This is not the throttle tube you are looking for...
For those of you looking to upgrade your stock R3 to this throttle tube to increase the mechanical leverage of the throttle, this is NOT the one you want. The cable cam is not elliptical like the stock throttle tube, but it is exactly the same size, which will not make the throw shorter—only linear compared to stock. Get the factory Yamaha OEM R6 throttle tube, as there are too many different variations from Motion Pro to make this a worthwhile purchase.
