“Double Ester Technology for Motorcycle Engine”. This technology made possible to spur on an optimum output by reducing the friction of the oil film while maintaining stable oil pressure.

On the other hand, the slippage of the clutch system is minimized by the increased friction between the clutch plates, this then enables the power output to be increased at the rear tire. Improved power output and more reliability at the same time.

10W40 is for race engines qualifying engines running at high temperature over a wide rpm range. SuperSport, SuperBike, endurance, MX etc.
