Yamalube 10W-40 Semi-Synthetic Engine Oil lubricates 4-stroke motorcycle engines using a blend of mineral and synthetic base stocks. Under high operating temperatures, the 10W-40 viscosity maintains oil film thickness to block metal-to-metal contact. With JASO MA2 certification, this 1L fluid prevents clutch slippage in high-torque wet-clutch systems.
Key Features
- JASO MA2 Standard: High friction performance rating for 4-stroke gearboxes. Stops clutch plates from slipping during rapid gear shifts.
- Wet Clutch Optimization: Balanced lubrication for integrated transmission systems. Reduces internal drag while maintaining precise gear engagement.
- 10W-40 Viscosity: Resists thinning in heavy road dust and high-traffic heat. Prevents engine wear during long-duration commutes.
- Anti-Corrosion Additives: Chemical inhibitors block oxidation inside the crankcase. Protects internal engine components from rust during inactive periods.
