Description
Compression/Contra Spring for GY6 125-200cc Engines
This contra spring is made for GY6-type engines between 125cc and 200cc. By holding a lower gear ratio for a longer stretch, it helps with hill climbing and quick pickup from a stop. It is one of the GY6 150cc scooter parts that can noticeably sharpen how your scooter responds. Riders who want stronger acceleration and a more efficient feel from their scooter should find it worthwhile.
Improved Acceleration and Response
This spring raises the side pressure on the CVT belt, which cuts down on belt slip. When you open the throttle, the downshift should come in more quickly. It is made from heat-treated steel so it keeps its spring rate when temperatures run high, which supports consistent performance.
Installation Notes
Swapping the contra spring is simple, since it takes the place of the driven pulley spring. The spring carries a lot of tension, though, so work carefully. Use a clutch compression tool to hold the spring under control while you remove the large clutch nut.
