Yamaha® Rhino 660

Yamaha's Rhino 660 offers an abundance of features that has put it at the top of the UTV ranks. The 660cc, liquid-/oil-cooled, four-stroke, five-valve engine responds perfectly to the HMF Dual Performance System. On the dyno, we noticed a 14% increase in horse power across the power curve with an insane amount of torque. This allowed the Yamaha Rhino 660 to travel through terrain it never used to be able to conquer.
