Description
Compression Spring for Genuine Buddy and Blur Scooters
This contra spring, sometimes called a compression spring, suits Genuine Buddy 125, 150, and 170 models, the Blur 150, and a range of Chinese GY6 engines. Its job is to set the force that keeps the belt engaged within a CVT drive. It is one of the GY6 scooter parts that influences when your scooter moves from low gear to high gear as engine speed changes.
How Compression Springs Work
A compression spring supplies the pressure the CVT system needs in order to operate correctly. Choosing a 1000 RPM spring makes gear changes happen sooner than a higher-rated 2000 RPM spring would, which can give quicker pickup and a more responsive ride.
