EVO GP Slipper Clutch
You have seen pictures of it since 2010, and now they are available! It comes with a 40 tooth basket, plate set and clutch cover.
Its unique “spoon shaped’ Fin basket causes a progressive internal heat extraction from the clutch center. In addition to the clutch being a very small size making it much lighter, the most important feature of this clutch is the raw material: alloy steel, whose hardness removes the wearing effect among its parts which results in an incredible life time and increased value. But as always, it just looks dang cool.
The new Evo GP slipper clutch has been designed using the “ramps and spheres” patent, as well as the superior technical ability that STM is world famous for. Equipped with a 105 mm diaphragm primary spring, the new Evo GP slipper-clutch applies Evoluzione technology: diaphragm primary springs, available in different weights.
NOTE: Tool UTL-0030 is Required to Properly Torque this clutch
How the springs work:
The primary and secondary springs are mounted in such a way as to guarantee a preload which generates an initial resilient spring force.
How the primary spring works:
When the lever is actuated, the preloading position of the primary spring is varied and reduced. The spring returns an elastic force of contrast to the action of the lever.
How the secondary spring works:
The torque generated by the rear wheel tends to raise the drum. The secondary spring is compressed with respect to the initial resting position and generates an elastic contrast force.
