Yamaha WR250R Gearing Tip 

Yeah but acceleration would be terrible.

Nice, I was just wondering how to correct that.

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.

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.

Of course! Front sprocket: www.rockymountainatvmc.com/parts/primary-drive-front-sprocket-p?v=12826 Rear sprocket: www.rockymountainatvmc.com/parts/primary-drive-rear-steel-sprocket-p?c=173&v=12826

Awesome thanks!

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.

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 ?

Yes, even with just the 14 tooth front sprocket you shouldn't run into any problems.

*bhmavrik* Glad you finally found the answer! Thanks for watching our video.

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: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-mp3GXfiGGj0.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.

Second!

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

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.

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
