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.
