4-stroke motorcycle engine oils

4-stroke motorcycle engine oils keep your bike’s engine protected, clean and running smoothly in all riding conditions. The right oil reduces friction, helps cooling and prevents premature wear of critical components.

In this category you will find mineral, semi-synthetic and fully synthetic oils for road bikes, enduro, motocross and ATV engines. Choose viscosity grades like 10W-40, 15W-50 or 20W-50 according to your motorcycle manufacturer’s recommendations and typical ambient temperatures.

For motorcycles and ATVs with wet clutches, look for oils that meet JASO MA or MA2 specifications to ensure reliable clutch performance and smooth gear changes. Higher performance engines and sporty riding styles usually benefit from fully synthetic oils with better temperature stability.

Before ordering, always check your owner’s manual for the required SAE viscosity and API/JASO standard. Selecting the correct 4-stroke motorcycle engine oil and changing it at the recommended intervals helps extend engine life and maintain consistent performance on every ride.
