I don't have a DR650.
I don't have an off road machine.
I don't even have chain & sprockets... Shaft drive baby!
38 minutes of totally un-necessary information for me, yet I still enjoyed it from start to finish, as I do all your videos.
Good work Mark. Well done. Have a beer.
+Revilo Rider so because you have a shaft drive you miss out on the joy of simply changing final drive ratio. your life is so much poorer for that. :)
no DR650? you poor man. my life has been so much better since I added a DR650 to my stable. only one thing to do...... buy one immediately
Hey Mark, great video! I watched most of your DR650 (Max) vids a year or so before I got mine, and now that I have my bike I'm rewatching most of your vids as I work through my mods. You make fantastic content, and just wanted you to know that your videos are holding up well through the years. Don't ever get rid of Max! Cheers! Brad from New Hampshire USA
Thanks mate!
Your old videos have aged very well, still awesome. Great explanation.
Dude! I have been riding motorcycles for 30 years and I've never understood what the hell "tall" versus "short" gearing meant! Best explanation I've heard (especially since people use these terms and never explain them ... like they're supposed to be obvious!). Thanks!
Great to hear mate and my pleasure! :-)
Ok so there is a thing called 'Google search'.
I typed in 'tall vs short gearing'
this is what I found . . . .
www.badasscars.com/index.cfm/page/ptype=product/product_id=398/category_id=13/mode=prod/prd398.htm
if I can do it in 5 seconds, there is NO reason why you can not do it also.
The internet is a great tool for finding out what terms commonly used actually mean.
Thanks for taking the time to do these vids. I just installed Barkbusters onto my DR today and the next mod is the rear sprocket. Nice to watch someone else do all this stuff first!
No worries mate! :-)
The "rubber seal" on the front sprocket is called an "engine sprocket dampener" in the manual. It may have some utility after all.
Great videos. Many thanks.
good video, I run 44:15 on my DR. Good offroad, without beeing too buzzy (revving) on the highway.
One other thing. I use kero to clean stuff up. Not onlyl does it dissolve grease and dirt etc, but it gives everything a light lube as well. Kero is probably a little cheaper than contact cleaner
Hi Mark.. I bought a brand new Dr 650 Tanami Edititon 2 weeks ago after owning old Bogan killers all my life. Then I broke a couple of ribs at work 3 days after I picked it up. Videos are helping. I can’t wait to “ keep on riding “ cool bananas 👍
Finally someone SHOWED the front sprocket sides and how to place it! Took me a while to figure it out when I did mine. That rear fender cover has been on my list for a while. The top plate for luggage goes well with it. Procycle has a cool sprocket retainer as well. It will do 13-16 tooth, just in case you decide to go mountain goating. Great video brother. I'll be doing my suspension in a couple months especially after seeing the sag difference.
This video is gonna help me re gear my dr650sm with 15/48. Really appreciate the video mate.
One thing to keep an eye on when messing with sprockets is the swing arm rubbing strip, especially if a smaller front is fitted. Some bikes are prone to them wearing out prematurely and the chain may start taking chunks out of the swing arm!
they looked like the easiest front sprocket bolts to remove in the history of front sprockets!! I really wish mine was that easy when I did the change over....... then again I have a V-Strom. Great vid and some really good tips for things that may cause a headache!!
Great visualization of tall and short hearing. Well done!
Another good video Mark. That thing the rear sprocket attaches to is a cush drive (cushioned) . Always check the rubber inserts for wear, doesn't hurt to have a set laying around for the time you pull the rear wheel and see them damaged. I enjoy your videos long or short so change a thing. Thanks for sharing.
Hi Mark - realy liking your down to earth videos- for all the time it takes I always throw a ratchet strap over the bike to the jack when doing wheels after it fell off the jack , what a bastard it was to pick up with no wheels on !
Yeah would be good idea! :-)
great info on the front sprocket and which way it goes around, I couldn't see it in the service manual. if you wanted to do the rear sprocket as per the manual you should Torque them down to the specified tourque and you should do the up progressively in a star or opposite side pattern. none the less it obviously dosent matter because you have ridden it many 1000's KM since. keep On riding mate!
+maXim0200 Thanks mate! :-)
outstanding presentation, thank you for the enlightenment
+George Hart - Thanks mate! :-)
When ever you need the gear ratio it's driven/drive so ur original ratio is 2.733:1
Very well explained ! Now i have the DRZ/SM 400 when i go from the street tires to dirt tires should i just change front sprocket or both ?
A good tip is to keep two chains of different length for swapping back and forth as needed, I like to keep spare chains in old sour cream tubs swimming in chain oil
are you supposed to lengthen your chain if you increase your sprocket by a tooth or 2 in the front?
Gday , the best and most effective explanation about it,thankyou.
