The patented CRF technology was created by inventor Fabrice Ramella and is in constant evolution thanks to Adrien Bertin.
The main difference with standard engines resides in the crankshaft design: 1. Turbo-Effect thanks to the angled crankshaft port. 2. Reduced back plate mixture bouncing. Fresh fuel mixture is distributed around the backplate instead of bouncing against it. 3. Acceleration and throttle response is improved thanks to the slots which recover stagnating fuel mixture.
