Give your engine and transmission the superior protection of Royal Purple Max-Cycle 10W-40 Synthetic Motor Oil (P/N: 1315), available in a 1-Quart bottle at Straight Six Imports. Specifically engineered for 4-cycle motorcycle, ATV, and powersports engines, Max-Cycle is designed to exceed the demands of highly stressed, high-performance bikes.

Formulated with select synthetic base oils and Royal Purple's proprietary Synerlec® additive technology, this full-synthetic oil delivers unparalleled film strength—up to 400% stronger than leading competitors. This drastically reduces wear, friction, and operating temperatures, allowing your engine to run cooler and free up measurable horsepower.

Key Performance Advantages:

• JASO MA2 Rated: Guaranteed compatibility with wet-clutch transmissions, providing smooth shifting and preventing clutch slip.

• Extreme Film Strength: Synerlec technology reduces wear in the engine and transmission, extending component life.

• Heat Reduction: Promotes cooler engine operation (tests show reductions of 25°F to 44°F), critical for air-cooled and high-stress liquid-cooled engines.

• 10W-40 Viscosity: Excellent protection across a wide temperature range, suitable for both hot and cold conditions.

• Versatile Use: Recommended for all 4-cycle engines, air-cooled or liquid-cooled.

Choose Royal Purple Max-Cycle for reliable performance, increased power, and ultimate protection for your import motorcycle or powersports equipment.
