I read that a lot of people are using 13 tooth sprockets on their KLX250's
I just put on Dunlop D606 tires and they're a lot taller than the stock tires so I want to change to a 13 tooth front sprocket.
When I check suppliers no one lists a 13 tooth for the 2006/07 KLX250S.
In fact most don't even list the bike.
I thought that the sprocket would be the same as the KLX300 but the OEM part numbers are different.

Where do you purchase a 13 tooth sprocket for a 2007 KLX250S?

JT sprockets. Afam Sprockets. Sunstar Sprockets. Also any sprocket cross referenced for the Honda XR650L. Hope this helps.

haha I just bought one lol

 

Just curious, why use a smaller front instead of a larger rear?? Going to a smaller front causes premature wearing on the chain. From my expeirience going down 1 in the front is like adding 3 on the back.

 

Cost. Front is way cheaper than rear

 

yeah the price differance is drastic,, and well installation is easier also,, i plan on getting a larger one for the rear eventually

 

I need to have a higher gear ratio because I replaced the stock tires with Dunlop D606's and they are larger in diameter.

I agree that it's better to put a larger rear sprocket on but I only have 1370 miles on the bike and increasing the size of the rear sprocket would mean I'd also need a new chain.
So I'll run a 13 tooth front until I need a new chain then I'll go back to the 14 tooth front and larger rear.
