Royal Purple Max-Cycle Motorcycle Engine Oil Royal Purple Max-Cycle is specifically formulated to significantly improve motorcycle, ATV and snowmobile 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 unparalled film strength that is up to 400 percent stronger than the leading synthetic and mineral oil. 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. It''s available in 10W30, 10W40 and 20W50 viscosities. Royal Purple''s Performance Advantages: * Greater Wear Protection * Greatly Extends Oil Drain Intervals * Increases Horsepower * Increases Torque * Provides Superior Rust / Corrosion Protection * Saves Fuel and Reduces Exhaust Emissions * Keeps Engines Clean * Mates Engine Parts * Will Not Harm Seals Try Royal Purple today and Feel the Differenc

Royal Purple is THE choice for high mile riders!
As a motorcycle technician, I did a massive amount of research before switching to synthetic on my motorcycle. Royal Purple is far and away the best choice, and that is shown to be the case in pretty much every independent test where Royal Purple is included. I use my motorcycle for big mile endurance competitions and it is not unusual for me to run 20,000 miles in a few weeks without changing the oil. There is no other brand of oil I would feel confident in lasting through those type of conditions. Hands down, Royal Purple is worth the expense to protect my hard-working engine.

Surprisingly impressed and blown away
Wow I'm very impressed I use this in my ATV and motorcycle and my dirtbike and I have noticed The motor seems to run quieter smoother and it has seem to have given me about 2 more Horse power and as surprise manly as that sounds I actually dynode my motorcycle before the old change and then 2 days later and there was A difference and it had the same gas in it nothing was done no performance parts just oil so to me that translates to better lubrication of parts to gain hp I know it is expensive but it is totally worth it
