FEATURES

Sleeve: The sleeve has 9 transfer ports. The special shape and positioning of the ports, improve the internal fluid-dynamics to obtain the maximum possible performance. Lightened CNC machined piston.

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 two inserts made of tungsten alloy and the inlet has a silicon filling to reduce the weight of the crankshaft to improve acceleration.

Gasket: The inner shape of the gasket has a special shape. These gaskets use a special rubber that are more resistant to high temperatures.

Ceramic ball bearing: The rear ball bearing has high quality ceramic balls to minimize wear and inertia to improve acceleration and fuel consumption.
