I get a whopping 58 mph. top speed ! but I have a little engine work with a better ignition box & grizzly sheave. Still need to upgrade my carburetor & exhaust then it should break 60 I think.
It's not really about the top speed though, increasing the Rhino's hp output that is. It's fast enough stock to get you where you want quick enough & has plenty of power to climb hills like I prefer so all improvments are the product of OCD.
These things are a blast stock.
