top speed of about 55km/h
It'll hit 100 if you shove it off a cliff. Seriously, your question cannot be answered without a lot more information. Year, make and model to start. Stock or modified? On what terrain? Your question...
I have 2010 366 and it will do about 50mph but I have 27" swamplites on it so im losing top end speed.
I have one that is piped that will do about 105 mph
Approx 60mph to 70mph is the top speed of Arctic Cat 400 ATV.
