Smoother, More Confident Gear Shifts with JASO MA2 Certification: Engineered for noticeably smoother gear shifts in every 4-stroke motorcycle with a wet clutch, this 15W-50 motorcycle oil delivers the precise friction characteristics certified under JASO MA2 (T903: 2023, No. M033MOT209) to prevent clutch slippage while ensuring responsive, confident power transfer from engine to wheel across the full RPM range in street, touring, and adventure applications

Heavy Duty Engine and Gearbox Protection with Ester Technology: Reinforced with Ester technology typically reserved for premium full-synthetic racing formulas, this Technosynthese semi-synthetic motor oil creates a tenacious protective film that resists shear and thermal breakdown at operating temperatures up to 242 degrees C (468 degrees F flash point) with a viscosity index of 152 that maintains consistent viscosity-grade protection across the full operating temperature range, backed by advanced extreme-pressure additives and FZG Gear Test Pass 14 rating for integrated motorcycle gearbox protection under heavy loads

Specialist Oil for Big-Bore, V-Twin, and Air-Cooled Engines: The 15W-50 viscosity grade delivers robust oil film coverage specifically formulated for the high-temperature demands of large displacement, air-cooled, and V-twin engines where thicker oil film provides the elevated shear resistance required for sustained high-temperature operation and integrated gearbox protection across Triumph, Ducati, BMW, Royal Enfield, and other European and classic motorcycle platforms that benefit from a heavier viscosity grade

Versatile ATV Oil, Dirt Bike Oil, and Powersport Lubricant in One SAE 15W-50 Formula: Trusted as both a dedicated atv oil and a high-performance powersport lubricant, this SAE 15W-50 serves every 4-stroke application where the manufacturer specifies a 15W-50 viscosity grade, covering street motorcycles, off-road dirt bike oil applications, adventure touring, ATVs, UTVs, side-by-sides, scooters, and personal watercraft from Honda, Yamaha, Kawasaki, Suzuki, Polaris, Can-Am, and other major powersport brands, with full miscibility alongside existing synthetic and mineral oils

Extended Drain Interval with API SP Certification for Modern Engines: Certified to the latest API SP standard for modern emission-controlled motorcycle engines, this synthetic motorcycle oil supports a recommended drain interval of up to 16,000 km depending on manufacturer guidelines and riding conditions, with Technosynthese base stocks and an oxidation-resistant additive package that maintain protective properties across extended service intervals while protecting catalytic converters and secondary air injection systems on Euro 5 and EPA-compliant motorcycles
