looking to change my rear sprocket on my 01 yz426. it has the stock 49 and i wanted to know how big of a difference a 50 would make. i do mostly trails but also like hitting the hill climbs. i'm not too worried about top speed but would still like to go fast.

What kind of riding do you do? I run 13/50 and mostly ride trails. Gears are a little low for desert blasting, but that keeps me alive :lol:

2% is correct and I've been thinking of doing the same. I figured there was no way you could tell the difference of only 2% but everyone who runs that says it's a huge difference. I'm ordering a 50 real soon as I ride a really tight SX track mostly.
