Max-Cycle^® Motorcycle Engine Oil

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:
