THE PERFECT FIT
Edge Touring Suspension
Edge Touring Features
Torsion Springs - Two torsion springs are used on the rear arm of the
ETS. Preload adjustments can be made by turning the rectangular
adjusters with a spark plug wrench.
Optional Spring Rates - Optional springs have been designed to allow
adaptation of the ETS to the varied needs of our customers.
The optional front track spring and the firm torsion spring should be
used if frequent bottoming is encountered during two up riding on
rough trails.
The soft torsion spring should be used for frequent one up riding on
smooth trails.
