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 youre 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 because they
100% test their springs. Chrome silicon, high stiffness to mass ratio,
shot peened, heat treated and pre-set (no sacking). These are the finest
springs available, period!
** Note: Not all spring
rates are available for all models. We will contact you if you select
a spring rate not available for your bike model.
