Yamalube 4R 10w 50
Yamalube 4-R is formulated to be the finest
racing oil available for Yamaha high-performance 4-stroke engines,
making it the motor oil of choice for the Yamaha Factory Racing
Team. Yamalube 4-R is blended to handle the high stress found in
competition engines. Its exclusive blend of oils and additives
minimizes frictional losses for higher performance, while providing
critical protection against ring wear and piston scuffing. It also
resists thermal breakdown, a critical consideration in the
extreme-temperature environment of high-output racing engines
