ESTER Core® Technology

MOTUL’s decades of expertise in developing synthetic high-performance ester-based lubricants are embodied in this product. By selecting special esters and combining them with an innovative additive package, MOTUL achieves the ideal balance for maximum engine, transmission, and clutch performance without compromising on wear protection and reliability.

Up to 1.3% increase in horsepower: Tested on a Suzuki GSX-R 1000 RR using the new 300V 4T Road Racing 10W-40 compared to the previous version.

Superior lubricity for optimal engine response and acceleration.

Exceptional gear tooth face scuffing resistance with an FZG failure load stage rating >14, indicating outstanding protection.

High polarity ensures maximum oil film adhesion on metal surfaces.

Rapid oil flow from the start reduces critical cold start wear, ensuring long engine life.

Stable oil pressure under all operating conditions for maximum reliability.

Low oil consumption due to the exclusive formulation of synthetic base oils with low volatility.

Clutch performance according to JASO MA2 standards, ensuring the best wet clutch friction engagement in all riding modes.

FZG Test: This test evaluates the lubrication and wear protection properties at the interface of a loaded gear set. Lubricants are classified based on their Failure Load Stage (FLS) rating, from FLS 1 (very poor) to FLS 14 (outstanding).
