Late Braking Intake And Exhaust Cam
Aprilia SL750 Shiver And Moto Guzzi Breva 1200 Sport
This CAD image shows how both the intake and exhaust cam of the Aprilia Shiver engine (a Piaggio Group design, not Rotax) are driven by a single gear, itself driven by a chain. This allows the exhaust cam to be located lower, providing extra clearance for the radiator and front wheel.
