Race Tech KTM 990 Super Duke 08

Replacing the front fork springs with the proper rate for your riding style and weight can make a trememdous difference in the performance of your forks. Replacing the springs if they are too firm or soft is one of the best bang for the buck suspension upgrades available.

A High Performance Spring has a high stiffness to mass ratio. In other words, it is light weight for a particular rate. This requires the finest materials.

And, of course, you want the specific rate you're paying for. Most manufacturers hold rates within +/-5%, this means a spring marked 5.0 kg/mm could be a 4.75 or even 5.25. (A spring marked 5.0 could be the same rate as one marked 5.4!) Race Tech Springs have extremely accurate rates.

Chrome silicon, high stiffness to mass ratio, shot peened, heat treated and pre-set (no sacking). These are the finest springs available, period!
