The GP Racing Spec oil is a competition blend and as such offers high thermal resistance, optimization of engine power and enhanced clutch and shifting performance, while the Hi-Performance oil provides durability, thermal stability and increased fuel efficiency, the company claims. Both oils are available in SAE 10W-40 viscosity grade and meet industry standards, including JASO MA for four-stroke engines. Web: Yamaha-motor.com
