10W-40 motorcycle oil for 4-stroke engines with JASO MA2, wet clutch compatibility, and stable performance year-round.
10W-40 DBV Two-Wheeler Special is a high-performance engine oil for 4-stroke motorcycles with wet clutch systems. It combines a modern 10W-40 viscosity with JASO MA2 requirements, making it ideal for motorcycles where clutch behavior, shear stability, and engine/gear protection must be handled by a single oil.
In motorcycles, the interaction between engine, gearbox, and clutch is far more sensitive than in passenger cars. That’s why a standard passenger car 10W-40 is not a proper alternative here. This oil is specifically designed for motorcycle technology with shared lubrication systems.
For daily riders, touring, and more demanding sporty use, this is a well-balanced solution aligned with modern MA2 requirements.
Suitable for 4-stroke motorcycles with wet clutches where API SN/SM/SL/SJ/SH/SG and JASO MA2 or a comparable 10W-40 motorcycle specification is required.
Why is JASO MA2 important for motorcycles?
Because the specification ensures proper friction characteristics for wet clutch systems.
Can I use a passenger car 10W-40 instead?
It is not recommended for motorcycles with a shared oil system for engine, gearbox, and clutch.
Is this oil suitable for sporty riding?
Yes, shear stability and a stable lubricating film are key advantages for that purpose.
