TriboDyn 10W-40 JASO MA2 is a full synthetic motorcycle oil engineered with patented ceramic coating technology — the first oil to receive a United States Functional Patent in over 30 years. Specifically formulated for motorcycles with wet clutches, this oil carries the critical JASO MA2 certification that ensures smooth, slip-free shifting and reliable clutch performance in all riding conditions.
The proprietary ceramic technology actively bonds a protective film to metal surfaces, dramatically reducing friction and wear while preventing destructive dry starts that can damage engine components before oil pressure builds. Meeting or exceeding JASO MA2 and API SN/SM/SL standards, this 10W-40 delivers exceptional clutch feel, precise shifting, lower operating temperatures, increased power and fuel efficiency, plus extended drain intervals.
Perfect for street motorcycles, sportbikes, touring bikes, adventure bikes, ATVs, UTVs, and watercraft with 4-stroke air- or liquid-cooled engines, TriboDyn provides uncompromising quality and lasting protection with every ride.