I dropped my front down to a 14 t, and was told not to bother putting on any front bracket or bolts to hold the 14 t sprocket in place tight,... the front sprocket may wander alittle on the shaft but wont do damage or come off. 2 yrs later it s still running fine.
you explained that very well. thanks . i know the video is old but still very useful
my xr400 dualsport is currently running 16/40 and the stock is 15/45.... that's way taller than stock yet it still screams at 100. well most ppl online say it's fine but it really seems it's doing 6k rpm. wish it had a 6th gear
+NzJohny :-)
That's a bloody great bloody video keep up the good bloody work absolutely blood good advice bloody marvellous
Mark, Been a follower of the both of you for a long time, still wondering how you are still under 10k subs.. but that is beside the point...
That is one clean front sprocket... seen a number of them full of gunk, after cleaning them people saying it has more power..
As for sprocket sizes, Speed/Rpms have a look at Gearingcommander. after you load up your bikes settings on the top, down at the bottom in 'Relative sprocket & chain wear due to drive train changes' you can see the wear indicator for different combinations.
Having a quick look at it, 13-41 will give you the best wearing combo of the ones you have listed.
Good stuff mark, that dog is always get some air time . The way that front sprocket is held on is so much better then the 1 big nut on most other bikes I've seen. Cheers
+MX Tex 🚲 the dog has to give its woof of approval.
stuff that
hi mark, did your bike turn in quicker with the shorter wheelbase, do you remember?
You WIPED off final ratios I was going yes I can relate to CAR diff ratios!! All good I found it really informative much my helpfull cheers
G'day Mark! Let me please try to explain what the difference between more higher and lower gear ratio. If you got a lower gear ratio than you'll get a lower speed, but more higher torque on the rear wheel. And contrariwise in the opposite case. I hope, I didn't repeat your words from the video (I don't know English pretty good).
For me, the easiest way to understand how putting a bigger/smaller sprocket on the front/back, is to visualise what happens when you change bicycle gears with the derailleur. Many bicycles have three large diameter sprockets on the front, and 7 smaller diameter sprockets on the rear. If you’ve ever ridden such a bicycle then you’ll understand the difference a larger sprocket on the front and a smaller one on the back makes, or a smaller one on the front and a larger one on the back. You feel it in your legs. Same principle, of course, with a motorcycle. How nice would it be to not only have a gear box, but the choice of two sprockets on the front and rear to choose from...somehow I don’t think that would be very safe considering the horsepower!
I bought a used one with a 16 tooth front sprocket?? What does that mean
The gearing is higher. Lower rpms at speed. Mine has a 16 front at it seems pretty tall. As I can hit close to 40mph in 2nd without it screaming. A smaller front would wind out quicker.
Thanks for the videos, you are such a crack up for us "American guys"
he's a silly mug for us Aussie's also :)
Crackin you up?
I'm an Aussie and he's makin me cry. He's a fuckin tool.
How has the 44T sprocket held up? I've read reports of aftermarket front sprockets causing accelerated wear on the countershaft, due to different tolerances and material specifications.
All good! :-)
Thank you Mark I spent two bloody hours trying to get the retainer on the flat side ... and know I know it spins slightly to line up the bolt holes ...lol
The short shuffle was a riot LOL
did you use the stock 110 link chain?
Whats the engine speed rpm at say 100k road speed_ that would give us a benchmark. Us old dirt riders use to carry two front sprockets. One smaller sprocket for low-geared dirt sections, and a larger (taller ) for the highway (transport) sections. Many happy miles on my old 1981 Honda XL500 thumper
LOL as you said no tacho! :-)
Love your work and love your videos. Keep up the good work.
No big deal, but it's always seemed odd to me that the US and Aussie versions of the DR come stock with different size rear sprockets. I also can't find a 44 tooth rear (in steel) for sale here in the US. Believe me I've looked. Anyway, I'm running with a 14/43 setup which works out pretty well for me. Good vid as usual!
Hey Mark , How do you like the luggage plate on the rear rack ? Is it worth the extra dough ? Cheers D.
Cool mark just got the 34 teeth sprocket be interesting to see if i see a difference
Great video
Cheers
Good video Mark, humour and knowledge all in one. Was looking at some stickers for my bike , but see you do not do international shipping dam. Never mind. Ride safe mate.
I'm thinking of coating the counter shaft with anti-seize. Is that a good idea?
Does anyone know what the stock RPM is at 55 MPH (89 km/h) in 5th gear? Currently the bike has 14T, 42T sprockets. I think I need to change to 14T,44T because I have to ride the clutch too much at low speed in the rough. I avoid riding on highways. I live in the US and the stock sprockets are 15T,42T here. Come spring I'll change to 14T,44T or 14T,46T
Hey I like your sort of technical videos like this , does anything need to be done so you can know your speed or does this not change any of that.
Only other minor thing is this was fairly long , feel free to cut it into 2 parts next time if you feel like it but im not complaining I love content like this.
Why don't you stop it yourself, say at the 20-minute mark, then you can come back to it whenever and start from there. Very easy to do you know. I'm not having a go, by the way, just trying to be helpful.
