Piston:
The material of this piston is choosen for its excellent strength to weight properties. The shape of the top of the piston is our 'Compact Combustion Tecnology' which improves the efficiency of the engine. This piston is also milled from a single block which further increases the strength.

Sleeve:
The sleeve is manufactured with 9 transfer ports and an exhaust with booster ports, designed after fluid-dynamics studies, so we increased the maximum power, and taking care of the fuel consumption.

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. The ball bearing was lowered to 5mm.

Conrod:
The R7 conrod is made from a superlight alluminium which has been checked ultrasonic. The specific form of the R7 creates little turbulence inside the engine while running.
