As an ATV rider you have most certainly seen a shock absorber with two springs and some of you have seen shocks with as many as three or four separate springs mounted.
The simple reason is the never ending desire to find the optimal riding experience and performance of the vehicle. This ongoing quest results in many solutions, one of them is the inflation of springs.
Öhlins Racing has undertaken numerous tests in the past and our recipe for a well functioning shock absorber is two springs that interacts with different spring characteristics.
The main spring has a progressive force curve which means that the spring behaves different depending on the stroke. The force curve has an exponential design with tuneable points where the characteristics of the spring changes, the so called Cross Over Points. The Cross Over Points are a well known factor when you trim your ATV to get maximum stability when making fast turns and rolls. This functionality enables the rider to keep the amount of springs on the shock absorber to just two instead of three or four which considerably eliminates the chances of getting an uncomfortable ride with decreased performance.
A great thing is that you can change the Cross Over Points on the shock absorber thanks to external adjusters without taking off the shock absorber from your ATV.
In fact, the two springs gives us the unique Triple Rate functionality because of the two characteristics in the main spring combined with the secondary spring. This functionality will most certainly give the performance and comfort needed on your ATV.
