Simple maths will tell you the gearing you need..
If top speed is 130 with a 42 rear sprocket. A 44 will be as follows.
130 ÷ 42 = about 3.1
So adding 2 teeth (Double the 3.1) means losing 6.2kmph at the same revs
Front sprocket 15 down to 14 works the same way.
130 ÷ 15 = 8.66
So top speed would be dropped by 8.66 (121.3kmph)
The best case for 110kmph would be a bigger rear sprocket. Reducing the front sprocket too much will make it wear out fairly quickly.
A 14 Front (121.3kmph) then a 46 rear (109.78kmph)
Remember this is top speed. If you do a lot of highway with these sprockets you'll kill it !
Hope this is confusing enough to help somebody out. haha
Keep these videos coming man. I just got a 1996 dr650 for $600 bucks im learning a lot about it thanks to videos like these man I appreciate you. I've already seen several videos of yours. And I've learned a lot I hope it helps to have comments like these from your viewers.
Great video. My brother had just said to me the DR had a very fast first gear because I’ve been thinking it might be a good next bike for myself. So now I need to re consider. I’m 75 & don’t do real rough stuff but I love back gravel/ dirt roads or non maintained roads the best. I’ve also been considering the new KLR-S model or even an Versys X300, as I’m only 5’6”
Really loving this content Kyle.
I'm glad man! Some people are busting my chops over the slightly different content lately! lol
Looking good I'm glad your enjoying your new bike. Always nice to know how to work on your own toys.
Sure saves time and money! :-D
Thank you for your time. TN USA
Looks like you've got the result you wanted. Thumbs up!
I did! :-D
I love my DR650... and for that.... Subscribed! 😁👍
Great Video! Taught me a lot!
The main thing is that you have fun on it good luck stay safe
I will certainly try to do so.
48-50 is too large for me, with the amount of time I spend on road. This 44 is perfect for me. Let's me squeeze out highway speeds for periods of time.
As for the chain, this one is great for me now, and didn't break the bank. :-)
Great job....its so fun to tinker around with your own equipment. By the sounds of it she will be breathing a bit easier in the next vid 😀👍
Yessir! :-D Good thing I don't live too close to the neighbors!
Great vid man
Thanks for this video. Something I have been thinking about doing to my 650.
Highly recommended. LOVING IT so far. Much better bike.
Funny, I just received my new chain and sprockets and then I see your video. I'll put them on the KLR tomorrow.
From an old boy: What you found with the DR650 gearing is quite normal for any dual-purpose motorcycle. I suspect they wanted to keep the revs down on road use so the engine would live through the warranty period (if any). Beyond that, it has been normal for me to re-gear such motorcycles for off-road use and then be cautious about too many revs on a hard surface.
Hey Kyle, i realy enjoy your videos and the way you have to explains things, i would like to see how you adjust the valves on the dr, mine needs it, but there is no good videos out there! Your the only one that can teach me that i can thrust!!! Thanks
I agree with you,the gearing is far to high standard,even in first off road.
I'm a new Dr owner,thought I bought a lemon at first,my bike had a sound that could be mistaken for a big end gone bad,but I hear the exact same sound on your bike
So its a case of they all do that!
Waiting on my dominator exhaust and going to do the sprocket change
great vid mate very informative
Great videos Kyle, PE Islander here and fellow DR owner. I did the JT 14T with the same retainer mod. Though I'm thinking I might try 14/46 for the really tight technical single track, could easily throw a 15/16 back on the front for any long Highway run.
Is there room on the rear change guard for a 46 tooth gear?
Yes there is
Excellent post, thank you for sharing.
Great work, thanks for the info.
Very sensible gearing down :-) looking good
Thanks Richard!
Nice one brother, Bike is really coming together.
Getting there!
Anti seize on the axle
Very nice bike, the DR650. They are great off-road, much better than a lot of people think. I ride mine on some pretty tough trails in the mountains of Colorado and it does great. Also very good on the road for getting to the mountains. I've had mine since '05 and have no plans of getting anything else. But I do have a dedicated street bike, too. I use it for the longer road trips.
Hello Kyle, very nice bike, you should still install hand guards, they are worth gold in the field! And a headlight protection would not be bad! Greetings Tom!
Yep! Winter project! :-) thanks for the advise!
Thanks for the video.
