i have a 2008 chinese roketa 250 and a honda 200s.the 200s will outrun my 250 by a long shot can anyone tell me why tis is.my first probable thought was to check the sprocket size on each axle, the 250 has about a two inch in diameter smaller sprocket but more teeth on it. is this my problem or what.

 

My wifes 250 arctic cat is actually a Kymco-250. chinese.. runs good, lots of up-grades to do later but fast enough for now. I will look for a Honda 200/250 and see if he wants to race. see how bad the Kymco A/C gets beat. This is the utility one..
