17mm Sprocket
I noticed most front sprockets I am finding are with a 17mm inner dimension. I have seen 18 and 20 as well. I am about to order new sprockets for my TBR7 D. Are the 17mm sprockets the ones used for the China bikes?

My tbr7 uses a 20mm. I think all the cg motors do.

The original Honda Cub used 17mm so most but not all Chinese horizontal engines use the same. Many horizontal 125cc engines use 20mm as well as most vertical clones.
