4 STROKE ENGINE OILS
Four-stroke motorcycle engines work harder than four-stroke car engines. So our 4-stroke engine oil is liquid engineered to meet their extreme demands.
Which four-stroke engine oil is best?
If you’re riding a motorcycle with a four-cycle engine, you would be forgiven for thinking it’s similar to the four-cycle engine in a car.
The truth is that motorcycle engines work a lot harder than car engines: revving higher and generating more power per cc than most any car. Staying on top of your oil level and oil changes is incredibly important, and so is choosing a motorcycle oil that meets the original manufacturer’s specification, as well as the demands of the way you ride.
