BikeMaster 10W-40 Full Synthetic Oil

For bikes that actually get ridden

Real-world notes (what you’ll notice after a change)

• Stays put at operating temp, so shifting and clutch feel don’t change mid-ride.
• Full synthetic base helps cold starts; fewer nasty dry-start grinds on short trips.
• Formulated with clutch compatibility in mind — no slick additives that make wet clutches slip.
• Holds up to shear in shared-sump transmissions; important on bikes that eat oil when pushed.
• Practical packaging: quart for single services and top-offs, gallon if you do multiple bikes or want less wasted trips to the shop.
