The New Generation FM Springs

We've always been a fan of the FM springs, a great balance between comfort and performance and stiff enough to help with the reduced suspension travel. If there was a criticism it would be that for some, the ride height would be a little too low.

The new design has a front rate of 318lb/in and the rear 233lb/in. The ride height has been raised by around 10mm which will give the suspension a little more compression travel which on the M1 model is welcomed for the rear.

The rear ride height of the prototype is 5mm higher than the production springs will be.
