Max-Cycle is specifically formulated to exceed the demands of highly stressed 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 oil. Its shear stability and oxidation resistance promote greater performance and protection.
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 motor oils. No flushing is necessary prior to use.
Reduces Wear and Tear
Max-Cycle’s high film strength dramatically reduces wear. Take a look at the pictures of cam chain tensioners at right. Each tensioner came from an American V-Twin engine with 10,000 miles of use. Compare the images below.
The difference in wear is dramatic:
 A cam tensioner from an engine that used the manufacturer’s conventional oil. |
 A cam tensioner from an engine that used the manufacturer’s synthetic oil. |
 A cam tensioner from an engine that used Royal Purple after an initial break-in period of 1,500 miles. |
Reduces Heat
Improved combustion and reduced friction help to prevent overheating and to extend the life of the oil and the engine. In an independent test conducted on an American-made V-Twin motorcycle, engine temperatures were reduced 25˚F to 44˚F just by switching to Royal Purple. See graphics below:
