Bought it to gain more top speed on my minibike. It worked well. Didnt break and the teeth held up. I hit 52 with a front clutch bell straight chain having 10 teeth, so a 1:4 ratio.

Gets the Coleman to 34mph. Little to no torque loss at bottom end surprisingly.

I recently acquired a mini bike with a Predator engine that has a pretty rusty rear sprocket. I saw this on Amazon and thought that it would do the job.This sprocket is for a #35 chain and has 65 teeth. The bore hole is 37 mm and the mounting bolt hole diameter is 50 mm. The six bolt holes will accommodate the included M6 socket head bolts which are 20 mm long. Also included are six M6 serrated flange nuts.This kit also has five master links and an Allen wrench for the bolts. I have not yet installed this sprocket, but it seems to be pretty made and I think it will work for me.

Gearing was a little to high for my motor to get to top rpm.
