your clutch wont work then the engine idles at 2200

top speed is determined by rim size and max RPM

no because it engauges below idle so you cant start the engine without it engauging top speed with the governor is not going to be to high 30ish without it 50 ish

thats about the highest geat ratio it should pull stock with the governor you will never see 50MPH without it you should be able to do it but the rest of the bike is going to need extensive modification wheels bearings tires forks the stronest frame you can find its not a cheap build alot of the guys have $1500-2000 in there 212cc bikes
