The Naraku Performances V-belt is reinforced compared to the original, this is done by inserting strong fibers into it. In addition, the surface of the belt has been optimized to achieve the best possible friction between the V-belt and the variator - and thus the best possible power transmission. Note: As there are different V-belt lengths for models with 12" wheels, the dimensions of this V-belt must match your current one: 788x18mm.
