R4000 RS is a semi-synthetic, ester-based, high performance motor oil for 4-stroke motorcycles.

• Engine protection
• Synthetic Plus
• Anti-corrosion and anti-oxidation
• Resistance to wear and tear

R4000 RS is ideally suited for 4-stroke road or dual-sport motorcycles with a wet or dry clutch, that comply with Euro 2, 3, 4 or 5 emission standards and are equipped with exhaust and emission treatment systems.

R4000 RS offers high shear resistance, ensures optimum lubrication and provides optimum protection and longevity of the engine and gearbox.

The oil leaves a film on the upper parts of the engine even on a cold or stopped engine thanks to the magnetic properties of the esters that prevent the oil from draining completely back into the oil pan.

Compliant with the JASO MA2 API SM standards, it offers the highest level of friction to ensure perfect clutch operation during start-up, acceleration and at maximum speed.
