Brand new clutch push spring kit adaptable for vertical and horizontal Minarelli engine 50cc scooter with inner diameter 105mm, 107mm, 112mm clutch bell. The clutch thrust spring acts on the opening of the torque corrector, it influences acceleration and pick-up. Her force opposes that of pebbles. A thrust spring that is too hard will not allow your torque corrector to open correctly, conversely a thrust spring that is too soft will open your torque corrector more quickly.
