Shock Springs Shock Springs for KTM

Straight Rate - also known as linear rate or constant rate springs, are where the entire spring is wound at the same pitch, therefore every kg of force has the same effect on the spring throughout its length. For example, if it takes 25kg of force to compress the spring one inch, it will take another 25kg (50kg in total) to compress it the second inch and so on until the end of the travel.

Progressive Rate - are wound progressively from a finer pitch at one end to a coarser pitch at the other, therefore having a rising rate resistance to compression. For example, a 15kg to 25kg progressive spring rate will take 15kg of force to compress the spring one inch, then an additional 17kg of force the next inch and so on until the end of the travel, the last inch takes an additional 25kg to compress it .

Straight rate vs progressive rate? We specialize in off-road suspension (not mx/sx) and prefer the suspension action to be plush to absorb rocks and roots yet firm to resist bottoming. Progressive spring rates allow us the tuning latitude to accomplish this.

These quality springs are manufactured in Holland (WP) and in the USA. Because there are too many variables, spring charts and spring calculators only get you in the ballpark. If you need help with spring rates, please email your information (weight with and without gear, bike year and model, type of terrain, skill level, and what springs you are using now) to slaverace@msn.com. Please be short and concise with your request. Long emails with many questions will NOT be answered.
