Springs are the most critical element of suspension performance. Ideally they should be matched to suit the combined weight of both bike and rider. Correct spring rate will ensure that the bike settles to the ideal ride height to determine the final geometry of the motorcycle.(Rider Sag)
Springs are available in different wire gauges and materials. The best springs are simply manufactured from the highest quality chrome silicon wire and receive hardening and prestressing treatments.
Race Tech springs are not only made using the best materials and techniques but they are also 100% tested to ensure accuracy. The industry tolerance for spring manufacturing is plus or minus 5%.
