Wanting to change the final drive ratio on my boys 110 mini hummer. It has a 14 tooth front and a 37 tooth rear. I want more low end toque and willing to lose some top end obviously. This Gio gets a little hairy at the top end for my 7 year old.

I have seen 13 tooth fronts for the 110 chinese motors, but was thinking more like 12 or 11. What should I be looking at for a rear. And where?

Thanks a lot for the help,

Brad

 

Take measurements of the front sprocket shaft and it's mounting holes in millimeters along with your rear and front sprocket tooth count currently installed. Also measure your chain to figure out if you have a 428 or 420 chain using the link below. Then PM (private message) me and maybe I can help you out................Slydog

Sly, do you work at a sprocket manufacturer or something?

 

No, just an auto mechanic with an electrical engineering degree trying to help if I can.....................Slydog
