A Core deposit is a form of deposit you pay until returning your old part. If you don't have the core at the time of purchase, you must pay the core charge. That charge is refunded to you when you return the core.
Max-Cycle is specifically formulated to significantly improve motorcycle engine (and transmission) performance. It's recommended for use in both air-cooled and liquid-cooled 4-cycle engines and it's compatible with wet-clutch transmissions.
Formulated with select synthetic base oils and Royal Purple's proprietary Synerlec additive technology, Max-Cycle provides unparalleled film strength that is up to 400 percent stronger than the leading synthetic and mineral oils. Its shear stability and oxidation resistance promote greater performance and protection.
Synerlec greatly reduces engine wear - including ring, cylinder and bearing wear. It continuously adheres to metal surfaces, even after shutdown, to provide instant protection at startup until a full fluid film can be established. Max-Cycle exceeds API / JASO new warranty requirements and is compatible with other mineral and synthetic motor oils. No flushing is necessary prior to use.
