Fits with the original cylinder head. Unauthorized cylinder not respecting the 125cc displacement.
Here the cylinder / piston kit 140cc full of great brand ITALKIT Competition for ROTAX engine 125cc 2 Time 123, Aprilia RS, AF1, EUROPA, Pegaso ... and other models. This kit is more like the original, ITALKIT has fully optimized the cylinder to provide a real power gain compared to the original while maintaining excellent strength and reliability engine, a diameter of 57mm for the piston VERTEX is a displacement increased to 140cc.
The cylinder is an aluminum model with an architecture and well designed channels. With specific admission transfers really well drawn and a large exhaust valve, of oval / extended form.
