Description
Big twins, cruisers and older air-cooled street bikes often run best on a heavier 15W-50 oil that holds its film under sustained load and higher operating temperatures. LIQUI MOLY Motorbike 4T SAE 15W-50 Street is formulated to protect that kind of engine through stop-and-go city riding as well as long stretches on the highway, and it is sized here as a 20 liter drum for shops and riders who need volume rather than a single bottle.
- SAE 15W-50 viscosity suited to air-cooled and larger displacement street engines
- Formulated for engine cleanliness and reduced wear
- Stable film strength under sustained heat and load
- Supports smooth clutch engagement in shared sump designs
- Consistent lubrication across long service intervals
This viscosity fits cruisers, touring bikes and other street four-strokes where the manufacturer calls for a 15W-50 oil rather than a lighter multigrade. The 20 liter size is intended for dealerships and shops handling multiple oil changes on this class of bike. IPD Racing carries this drum for that kind of steady bulk use.
Shops that service a lot of American V-twins and older air-cooled tourers will get more consistent results standardizing on this 15W-50 rather than substituting a lighter oil out of convenience. Keep the drum in a cool, shaded spot between uses so the additive package stays stable through repeated draws.
