I purchased this for a Coolster xr 125 cc pit bike. Stock was 14t I went up to 17t. Noticable difference. 1st gear isn't as short and top speed improved 3+mph . I've only ridden for a hour with the new sprocket and chain. I got my chain from dyc or something like that. Would buy for another project. Thanks

Exactly what the title says. I purchased the 420 17t 17mm so I can get more top speed on my 125cc DB-x19 apollo only to find out that when I put my sprocket cover back on the chain started to rub the inside of the sprocket cover when the rear tire turned and it doesn’t help that my chain is a 428 and it’s already tight as it is. If I somehow find a solution to this then I will change my rating but until the it’s a one star for me.

Worked so well I was able to get 52 out of my 110 db14 Tao Tao that had a original top speed of 40 over a fight against a friend how said it was impossible 😁

Worked great. Exactly what I need to fix my four wheeler!

It fits and works very good for a geo 110 cc 4 stroke bike better then factory setup. thanks ghf
