Max-Cycle synthetic engine oil is 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.
Royal Purple Reduces Wear and Tear
Max-Cycle’s high film strength dramatically reduces wear for a longer engine life and increased fuel economy. Take a look at the pictures of cam chain tensioners below. Each tensioner came from an American V-Twin engine with 10,000 miles of use. The difference in wear is dramatic.

Max-Cycle Reduces Heat
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. See the thermal imaging graphics below:
