Very high performance race exhaust with an especially wide power-band suitable for everyday use.

Where a four-stroke motor requires valves, camshaft, exhaust and a turbo, a two-stroke just requires a well designed exhaust. A few pieces of sheet-metal modelled to create a form that harmonises perfectly with the layout and size of the openings in the cylinders bore, known as transfer and exhaust ports. The design of the resonance chamber not only influences the removal of hot exhaust gases, but the pulse effect also affects the flow of fresh fuel mixture into the cylinder. On modern two-strokes this technology is the main reason for its superiority over the four-stroke motor.
