PostSubject: rear sprocket size   Mon Apr 11, 2016 3:35 pm

I just took ownership of a 2103 WR250R that has had the rear sprocket changed out.  I think the front is a 13 and the rear is a 49.  It seems I am out of first gear BEFORe I hardly get rolling.  

Is this rear too big and what should it be changed to?  

What came stock on the bike?  I understand the OEM one was too tall.  Correct?  I plan on road as well as forest service road riding.
Thanks

43 is stock...48 is very popular. myself i run 46. great on the street and enough punch in the slow trails. i didn't have a problem running stock in the tight stuff either.

I swapped out my 43 for a 48 too. The 43 was fine if you weren't doing a lot of true off road and required down shifting in the hills, 6th gear didn't get a lot of use for me. My son and I both switched out the 43 to 48. It all depends on what type of riding you do.

I have a 43 that I would trade for the 49 if you want.

Try a 14 tooth front sprocket with the 49 tooth rear, this is cheaper, easier than changing the rear and keeps the chain from wearing the slider, its a win, win.

I run 14-50 for mixed riding and little to no highway riding, I tried 13-50 but found first too slow to use much at all and 6th too slow on the road too, 13-48 was alright too and just a little lower geared than 14-50.

Yup the 47 to 49 with a 13 front seems to be the best of on and off road, I would not go to a 12 on the front seems to be too much ware on the swingarm slides.

I have changed from a 12 - 48 to a 12 - 50 for trail riding ( tight, steep and roots ).
Bike is still able to do 60 mph. I also have 13 and 14 for the front if I am riding more road.
The lower gearing was great on the Oregon dune - hill climbs were done in 3rd with 2nd available for the last 1/3 of the hill. With the 12-48, 2nd was used and we were not always successful.
I have over 10000 Kms with a 12 tooth front and have minimal lowere swing arm wear.
Having too tight of chain promotes the wear.

I 2nd BigLake's sage advice.  Try a 14T front with your existing rear for all-around use, and switch back to the 13T for pure off road trips.

The ratio you will get with 14/49 is just a little steeper than stock 13/43 (which most agree is too wimpy anyway).  

I'm guessing you have a 112 chain, and should be able to run both the 13T and 14T fronts with it to affect your gearing.

Now all you need to do is fight the little b__s__d tabs that lock the nut to the output shaft!  wink

I recently changed my WRX with Shinko 244's on the 17" rims from the stock 43 to 48. I almost wish I went with a 47, the 48 seems like I'm revving the piss out of the bike when on the highway ( I need to check my rpms via the C1 mod next time I take it on the road). Though the 48 does do very nicely on the dirt, so I'm going to keep it for now.
