Can someone tell me from which bike I can put rear sprocket with more theets(47 or 48) on XTR
Thanks

Hello gtec, sorry can you explain a bit more in details what you intend to do?

Am I right to assume you want to increase your sprocket pitch by a couple of teeth?

Standard pitch for the rear sprocket is 45 teeth and 15 for the front one, you can see the reaction in revs/power when increasing number of teeth using the attached spreadsheet.

If you need details of a good suppliers please check out B & C Express here:

I know that standard is 45,I want to put 47 or 48 because friend told me(he also has XTR) that he tried one with 48 teeth on rear sprocket and he said that bike pulls incredible and bike is just little slower,170-160km/h

If you want better pick up like your mate did its easier and cheaper to go for a 14 tooth front. Very cheap at only �10 or so from BandC express. It does drop the top speed by a few mph but isnt anything massive. It makes the bike pick up alot easier, you can near wheelie in 2nd with out the clutch and easily in 3rd with the clutch, and it also makes the bike feels as if its more free'er revving.

But changing the sprocket sizes means its changes your speedo read out. Not by much, if you get the 14 tooth sprocket at a indicated 70mph your only doing 65mph in real life. You can buy a speed healer if you want but most dont bother

Yes I know if I put rear 47 then when speedo shows 170 it is realy 163km/h,with front 14 it is 159km/h

I ran a 15/47 sprockets on my XTX for a while. I used a Speedo healer to correct the speedo. The bike is great for the hills & around town but reved high on the freeway.
