4-cycle Motorcycle Engine Oil

With most four-stroke motorcycles, the engine oil performs multiple functions, including lubricating the motor, clutch and gearbox. ’s reformulated 4-Stroke 10W-40 Motorcycle Oil is uniquely designed to excel at all three demanding tasks. Engineered with top-quality additives, it provides wear and friction protection in 4-cycle engines. Whether it’s a sport bike, V-Twin, or touring motorcycle, ’s formula maximizes horsepower and acceleration with each throttle twist. What’s more, it provides 40% better transmission protection typical API SL quality engine oil in FZG scuffing test, and up to 20% better engine cleanliness vs. typical API SL quality engine oil in XR250 engine test. Friction control helps prevent slippage and smooth shifting and optimal power transfer in bikes like Road King, Kawasaki , Shadow Phantom, YZ450F, Ducati Multistrada V4 and more.
