Hi Derek, great video and explanation! I was always wondering about the functionality of it in a kart. Interesting that it is the opposite to a normal car. There you soften the front to gain more front grip. Keep it up:)
yeah DJ the karts are unique. not having coil spring suspension, you have to control the spring rate of your frame loosening and tightening the bars. do you have a Tony Kart too? or something else? the fundamentals are essentially the same for all modern karts
@@PowerRepublic You are right. Karts are very special! I had an old CRG from 08 with an Iame Leopard the last years. I wanted to try something with a more modern geometry. There was no money to buy completly new. I found a good deal on a used Sodi RS3 from the German nationals 2019 and decided on a new X30 engine:)
the sodi karts are a solid performer. Good work, a used kart with a brand new engine is probably the best combo for cost saving, As it is the engine that gives you the most heart ache and most people can't fix them themselves.
Do you have a video in toe? I wonder if you could do a special miniseries dedicated to just caster, camber, and toe and really dive into them. And perhaps oversteer and understeer. Because those are some of the biggest topics for beginners
Thanks Dez for this video. Learned a bit more today, Knowledge is speed and speed is what we want. I would like to see a video of the row width at the front. What effect does making kart narrower or wider?
I use aluminium bar with lots of holes as a front bar. It's installed to the frame with shrinkable rubber tubing. The idea is avoid my 401R to lose it shape from left side. It tends to rise because so many tracks have long stressing corners to the right.
Thanks for the video, Power Republic! Why do you put in the stiffest bar when the track is sticky, but also when the track is wet and grip is very low?
Hello Sajan, great question and thanks for tuning in. My guess is to cure understeer. At our local track when it is hot and sticky the karts seem to understeer. so we add the front bar as the meeting goes on and the tyres start to degrade. also too, when it is wet, the chassis I don't want to flex in the front, so I add the front torsion bar to stop that so we get some good mechanical jack as we go though the corners. hope that helps, try it out at your local track and let me know how it goes for you?
Great video, but I'm wondering where the flat bar fits in the range of stiffness compared to the round bars when it's fitted in either the flat or vertical positions?
For racecars putting a softer setting on the front anti roll bar increases grip on the front axle. As I understood it that isn't really the case for a kart. It seems to be more tricky?
A kart uses the caster and a wide scrub radius to drop the inside front tire when turning, which lifts the inside rear, allowing the kart to turn. Karts don't have differentials so they need to lift the inside rear or they will not turn.
I have a old CRG I got it second hand with a KT100j I pulled that off and got a PRD fireball 125 TAG on it now it doesn't have a torsion bar or the part of the chassis it is fitted to is running a torsion bar only on tory karts or do you use them on most karts? Im only new to go karts and still building and setting mine up its a bits'a im not going to race as I don't have the money but just go and do laps during the week because I like going fast. and thank you for your videos that are very informative I have learnt heaps.
Thanks for this video, just learned a lot.I'm a begginner in karting, but experience in race car. What about rear torsion bar? I do have a used tony kart chassis, with the front torsion bar. I see the clamp for the rear one, but no bar. In the video, you're only talking about front, is the rear bar can help rigidity as well? Same as sway bar in a car will help pivoting in corner / correcting over/under steer?
i bought my intrepid kart used and it had a teflon bar there. the steering axle is touching the teflon bar(the screws of the axle in the bottom). how can i fix this?
We are the local Tony Kart dealer. And we love the history of the company, arguably the best in the business. stoked to be an outlet for them. Haase karts (and most kart brands for that matter) are all fine and almost the same as a tony kart so the videos should be a good reference to get you started
Hi mate, Im having a bit of a hard time finding a base setup sheet for my Kosmic, would you happen to have one, or suggest a reasonable baseline/starting point setup? Im also here in SEQ and its a 2016 Mercury to be more specific

Hello, I write you from Croatia (Europe) My son have 13 years and he is in Rotax Junior . In Europe min weigh in this class is 140 kg and we are without any additional weight 10 kg over. It is not problem with fatness, hi is just big. We are driving with 401 s a and I have no ideas what to do to reduce the weight. Thank you. Alen Mahnich. Ps your videos are phenomenal 👍 Sorry I don’t now where can I write you a question so i wrote here.
Hey Alen, thanks for the positive vibes. Great question. You could remove - seat stay and front bar - third bearing and cassette - Datalogger - use a tillett t11 VG seat - make customs alloy crash protection - use a lightweight battery But really at 10kg’s over , he’s just grown early and needs to get into senior Category soon with extra weight allowing. Cause you can only really get about 5kg’s off with everything on that list.
Do you know of any seats for a big guy? He's about 300 pounds I want my buddy to ride this beast one good time. Maybe something 20inches wide? Have looked everywhere about to make my own. If you don't have any idea thanks for your time
I had no idea the standard ones are adjustable like that. Id bet most people buy the round ones not realising the standard can be rotated to make it stiffer. The fact its so easy to adjust makes that seem like the better option, so why do people swap if they know??
my guess is that some one won a race with it once, so we all bought the gold one too and then that is why it always wins now. but for the finer tuning of the kart the different bars will flex differently, similar to the different axle grades. 'tune - ability' is key to success with the devil in the details
also the flat bar doesn’t have the same range as the round bars. so the flat bar in the stiffest position is still not as stiff as the gray or gold bars. changing the position of the flat bar is not a substitute for the round bars.
Very good Video! I have been searching for an good explanation about front torsen bars. This helpt a lot thank you.
thanks legend, when do you use yours? I mostly use them to control understeer

