Motul Transoil Expert 10W-40 is a 1‑liter technosynthesis transmission lubricant formulated with ester components for reliable gear protection and smooth shifting in both road and off‑road wet‑clutch applications.

Designed for vehicles that use separate gear lubrication or require a lubricant compatible with wet clutches, Motul Transoil Expert blends synthetic and mineral base stocks with ester additives to improve shear stability and shiftability. This 1‑litre pack is suited to motorcycles, ATVs, utility vehicles and other machines needing a multi‑area transmission oil that performs across varied riding conditions.

How does Motul Transoil Expert 10W-40 improve shifting and gear protection?

The ester-enriched technosynthesis formula enhances the oil's film strength and resistance to shear, helping maintain consistent viscosity under load. That creates smoother gear engagement and long‑term protection for gear teeth and bearings without compromising clutch friction characteristics.

• Technosynthesis base for balanced synthetic/mineral performance
• Ester additives boost film strength and thermal stability
• 10W‑40 viscosity supports cold starts and high temperature operation
• Formulated for wet‑clutch compatibility to avoid slip
