Fast shipping. Professional packaging. Yamalube is recommended for the Yamaha 400 Big Bear because it's engineered by Yamaha's engineers to perfectly meet the specific needs of their engines, acting as more than just a lubricant by also serving as a coolant, cleaning agent, rust protector, and more. Using Yamalube ensures the engine receives the intended performance and longevity designed by the manufacturer, optimal lube for shifting the 5-speed constant mesh system, including the reverse gear shift, and cleanliness for all engine components requiring high quality lube.

Fast shipping, oil was sealed vey well and did not leak.

Cant get any better gives the exact amount needed

I had tried a different major oil brand for motorcycles. I had clutch slippage, noisy motor and didn't seem to rev. as freely as before. I switched to Yamalube soon after. I must say the change was immediate, no clutch issues, quieter motor. I have been riding cycles for 30 years and am very impressed with the Yamalube.

El Yamalube 10W-40 es de lo mejor para mantener el motor en perfecto estado. El arranque es más suave, protege muy bien en altas temperaturas y se nota que el motor trabaja con menos ruido. Es totalmente compatible con motos Yamaha y garantiza un rendimiento óptimo. La calidad es excelente y sin duda seguiré comprándolo.
