I'm sure this has been mentioned on this forum before , but apparently I'm bad at using the search function.

I want to change my rear gearing, but I'm just looking for something around 43 teeth. Does any body know any other bolt patterns that fit this bike? aka a ninja 250 or a kx250f? Both of which are way easier to find sprockets for haha.

Thanks in advance!!!

 

I often use GnarlyParts for my parts:
Primary Drive Rear Steel Sprocket

I know it's a Canadian site, and you're in the US, but they do ship to the US, and keep in mind that the US $ exchange is something 1.25 CDN $ right now, so you'll save some $ that was as well.

Rear sprocket - $27.95 (CDN$), they offer 47-51 tooth rear, plus fronts as well. These are just standard steel sprockets, but a very good price.

New non-oring chains are about $28 from Gnarly as well (they don't last as long, but I don't want to expose a $150 chain to mud and dirt etc. - I'd rather replace the chain more often and save $ in the end).

 

Same sprocket as virtually all KLX250/300. I got mine off ebay. JT makes them at a fair price. Took me about 10 min. to find and order.

 

I think all of those should fit: 41034-1216 DRUM-ASSY,REAR BRAKE $457.94

 

Kdx, kx125/250/500 as well

 

You might consider a 42 tooth oem sprocket (S models).

BTW, I'm using a 39 tooth SF sprocket on my 2006 351.
