Conrod: New R4/18 conrod, redesigned and made with a special aluminum alloy that allows it to have a high resistance while maintaining the lightness and performance of the previous R4/17. Crankshaft: The crankshaft is grinded to increase the mixture flow and has a special shape to reduce turbulences inside the crankcase. The balancing is done by three inserts made of tungsten alloy and the inlet has a silicon filling to reduce the weight of the crankshaft to improve acceleration. The durability has been significantly improved with the DLC coating. Rear ball bearing: The rear ball bearing has high quality ceramic balls to minimize wear and inertia to improve acceleration and fuel consumption.
