Yes, Bell Scooter can be safely used with the Yamaha Cygnus Gryphus, as it is designed for scooters equipped with CVT (Continuously Variable Transmission) systems.
It is suitable for both the engine oil and gearbox (final gear) lubrication areas.
■ Recommended Usage and Ratios
・Engine oil: Add 5–10% of the total oil capacity
Example: For 1 L of oil → add about 50–100 ml
・Gearbox oil: Add about 5% of the total oil capacity
Example: For 150 ml of oil → add about 7–8 ml
■ Notes
・The effect becomes noticeable after several tens of kilometers as the additive blends into the lubrication film.
・Keep the total oil volume within the manufacturer’s specified capacity—overfilling can alter viscosity balance and reduce performance.
■ Expected Effects
・Smoother throttle response and lighter engine revving
・Reduced gear noise and friction
・Improved quietness and durability
・Extended component lifespan
