A 1000rpm spring will go into a higher gear sooner than a 2000rpm spring.This NCY 1500 rpm compression/contra spring will fit:Yamaha Zuma 2T 50ccMost Minarelli applicationsSpecifications:1500 RPM Compression SpringWire Diameter: 4.0mmInner Diameter: 44.0mmLength: 108.0mmAbout NCY:NCY stands as the premier provider of aftermarket performance components for leading scooter brands such as Honda, Yamaha, Genuine, Vespa, Piaggio, SYM, Lance, KYMCO, and GY6/QMB powered scooters.
