A 350X with 20 inch tires will do about 55 MPH

With 18's it will do about 50MPH

Maybe he doesn't know...that's why he asked :confused: Also,trikerider,you have it backwards.Running 20's will get you a higher top speed than 18's ;)

thank you for your useful reply,,,is 8250 the proper rpm to use, the reason i ask is cause i have used that same calculator on my 400EX after i have checked it with my gps and gotten totally different top speeds,,,i know that the calculator is in the ball park,,,thanks alot

I'm not sure, i could check my shop manual and see what redline is, but i dont know if top speed comes at peak tq or hp, they tend to drop off after the tq peak and feel slower. It's probably close enough for a stock bike.

Elaborate on what u mean. for a gearing calculator? I havent found one for the 200x but i never really looked either. The calculator doesent work off just rpm.

i bought a nos 350x engine and just broke in it did 65 on a bushnell radar gun(same model cops use) with stock rear tires and gearing. with 20's you would be lucky to hit 60 depending on if they were rounded tires or flat

A 350X with 20 inch tires will do about 55 MPH

With 18's it will do about 50MPH

maybe with stock gearing but who keeps the gearing stock after going to 18s?


with 18s and 14/36 gearing my 350rx was clocked at 65mph....and this is my low gearing.

It also depends on if the 350x is a piece or not.....
