Description
These precision machined Yamaha Rhino 660 CVT sheaves provide increased ‘travel’ which allows for taller gearing and higher top end MPH. The great part about this product is that there is no ‘compromise’. It provides more top end MPH without sacrificing low end. It does not raise the overall gearing. Low end gear ratio is not affected at all, it simply allows a taller high gear. It’s one of the few performance mods that do not involve a compromise. Please note: this product does require the use of a performance CDI. Please Note: Roller Weights are not included.
