wideband I bought.
Yes, the popping is just the wind, and my microphone malfunctioning. My grom does not pop at all, even on deceleration. It sounds to me like you have a lean condition- get the o2 bung hooked up ASAP, and adjust those valves! It's not hard - I cover it in my latest video actually: ruclips.net/video/zbNngFAu3J8/видео.html
Skip to 8:25 for valves. Good luck!
CT Gromer thanks man. I appreciate the advice and link. The bike was dyno tuned with the power commander V. So I think it’s just the valves. But I am excited to see what the wideband does. It auto tunes to specified AFR at all throttle position as opposed to the Power commander that is only at 80% and up. Should be a good upgrade with all the others already done
@@timothyvalle2614 Oh yeah, that Autotune is no joke. You'll get it all worked out bud, thanks for commenting!
how are you gonna not tuck in the stock one then tuck in the modded one and say it's way better?
I tucked in both speed runs, just had to tuck differently because the bars are different on both bikes. The modded bike has a cross-member that I had to tuck behind, whereas the stock grom I can tuck my head between the bars which are open with no cross-member. Can definitely see how this would cause confusion though.
Big bore kit next
Maybe in the future, I am about to install a high compression stock bore piston though!
What cam would you recommend me to add to 2020 Honda Grom 125?
The first run on the modded hit 71 for about 10 milliseconds
I'm 6'2" about 235 and I got 62 out of my grom on flat. Only thing that's different is the previous guy put some cheap chinese pipe that I have no idea what it is
that's really fast for just an aftermarket exhaust, especially for your size! Thanks for commenting!
@@CTGromer I just tuck down as far as I can haha. I wanna do some power mods though, just so I can hang a little easier with a couple dudes I ride with
Sean G. They really help. I’d recommend re-flashing the ECU and an intake. Best bang for your buck!
@@CTGromer first thing I'm gonna throw on is that intake. It really seemed to make a big difference for you. I know it gets good miles per gallon regardless, but do you notice a considerable difference with a cam and a tuner in terms of fuel usage?
@@seang.4533 Yes, you'll really notice the intake, and it'll will run safer when you re-flash ECu to richen the air/fuel mixture. Honestly, I didn't notice a significant drop in fuel economy.
What mods made the bike faster?
Hey! all the mods I mentioned in the video at 1:25 in. Chimera air intake, Yoshi exhaust, Kitaco clutch cover (minor) DHM Re-flashed ECU + TB CAM.
What helmet do you wear?
New groms now have another gear
Who's is Tinkerbell At 7:20?
Hahahaha! My good buddy Nathen! He's in a lot of my videos, thanks for commenting!
@@CTGromer , Subscribed. You handled that a lot more politely than I could have. You didn't even use the word anachronism.
@@BrendaEM haha, I appreciate it, he's just being funny, it's the internet. How about the word, "Paramecium?"
What kind of helmet are you wearing?
What's up Chris? I'm running an Icon Variant. Love it.
My man's 5.11 am I right boys
LMAO!!!! I like that. I'll take it bud, thanks for commenting!
Upvote for 7:33 (Bonus Footage)
Glad you enjoyed it! Thanks for watching! God thing Nathen convinced me!
What helmet is that?
Modded grom needs gears -1 on front and +3 to 5 on rear
Once upgraded is it highway legal in California?
Technically not, because it has to be at least 150cc from the factory to be highway legal in California. Its never stopped me though :)
@@CTGromer awesome man do cops ever mess with you because of that?
@@salvadorruiz5791 Never been pulled over on the freeway, no.
Were the tire pressures the same?
Yes they were, that would have some affect for sure.
I need those mods lol
You definitely need those mods. Life changing for your grom!
my stock grom dose 75mph 120 kmph i am canadian a
jeff gallant that’s crazy fast. Do you think it’s because your Canadian?!
🤣 all kidding aside how much do you weigh?
181 BBK vs Stock ... ? 🤔
I'll have to do one like that soon! Not a bad idea :) Thanks for commenting!
Wtf?! My bike was 125 before I started modding (cg titan 125 from 99's Brazilian market). I spend less than 1100 dollars on it between the purchase and the mods and it goes over 100mph. Where the hell is all that cash going?
Comparing those two engines sounds like we are comparing apples to oranges, I'm not too familiar with the engine you're referring to, but I would challenge its reliability against the tried and true Japanese grom engine in a heartbeat, thanks for commenting!
@@CTGromer the grom never made it to Brazil, the only 125cc's honda released down here were the cg "titan" and the cg "fan". They both are not quite as reliable as a super cub (also never made it to our market) but you can find real cheap parts and mods.
P.S. mine has over 70000km ( about 45000 miles) and the only problems I had with it was clogged carburator and gas filter due to dirty brazilian gas and riding without an air filter.
@@guilhermegoldman Thats a lot of miles! I'm going to have to look this bike up!
@@CTGromer in Brazil alone over 7 milion of those were sold, it's the standart bike for milions of pizza and what-not delivery guys! Btw, you got one subscriber!
What’s your weight
162 lbs for me, Nathen the guy racing against me is 145 lbs.
