Common questions
What viscosity is this fork fluid?
This is a 15W racing fork fluid, designed for high-performance damping in V-twin fork systems. Always confirm the recommended viscosity for your specific bike and riding style.
How much fork fluid do I need to change both legs?
A 1-liter bottle is typically sufficient for both fork legs on most V-twin motorcycles. However, always consult your service manual for the exact capacity specific to your model.
Can I mix this with other fork fluids?
For best performance and to avoid potential compatibility issues, it is recommended to completely drain your forks and refill with fresh Maxima Racing Fork Fluid 15W rather than mixing brands.