Couple questions;
Did the length of the new chain need to be changed?
What about the polyurethane cushions behind the sprocket? How do you know when to replace them? Was the bike doing wheelies on first and second without clutch afterward?
Great video!
What not a o ring chain i put a 14 on the front and found it made a big difference
Thanks for the video
Cheers
I been runnin' a 13 on the ft. and 4t smaller on the r. A my big thumpers The smaller the dia. on the ft. Sproket the less impact pluse you get transfered into your chain. A little smoother due to less chain snatch on the power stroke will actully make the chain en front sproket last longer especially on a bike like an XRL that has no driveline protection AT ALL (cushy hub OR clutch springs) It totally oppsite from a multi cylinder bike I go with the biggest sprocket I can go bigger on the back sproket for better wear bigger sproket up ft. Makes the chain zip noise a little quieter due its bigger dia. less chain flex
Nice job, I'm facing that exact challenge as to how much reduction is enough but not too much?
I realize this an old video but just for clarification, the links on the chain you replaced were stiff because it's an "O" Ring chain, I doubt any of the links were seized, when you switched to the 520 chain I hope the countershaft sprocket you purchased was a 438. the splines on the 438 are 10mm wide verses 7mm for the regular JTF sprocket.
Im actually putting taller sprockets in mine. I don't do any trail riding and just got the bike because it was cheap and simple to work on. Gonna make it a street bike and doing 80mph on the highway with the stock gearing isn't fun. Not to mention i dropped a valve at 2000 miles doing exactly that, so im a bit weary of high revs with this bike now...
The rhubarb was getting close on that first wheelie after the change.....LOL Been there, don't that. Great video.
haha it's pulling real well. After some more riding yesterday, I'm REALLY appreciating the reduction. much better offroad
Kyle Noseworthy yes. Looks like a fun project. I always enjoy some TLC on a used bit of gear. Some spray paint, grease, metal polish goes a long ways and great results. Very rewarding for sure.
Seriously the most helpfull video i found in this kind of info, thanks a lot mate
Great video Kyle & Thank you! BUT..... BUT... I was ALWAYS TAUGHT/ TOLD To never , EVER, NEVER, USE THAT KIND OF MASTER LINK. Now this was in the days before O-Ring chains. IS A CLIP ON MASTERLINK SAFE???????????????
Hey Kyle. I was installing a counter shaft seal retainer on my bike this morning (I have a 2012), and was amazed to find a 14T front sprocket installed. I knew there was a 44T on the rear (when I bought it used) but thought the front was the stock 15T. I like the way the bike rides and now I know why! However... I still have the 525 chain, and the front sprocket is pointy like shark's teeth... that's not good, the bike only has 1800 miles on it. I'd appreciate your thoughts on that. Cheers from New Hampshire! Brad
Sounds like a PBI sprocket that's on my bike. The installer didn't grind down the dust seal so the chain was riding/grinding on it. My sprocket has shark teeth also. I bought a JT Front Sprocket 14 14T Tooth Suzuki DR650S 2015-2022 DR650SE 1996-2014 to replace it. My bike has 5,000 miles on it. I don't think the sprocket is worn out. The new ones look like that. I bought a JT Front Sprocket "14T Tooth Suzuki DR650S 2015-2022 DR650SE 1996-2014" to replace it.
Mu DR650 with 14T, 42T sprockets is difficult to control at low speed because I have to ride the clutch to prevent stalling the engine. I will definitely install 14T 44T sprockets or maybe 14T 46T. @Kyle how are you liking the 14T 44T sprockets?
How is the chain conversion holding up? I just ordered parts to convert my Dr to 520. What puzzles me is how the front sprocket retainer actually does anything.. looks like it can all slide off if the chain isn't attached
Easy and quick to change front sprockets
Looks like you now need to stiffen up the front shocks.They seem bouncy off road and front end dives between shifts on the road. Nice bike
That's a known issue with the DR650 for sure. Perhaps a winter project. People swap out the front fork springs $$$
And add valves
I use a 16/46 for commuting and drop it to a 15 for slower woods gravel stuff
I dropped to a 14 T in the front and have been pretty happy.
Still leaves a bit of highway speed for all day travel
Thats my intent too
I run about 105 km( as per my GPS) with the 14T. I find the mileage suffers above that and it feels ragged out some.
the content is NOT garbage
I'd have taken a link out of the chain, because its going to stretch during the first 700 miles.
