For over 2 years and 9,000 miles I've been running a 13/48 with a PBI aluminum rear sprocket combo without issue. I also do not adjust my chain at the recommended Yamaha tension. Closer to 1" of slack instead of 1/2".
Very correct same performance because same gear ratio. Checking it very simple, 13:43 or 13 divided by 43 = 0.30 and 14:47 or 14 divided by 47 = 0.297 round of to 0.30 , so they have the same turns or gear ratio of 0.30. By checking like this you don't have to guess anymore in the pairing of your front and rear sprocket.
Just bought a new-to-me 2014 with 423 kms on the girl. So basically has brand new chain and sprockets... and i'm about to order a new chain and sprockets - 14-49. haha. Definitely worth it in the long run. Thanks for the tips!
what year wr's had that swingarm problem? My 2017 has a bottom swingarm chain slide and it covers all of it from what I can tell, or am i missing it? thanks.
That's really a matter of personal preference. If you have the stock gearing, I would recommend a rear sprocket that's closer to a 50 tooth. It'll be a pretty big jump but you'll definitely notice more bottom end. Keep in mind when changing gearing more than 2 teeth you will have to get a different length chain. I would also search some forums to see what other people are running and liking.
The nice thing about 14/49 is that you can drop to 13/49 if you are riding some tight technical single track. 13/47 or 14/49 seems to be about the tallest gearing that still allows for easy 2nd gear wheelies. 14/47 will loft, but requires a lot of body English, or some cheater clutch input, not nearly as fun.
What size chain would you recommend for a 14/47 or a 14/49 ? Any recommendations on manufacturers & model numbers? Also, once you have geared up, is there any way to recalibrate the speedo for the Wr250r so that it reads more accurately?
With a 14/47 gearing set up you would want to go up 4 links on the stock chain size = *112 Links* If you have questions about gearing, feel free to check out our Gearing Guide Video: th-cam.com/video/mp3GXfiGGj0/w-d-xo.html . Honestly, the Primary Drive Gold or non gold x-ring 520 Chain is awesome for the price. Renthal and DID are also great manufactures.

We mention using both the 47 and 49 tooth rear sprocket in this video. It will depend on what/where you're riding and your riding style. Both do the job and get the chain away from the swingarm.
@@rmatvmc yeah sorry just got it. a case saver will not fit with a 14 front so i will be running 13 stock one and a 45 or 46 rear to have the same ratio as 14/49. would that also disable the swing arm dangers or getting eaten by the chain ?
hey those were some great tips my buddy changed his sprockets and the whole bike performs so much better I'm about to change my sprockets ,,chain and new dunlop 606's on my WR250r ride safe my motorcycle brothers,,liked ( thumbs up )
me and my buddy have wr250r's and that never happened with the stock gearing in fact everyone i know on a wr250r never had that problem it only happens if u put a 12 tooth on the front
Sounds like ok of a deal, but what is all wrong with it? Will it need a new head, cylinder, new uni-cam, valves, piston or crankshaft? What're all the replacement parts needed is what i would find out. If all that is required is a new piston kit/top end then yes. Good deal if you're planning on rebuilding it yourself.
2024 is the year still a great video

Could you do a video for the rear shock, or do you have suggestions or mods that you have done to eliminate the springy nature? Thanks
Very helpful video. Thank you for sharing. I just subscribed.

yamaha wr 250 how much equipment can it carry in weight for travel to work good?
What combination of sprockets would be recommended to get the most torque at the very low end on the WR250R ? Not concerned about top end at all.
That's really a matter of personal preference. If you have the stock gearing, I would recommend a rear sprocket that's closer to a 50 tooth. It'll be a pretty big jump but you'll definitely notice more bottom end. Keep in mind when changing gearing more than 2 teeth you will have to get a different length chain.

What chain do use for 14/47?
I can do second gear, Wheelies beautifully with stock, 13/43. what do you think about 13/49?
I rode the stock set up yesterday on a technical track and abused my clutch, I was gonna do the 53 tooth. I need advice.
Did you have a problem with the sprocket hitting the cover (
If I put a 52 on the rear, do you still think there is a need for the 14 on the front in the conditions you demonstrate in this video?
Just bought my WRR, has 14/48 gearing. Think I'll leave it right where it is.
Do you recommend a steering stabilizer to help with off-road riding?
Tires or sprockes change - install Speedohealer V4 for speedo and odo correction.
Nice, I was just wondering how to correct that.
I have been looking for the answer to this gearing/swingarm question on the wr250r for a long time! Thank You! Thank You!
*bhmavrik* Glad you finally found the answer! Thanks for watching our video.

I was just watching the guy in the background sitting on the rock
Do you have a link for the front and rear sprockets that you put on the bike I would like to do the same thing. Thank you in advance
Of course!

Rear sprocket: www.rockymountainatvmc.com/parts/primary-drive-rear-steel-sprocket-p?c=173&v=12826
went 14/42 .thing does 164km/h .very high 6th gear will sit on 110km in 5th.also did tires
Yeah but acceleration would be terrible.
For 14 19 setup, can you tell me the exact chain length I need on your website. I am making me a shopping cart
When you enter in your bike on our home page it will tell you at the top what your chain length is. For a 2015 WR250R the chain is a 520x108.
in your other video with your bearded buddy he said you guys are running a 14 front and 49 back. what is it ?

Yes, even with just the 14 tooth front sprocket you shouldn't run into any problems.
Very useful tip, thanks for sharing!
SIR IF IM USING A 14 FRONT 47 REAR HOW MANY LINKS DO I NEED ON MY CHAIN.
112

Rocky Mountain ATV MC is a 2005 crf250 worth $500. The engine has to be all put together and the guy has every part to do it

Rocky Mountain ATV MC the crank split and I don't know what it needs but he has everything to fix it
And yes we are planning to fix it ourselves. But I'm only 12 so I'll help and I might get it for Christmas
