I hate to sound ignorant, but....

Is the stock drive chain on the 2001 YZ426 a 520 x 114 links? I bought my bike used and can not figure out exactly what the previous owner has put on it. The gearing is 14x49.

Thanks for your help.

the factory specs are 520 x 114 and the gearing is 14 and 49 so u are right on with the info u have

I thought the stock final drive was 14/48. No?

My 2002 426 came with the 14-49, But my 02 250F came with the 14-48.

It is on the 450, the 426 is 14/49.

Depends on the year of the 450....

Stock '01 426 is 14/49. It's 14/48 "For Europe".
