- The lubrication is the semi-wet crankcase type.
- The gearbox is used as an oil tank.
- The pump is driven by the clutch and fitted with two rotors made of sintered material:
- One 13mm thick rotor, for oil suction.
- One 8.5 mm thick rotor, for pumping.
- The maximum pressure is 4.2 bars, and at the top of the engine the pressure is 1 bar.
- The circuit consists of a pre-filter, filter, pressure overload by-pass valve and oil pressure sensor.
- The suction is from:
- The front of the crankcase (crankshaft housing).
- The rear of the crankcase (gearbox).
- Pumping is:
- To the oil filter (classic circuit).
- To the gearbox.
