KOSO Spring Slider Base with Ball Bearings for 50cc - FM014000

The Koso spring slider comes complete with base plate, spring holder and ball bearings. The outstanding design of the spring slider prevents spring wind up and distortion of the rear clutch compression spring that occurs when the rear clutch shifts in and out thus causing the spring to twist forward and backward.

Without the spring slider, the compression spring will eventually become relaxed and deformed causing the spring tension to change.  It is highly recommend that this part is purchased and installed with the rear clutch compression spring

• Comes complete with base plate, spring holder and ball bearings
• Prevents spring wind up and distortion of the rear clutch compression spring
• Recommended for use with the rear clutch compression spring

This is a torque spring base for 50cc Minarelli 2-stroke engines that will allow for smoother torque spring action through the use of ball bearings. This allows the spring to pivot and turn free rather than binding up.
