Developed for both racing and spirited street riding, this oil provides an ultra-stable lubricating film that withstands extreme thermal stress and high RPMs.

Key Features
-
100% Fully Synthetic Technology: Formulated with premium synthetic base oils that offer unmatched shear stability. This prevents the oil from breaking down even during track days or long-distance high-speed touring.
-
Optimum Wear Protection: Creates a high-strength protective layer on all moving parts, significantly reducing internal friction and extending the life of the engine and transmission.
-
Race-Proven Clutch Performance: Fully compliant with the JASO MA2 standard. It ensures perfect wet-clutch engagement, preventing slippage under high-torque loads and providing a “click-into-place” gear shifting experience.
-
Extreme Temperature Management: Designed to maintain its viscosity and lubricating properties in both air-cooled and water-cooled engines, even when pushed to the redline in hot climates.
-
Engine Cleanliness: Advanced detergent additives keep the engine’s internals free from deposits, varnish, and carbon buildup, ensuring the engine performs at its factory potential for longer.
-
Low Evaporation: The high-quality synthetic molecules result in extremely low oil consumption, meaning fewer top-ups between service intervals.

Maintenance Tip
To experience the full benefits of this fully synthetic oil, ensure the engine is completely drained of old oil before refilling. For performance motorcycles, a drain interval of 6,000 to 10,000 km is typical for this grade, but always check your oil level via the sight glass every 1,000 km. Always pair this oil with a premium high-flow oil filter.
