Royal Purple Max-Cycle 20w50 4 Stroke Fully Synthetic Performance Engine Oil is specifically formulated to exceed the demands of highly stressed 4 stroke motorbike engines and transmissions.

Dramatically reduces wear, which in turn provides longer engine life and increased fuel economy. Royal Purple's Max-Cycle shear stability and oxidation resistance keep engines operating at a lower temperature, therefor freeing up horsepower.

Formulated with select synthetic base oils and Royal Purple’s proprietary Synerlec® additive technology, Max-Cycle provides improved film strength when compared to the leading synthetic and mineral oils.

Compatible with other mineral & synthetic engine oils, and no flushing is necessary prior to use.

An independent test conducted on an American-made V-Twin motorbike, showed engine temperatures were reduced by 25°F-44°F just by switching to Royal Purple! The advantages of running Max-Cycle in motorbike engines is clear - an improved combustion and reduced friction help to prevent overheating and extend the life of both the oil and the engine.

Max-Cycle meets or exceeds API requirements and is rated JASO MA2, the highest wet clutch compatibility rating under the JASO T903:2011 Clutch Friction Test.


Synthetic oils enable Royal Purple to make superior lubricants, but it is Royal Purple’s advanced Synerlec additive technology that gives its lubricants their amazing performance advantages. Synerlec additive technology truly is beyond synthetic.

Synerlec additive technology forms a tough, slippery, synthetic film on all metal surfaces. This proprietary film significantly improves lubrication: first, by increasing the oil film’s thickness, and second, by increasing the oil film’s toughness, both of which help to prevent metal-to-metal contact. It displaces moisture from metal surfaces and protects all metals against rust and corrosion. It also fortifies the oil against the detrimental effects of heat, which causes oil to oxidize.

Royal Purple Max-Cycle 4 Stroke use:

  • Recommended for both air-cooled and liquid-cooled 4 stroke engines, & is compatible with wet-clutch transmissions

Royal Purple Max-Cycle 4 Stroke Performance Advantages:

  • Maximizes Horsepower
  • Reduces Operating Temperature
  • Superior Wear Protection
  • Lower Coefficient Of Friction
  • Meets Warranty Requirements
  • Superior Rust/Corrosion Protection
  • Environmentally Responsible