Do u have to change the length of the chain for this sprocket setup? Or will stock length work
I have a 1995 dr650, do you have a chain tensioner on yours? I'm curious how to adjust it
I have a 2020 Dr650 and I want to install a 14 tooth sprocket-what would my top end cruising speed be approximatley?
I just bought a 14 front, Do I have to buy a 44 back and 520 chain also to fix this problem?
How'd you decide on the 520 vs 525?
Great explanation, I understood it all. I have a 2020 dr650se which I bought used 2 years ago, had a 1992 model year before, that one I bought it new. Could you tell me why you sold the KLR ? There is a used one for sale now in my hometown but I hear they burn oil, is it true ?
The KLR doesn't burn any oil, more than any other engine. Bad pistons, rings, and cylinders as the engine ages can increase oil consumption, but that's the case with every engine. I sold the KLR because they're really big and heavy, making it not as suitable for my riding. If your dual sport is mainly commuting, somewhat regular highway and / or street use, and your offroading is nice clean truck roads, the KLR is the bike for you. But at like 450lbs, its a beast for single track or more difficult offroading.
Good ride you good take some beans and bacon i am fixin to have some now
Now you're talking! I'll have to arrange that!
Hi. What about rear tire model?
Mine had a higher top speed than stock with a 14 tooth front due to the fact it is an under powered bike and couldn't push through the air .
I hope if they go the kawasaki route and revamp this bike with EFI they also change the gearing to 6 speed with short low gears and long high gears. If they did that I would buy a new one for sure. not sure why 1st gear is so ridiculously long...
Agreed man! Those changes would really help the bike. I'd love to see them invert the front forks as well, along with an upgrade handlebar and dash setup. Those few changes between our two comments would make this a big time winner for me
Did the previous owner already change out the factory sprocket and chain set for what was on the bike?
Nope! This bike is bone stock. 15-42 is the stock setup. I switched out to a 14-44
so maybe my cagiva w16 speed is right it does about 110 kmh and don't want to give it any more its meant to do 150kmh ,its 600cc
You will regret not putting an oring chain as they last way long specially on a high torque bike rk Japanese oring chain are wot use at the moment and have great results
second this!. I recently bought a Dr That someone put non o-ring on. 700kms and it toast... yes I lube it. I use gear oil.
@@bfjoutdoors406 my oring chain lasted 10k kms, only reason it really failed was I failed to lube the master pin(my first bike, i'm an idiot lol). some links were a bit sticky but other than the master link having slop in it it was ok.
you said 15-44 then corrected yourself. got me confused first watch.
someone near me is selling a '14 8000 miles for 4k. should i go for it?
or a 650 adventure/sport. dr650 seems a lotta fun and just really cool.
It totally depends on the type of riding you want to do! That's a pretty decent price though.
I bought a 14 1100 miles....3 years ago...$4800...tricked it out,sold my Harley.....love it...😆
How fast is it at top speed with the gearing DIFFERENCE? Does it wheelie easier with this set up? MPH please?
I thought stock 15/42 was shockingly tall. Even in 1st at a stop light. I run 15/46 and love it. 65mph is smooth, and technical trails are possible.
I had 15 and 43, then went to 44 because everyone said so. Seemed to need gear changes more frequently so went back to the 43. Very happy with that for adventure touring and easy off road.
ok 10:37 no this information is false. do not remover the rubber or swap from 525 to 520 chain and sprockets. if you do the splines on the countershaft will wear prematurely due to the sprocket flogging back and forth on the shaft,
cush drives are necessary on the road, you're 100% right.
44 rear is still to small you will find that you will have to go to a 48 50 at least
How was motor rev on stock everything at 110kms looking at this bike for doing some highway travel this summer coming and at 110 is the motor stressed out much
Completely stock, these bikes are FAST (for a dual sport). 110 kph is easy peasy. Just doddling.

Thank you very much I been eyeing this bike up for a while now and planing a long trip from Alberta to nova Scotia to see family and do some riding and drive back to Alberta if I can with the covid if not plan on going somewhere and exploring some trails too
@@mikeferdinand5226 holy cow that would be a serious ride!!

