I have a1000cc side by side that will do 80mph, still haven't found the need to go 50
Mine tops out at 25mph
I got it up to 28 mph going down a steep hill
That is fast enough for me on dirt
I go 100mph on 2 wheels on the street at times and cruse at 90 most of the time. Hard flat surfaces are a lot different that uneven dirt.
