Royal Purple 26315 Max-Cycle SAE 10W-40 Full Synthetic Motorcycle Oil 1 Quart

Royal Purple Max-Cycle SAE 10W-40 is a premium full synthetic motorcycle engine oil engineered to exceed the demands of highly stressed 4-cycle motorcycle engines and transmissions. Suitable for both street and performance riding, Max-Cycle delivers superior protection whether your engine runs hot or cold.

Key Features:

• Synerlec® Additive Technology: Royal Purple's proprietary additive system delivers significantly improved film strength compared to leading synthetic and conventional mineral oils
• JASO MA2 Rated: Meets the highest wet clutch compatibility rating under the JASO T903:2011 Clutch Friction Test — will not cause clutch slip
• Exceeds API Requirements: Formulated to meet or exceed current API performance standards for 4-cycle engine oils
• Air-Cooled & Liquid-Cooled Compatible: Recommended for use in both air-cooled and liquid-cooled 4-cycle motorcycle engines
• Wet-Clutch Compatible: Safe for use in engines that share oil with the transmission and wet clutch
• Superior Shear Stability & Oxidation Resistance: Helps engines run cooler and reduces parasitic power loss, freeing up horsepower
• Dramatically Reduces Engine Wear: High film strength protects rings, cylinders, and bearings during operation and at startup
• No Flush Required: Fully compatible with other mineral and synthetic engine oils — no flushing necessary before switching to Max-Cycle

Royal Purple Max-Cycle SAE 10W-40 is sold as a single 1-quart bottle (MPN: 26315) and is an ideal choice for riders whose owner's manual specifies a 10W-40 viscosity in both liquid-cooled sport bikes and standard motorcycles.
