I'm gonna need to replace my sprockets soon and am trying to find the stock sizes without having to take them off and count them...are they 15 (front) and 43 (rear)? Also does anyone have a good recommended brand for a decent price?
You are correct sir. 15/43 is stock for your bike. Each sprocket has the count stamped on it as well so you don't have to count the teeth. eBay has alot of different options as far as sizes/ brands. Pretty much the same price as I've seen everywhere else as well
yep 15f 43r is the stock sprocket size for the 05-06 636's. i would suggest stayin with steel sprockets if you want something thats going to last. also depend on how many mile you have on your chain and wat condition its in i would replace the chain to.
