Rhino top speed.
You would want to go faster if you had a Rhino with mods that improve handling and stability. My Rhino has a 15" wider track width and 4" longer wheelbase than a stock Rhino, and is an entirely diffferent animal when it comes to stability. Sliding it sideways at 50 mph is no problem at all; it is super stable, super predictable, and so smooth riding that it feels more like a mini trophy truck than a Yamaha Rhino. Too bad the Lonestar long travel suspension and Elka shocks cost so much money to be able to get those results. But a modified Rhino like this has such good handling that it could very easily handle triple the horsepower of a stock Rhino. And a few extra mph from and aftermarket sheave are very easily handled. Mine only goes 55 mph, but even that small amount of extra speed makes it much easier to "keep up" with the Razr's with bigger engines when you're racing them in a desert race in the Nevada desert.
So it depends on what mods the Rhino has, and what you are using it for. If you're using it to ride around the farm, or putt along ATV trails, you don't need more speed. If you're racing it, and have the mods to improve handling already done, then you need all the extra speed your wallet can afford. I wish I could afford another 10 mph, but it starts getting real expensive at this point. [img]i/expressions/face-icon-small-wink.gif[/img]
