  • Max-Cycle 20W-50 Synthetic Motorcycle Oil

Max-Cycle 20W-50 specifically formulated to exceed the demands of highly stressed motorcycle engines and transmissions. It is recommended for use in both air-cooled and liquid-cooled 4-cycle engines and is compatible with wet-clutch transmissions. 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. Max-Cycle’s shear stability and oxidation resistance keep engines operating at a lower temperature, freeing up horsepower. 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. Max-Cycle is compatible with other mineral and synthetic engine oils. No flushing is necessary prior to use. Max-Cycle’s high film strength dramatically reduces wear.


Max-Cycle’s high film strength dramatically reduces wear for longer engine life and increased fuel economy. 



Improved combustion and reduced friction help to prevent overheating and to extend the life of the oil and the engine. The advantages of running Max-Cycle in motorcycle engines are clear. In an independent test conducted on an American-made V-Twin motorcycle, engine temperatures were reduced 25˚F – 44˚F just by switching to Royal Purple Max-Cycle 20W-50.

    I've run RP in everything I own from Dirt Track Race Cars to Law Mowers. I absolutely am a true RP user and would recommend this to anyone who has an internal combustion engine.