Hey Cal, we sure do have video's on castor and camber on our sniper videos, have you check them out ?
can you make a vid were you are racing. like a day at the tracke vid. i think it cut be awsome love your vids bro
Thanks for the idea! anything in particular ya wanna see? or just a race day summary?
Just a race day plz😁
Torsion bars? What the heck!! Great vid Dezzy
hahahah thanks Nick
Thanks Dez for this video.
Learned a bit more today, Knowledge is speed and speed is what we want.
I would like to see a video of the row width at the front.
What effect does making kart narrower or wider?
Hey Jordy, thanks for that mate, great idea. Ill let the media development crew know and we can schedule that in
I use aluminium bar with lots of holes as a front bar. It's installed to the frame with shrinkable rubber tubing. The idea is avoid my 401R to lose it shape from left side. It tends to rise because so many tracks have long stressing corners to the right.
Hey Jusa, did you make the alloy front bar your self?
@@PowerRepublic Yes, I did it from 3mm thick tube. It seems to work, frame is ok after firts season. There's less gap than original to frame.
the gap on the ends?
@@PowerRepublic yes, exactly
awesome, thanks for the feedback
Thanks!
No problem!
Great vid. Is there any way to preload the bar ? (for tracks with turns in only one direction)
not sure, maybe you could design a boss with a jacking screw in it for a unique design

which is the stiffest the cylinder shaped bar or the other standard bar?
gold round bar
Does a otk torsion bar also fit on an other brand like crg?
Depends on the kart. Some yes some no
Hey one more questions about. What is stiffer for the chassis, the flat bar in flat position or the round chrome bar? THX
Very similar but the round bars should be the stiffest setting
You should put a superkart nose cone on your DD2 :)
Hell yeah, whatta ya reckon the top speed would be??
At least 200 km
Is the round gold bar stiffer than the standard bar that comes from otk?
great question, I have never bend test them both to tell, but the internet would suggest the Gold bar is the stiffest
@@PowerRepublic oh ok thanks 👌🏽
Great video, but I'm wondering where the flat bar fits in the range of stiffness compared to the round bars when it's fitted in either the flat or vertical positions?
round gold is stiffest. then silver then chrome. then vert flat bar, then flat bar horizontal .

more art than science with karts. sensitive little suckers

love this! what will be your recommendation if its a tight and technical track? using OTK FA kart.
Tight and twisty I use no bar. And a narrower front set up.
I wonder if these would work on a Freeline chassis. 🤔
Yeah its the same principles, and most of the modern frames all have the same tube layout. Do you have a Birel or Ricciardo?

Hey Jon, thanks heaps for tuning in and sharing the videos
Love your videos
Quick question am about to buy a new steering wheel what's the difference between 320mm and 345mm apart from size lol.
Hey Boss, thanks heaps for the positive vibes. the latest ones are the High grip type, and that's what I would get IMO

hey, welcome to the club. karting is mad fun and glad you are liking the channel. no one really uses them anymore so OTK have deleted them for now
What brand are your T handle Allen wrenches and where can I get them?
Hey Randy, we sell them here at Power Republic, they are Italsport. where are you located?
@@PowerRepublic Im in Il USA
i bought my intrepid kart used and it had a teflon bar there. the steering axle is touching the teflon bar(the screws of the axle in the bottom). how can i fix this?
Hey Panos, could you run the bolts up side down so the nut is on the top and the counter sunk head and washer is underneath ?
@@PowerRepublic i will try do to that. but is it easy to turn around the uniball? i never tried to to that and i dont know how it is done
maybe send us a photo so I can see the problem and then give you a solution to fix it
@@PowerRepublic ok but where should i send the picture? On instagram?
IG DM is probs best
Why do you only make videos on tony karts? What's your opinion on Haase karts?

neutral front (castor arrow's forwards top and bottom) with 1mm Pos toe

But really at 10kg’s over , he’s just grown early and needs to get into senior Category soon with extra weight allowing. Cause you can only really get about 5kg’s off with everything on that list.
Ps you can use 3L fuel tank too instead of factory 8L tank
What about the rear ? when is that used
almost never. haven't used one in ages, but it would stiffen the rear of the kart
@@PowerRepublic cheers mate. I'm 14 stone so my chassis is gonna flex 🙈🙈
@@robinafandale yeah boi, test it out if your kart flexes too much
@@robinafandale dude I'm 95kg I wonder if I need a rear torsion bar?

Should be able to buy a XXXl or 38cm seat. Check Comet Kart Sales in USA

Yeah sometimes you need that little bit extra, guess that's why the gold bar is so popular
My kart has only a provision for a rear bar! So what then?
no one really uses them, except maybe a really really heavy driver
I'm 212 lbs So 🤣
Don’t Forget to remind your viewers the bars are required on OTK chassis and cannot work without ;)
great tip, will do
A designer opened a closet. Looked at a coat rack. And invented the torsion bar.
yeah that's is as simple as they are really
