Frequently Asked Questions

What does 0.80kg spring rate mean?

Spring rate is the force required to compress the spring one unit of distance. A 0.80kg rate is a medium stiffness suitable for average-weight riders on sportbikes.

Why do sportbikes come under-sprung from the factory?

Factory springs are a compromise for a wide range of rider weights. Lighter or average riders need stiffer springs to maintain proper fork height, compression, and handling balance.

Will these springs sack out over time?

No — Race Tech's shot-peening and heat-treatment process eliminates sacking-out. These springs maintain their rated stiffness throughout their service life.

How do I know if I need a stiffer or softer spring?

If your fork feels wallowy or dives excessively under braking, you need a stiffer rate. If it feels harsh or topping out, try a softer rate. Race Tech can help you select the right rate for your weight and bike.
