Compression Spring for Genuine Buddy and Blur Scooters
This compression spring, also known as a contra spring, is designed for use in Genuine Buddy 125, 150, 170, and Blur 150 scooters, as well as various Chinese GY6 engines. It plays an important role in managing the pressure needed to engage the belt in CVT transmissions. This spring is one of the GY6 scooter parts that helps determine how quickly your scooter shifts from low to high gear based on RPM adjustments.
Functionality of Compression Springs
The primary purpose of a compression spring is to provide the necessary pressure for the CVT system to function properly. A 1000 RPM spring allows for earlier gear shifts compared to a higher RPM spring like the 2000 RPM variant. This can lead to improved acceleration and responsiveness in your scooter's performance.
