Frequently Asked Questions

What viscosity should I use in my forks?

5W is the standard viscosity for most V-twin forks. Check your owner's manual or fork manual for the correct weight for your specific bike and riding conditions.

Is this compatible with my Harley or Indian fork?

Yes — Maxima Racing Fork Fluid works in all V-twin motorcycles, including Harley-Davidson and Indian Motorcycle fork systems.

How much fluid does one bottle fill?

One 1-liter (34 oz) bottle provides enough to service a complete fork system with room for maintenance top-offs.

Will this reduce fork diving and improve handling?

This fluid minimizes foaming and air entrainment to maintain consistent damping. Proper fork fluid maintenance helps preserve original handling, but setup and preload also play key roles.

Can I mix this with other fork fluids?

No — drain the old fluid completely before refilling with Maxima Racing Fork Fluid to ensure consistent performance and avoid formula incompatibility.