First of all, thank you! Your video's about the DR650 have not only been very helpful. More even so they have been extremely inspiring. I am planning on doing most of the mods you did....myself :-). Without your explanations and help, this would never have been an option. Second: I would like to Download all your DR650 video's. Would you consider bundling them up, all of them, and making them available for purchasing? iTunes perhaps? Just a thought.
I run 14/41 (520 chain) which is a fair compromise I reckon. 520 chain is easier to buy anywhere, is cheaper, and it supports a wider range of sprockets. You can get an Xring 520 chain, WITH both sprockets, for about $150 AUD on ebay.
I must have the 15/42 (Canada)...I find the final drive is way too tall. hard to get going in first on the street, but then it launches. Think I'm going to go with a 14 at some point...
Cheers for the info, i am doing my gearing and this is a big help. Hey are you from Bendigo.
You don’t use a front sprocket chain Gard ?
Yes I do! 👍
Which way around isthe sproket
Love your vlogs. Is the contact cleaner any different to using something like Brakleen?
Great video mate, you do a excellent job explaining the different ratios. What spring rates did you switch too front and rear? Just noticed you haven't fit a countershaft seal retainer, I have heard the seal can pop out, idk if it's true or not, a friendly fyi. Cheers
See all the info here: www.bikerbits.com.au/adventures/DR650/index.shtml
No have not bothered with the countershaft seal retainer... has not popped off yet :-)
Enjoy your vlogs. thanks
Will be good to add a counter shaft retainer under the sprocket
Hey can you tell me what rear rack you had on the DR 650?
B&B Offroad
If you use tire cleaner/shine it doesn’t hurt rubber or plastic. It’s a little cheaper than the electrical cleaner.
your short person, tall person presentation made me laugh. You dag, good vid haha
In the United States, tall gears are the same thing as high gears and you don’t use high gears when you’re going slow. like a transmission is high or low. Can you put it in low gear to go slow. that’s why we call it low and slow.
Good stuff mate.
I think you are trying to explain torque at the back wheel. Higher ratio = less torque, lower ratio = more torque. Do you want to be fast (Higher top end) or quick (shorter 0-60 time).
i can't translate mountain foat. what do you mean with "mountain foat"? thanks bro i from mexico and google translate don't work with this word.
yeah
Think i would put the o ring i there
Yes but founded out it would not fit Lol
Thank you dude!
Such a shame these bikes are so hard to get in Europe (carbs won't pass EU emissions regs).
🤘🏻 🌟 🤘
Its called Final Drive gearing.
you didn't calculate the gear ratio correctly. well you did and then you rubbed it out and used an incorrect method. the one you rubbed out told you how many revolutions the countershaft would do for one full revolution of the back wheel.
Mark do yourself a favour and get a B and B front sprocket cover case saver
😮🤯
You rubbed out the wrong ratios. Its the the small sprocket that drives the larger one.
Its the same as cars diff gearbow etc...
Again arse backwards mate.
13 front 44 rear = 3.38:1 see how that works. 3 turns at the counter shaf to one turn of the rear wheel.
I enjoyed that bloody video...........
just remembered... no tacho on DR650 . hahaha
Great explanation on tall vs short gearing in a way that everyone can understand. We recommend also putting in a counter shaft seal retainer the next time you swap front sprocket. Looks like Vince sells them www.vincestrangmotorcycles.com.au/store/index.php?route=product/product&product_id=134 At any rate, we loved the video as always. And time flies, doesn't it!? Can't wait to hear what you think of the gearing. See you on the next one!
Here is a couple of great websites you might want to check out for lots of great info on the DR.
A great siteto use, to see what different sized sprockets and rear tires do. www.gearingcommander.com/ One thing to kep an eye on is at the bottom of the page where it shows a couple tables for "Relative sprocket & chain wear due to drive train changes."
Another great forum for all things DR is drriders.com/ which has lots of helpful members all over the world. For stuff like this where a lot of DR owners have cut out the front sprocket cover so you can keep an eye on your front sprocket wear without having to remove the cover. Scroll down to Stevo post. drriders.com/topic5224-30.html
That rubber ring behind the front sprocket retainer is a damper ring, which is supposed to help reduse vibration, bit a lot of people toss it.
But there is one item you might want to check out, that being the countershaft seal retainer. A little added insurance for those long rides out into the middle of no where. www.vincestrangmotorcycles.com.au/store/index.php?route=product/product&path=20_63&product_id=134 It became standard equipment on newer DR's from Suzuki, but the older DR's do not have them.
Great videos and keep them coming.
if you want to save weight, shave the beard off and save a gram or two. just kidding.
What are you talking about man?
Lefty Loosey, Righty Tighty.
wow mate lots of info!!! way to much for me!! you aren't a d/h bro!! just get out there aride it bro!! nothing wrong getting the kms up hey!!
