Description
BP Visco Bikes 20W-50 is an engine oil from the Visco line for four-stroke motorcycles, whether carburettor-fed or fuel-injected. It is compatible with wet clutches.
It is classified to API SL and JASO MA2, so it suits machines whose maker calls for API SL or a lower category together with JASO MA2. The data sheet lists no official motorcycle manufacturer approvals.
Typical figures from the data sheet: kinematic viscosity 19 mm²/s at 100 °C and 172 mm²/s at 40 °C, viscosity index 122, density 880 kg/m³.
Application
Four-stroke motorcycles with carburettor or fuel-injected engines where API SL or a lower category and JASO MA2 are recommended.
Worth knowing
On codes, the nearest car oil in the catalogue is BP Visco 3000 20W-50: the same SAE grade, the same API SL category and a viscosity at 100 °C of 18.6 mm²/s against 19 mm²/s. BP aims Visco 3000 at petrol engines and it has no JASO class, so the only code that separates the two is the JASO MA2 on Visco Bikes. That class is what shows the oil has been tested on a rig with clutch plates. Another 20W-50 of the Visco line, Visco CNG, is designed for passenger-car engines running on compressed gas and has only API SG and CD, with no JASO class.
Why a car oil without such a test can ruin a motorcycle’s clutch is explained in the article on choosing oil for a motorcycle. Other oils with the same wet-clutch class are collected on the JASO MA2 page.