Yeah it would be but I won't be in no rush just cruise along see some sights along the way explore some trails if I find any along the way lots Back home to explore on and new I don't gotta worry about it 5 year warranty with it brand new I wanna enjoy my summer well try to with all that's going on plan on buying it end of December
@@kyle_noseworthy
Just trying to see if it's worthy enough for a trip like that
I don't know if it's the safety culture embedded in my head but it really bothers me to see a grinder without a guard on it.
I don't like it either!
Get a chain breaker.
Looks like your chain could use a little lube to free up those stiff links.
Yeh?? Was thinking the same thing. Guys gotta lube his chain.
That old chain was super dirty ... needed a good soak and scrub.
the easier they wheelie the better!!
Hay Kyle can you make a knife out of that chain?
Lube the AXLE
Hay Kyle can you forge that chain into a knife?
I'm helping a friend select front and rear sprockets for his dual sport bike. B) is his current ratio. He stalls the engine at low speed and often almost drops the bike. His bike has never been dropped and looks new. Which ratio would be best for this stupid old fool? I think C ) 14/44 would be the best selection but the 44 tooth rear sprocket must be shipped here from Australia and sometimes customs demands an import tax. I assume they are protecting US workers that don't exist (we are ruined. Thank you for your service)
A) 15/42=0.357 geared too high
B) 14/42=0.333 0.357/0.333=1.072
C) 14/44=0.318 0.333/0.318=1.047
D) 14/46=0.304 0.333/0.304=1.095
RPM @ 65 MPH?:
Pro cycle ratios.
E) 14/43=0.325 0.333/0.325= 1.024
F) 15/46=0.326 0.333/0.326= 1.021
Compared to current ratio B's assumed RPM at 65mph, B= 5000 RPM
C X 5000 X 1.047= 5235 RPM (14/44)
D X 5000 X 1.095= 5475 RPM (14/46)
E X 5000 X 1.024= 5120 RPM (14/43)
F X 5000 X 1.021= 5105 RPM (15/46)
5105 RPM (15/46)
5120 RPM (14/43)
5235 RPM (14/44) C )
5475 RPM (14/46)
Not bad math for 5am this morning. I'm still drogy so I'll check the math later today. It's a tradeoff (borrow from Peter to pay Paul) between highway speed RPM and maneuvering on rough terrain at low speeds. D) would be undesirable at highway speeds because the engine would be screaming at 65mph, however I've seen guys stall their engines in the middle of a creek and get very frustrated trying to crank the engine with a wet boot. I had a 4 wheeler with a centrifugal clutch Crossing streams and getting through the rough was a piece of cake. Around 20 years later all the land was closed off so we didn't have anywhere to ride.
I don't know why dirt bikes don't have a clutch like my Cushman scooter, leaver plus centrifugal. It seems the Japanese engineers are a brick shy of a full load. Maybe their managers think they are smarter than the engineers and make a mess of things like they often do everywhere
leaves house, goes 1/2 block, finds nirvanna. wtf. im so jelly.
That was not a speed test... 🤦🏻♂️
A better gear ratio is 16/ 42
Define better?
@@Jason39979 I'm curious as well. Looking to replace my stock chain and sprockets now. Not sure which way to go.
Google sproket ratio Jt and you can down load a chart that will give you the ratio changing sprokets.www.google.com/url?sa=t&source=web&rct=j&url=www.jtsprockets.com/fileadmin/files/jtgearratio.pdf&ved=2ahUKEwjFssOb8L7oAhUUJTQIHar8ClIQFjAKegQIAxAB&usg=AOvVaw3OCifxdE8j2wyG4oeiTwsN
they geared it so high so that a guy would walk in, take it for a test drive out of the showroom and go "Wow this is so fast!" and buy it. That's it. Marketing.
60 mph haha that’s cute try 110 mph on my ktm 525 SX wicked fast bike i’d gap that thing
Sure you're faster. But how much did you both pay for your bikes? And how many miles between maintenance?
Ktm is made for speed and a short lifespan. The dr aint as peppy but does 100 and last ten times as long before rebuild. Both great bikes just what is it you want.
I owned a dr650 for 6 years because I wanted a change,it was the wrong choice I should have bought something else but at the end of the day you get what you pay for don't you,I recently sold it & thank f#*k it's not in my garage anymore,wouldn't recommend the things to anyone & everyone
Why?
