Optional Springs
Optional springs have been designed to allow adaptation of the M-10
suspension to your specific needs. The 140 lbs./in. optional front arm
spring would be used when very light load conditions exist, such as
operation on very smooth trails, in deep powder or by very light riders.
The 300 lbs./in. rear arm spring option would be used when high load
conditions exist, such as operation by heavy riders on rough trails or
very aggressive riding. The available springs for M-10 suspension are
listed below.
