One of the fundamental upgrades you can make to your scooter is swapping out the clutch springs for ones that will give you more acceleration off the line.

This set of Malossi Racing Clutch Springs come with three pre-hardened carbon steel springs, with high yield strength, that are
protected by a high heat-resistant paint.

This set is for use in a stock clutch with a Ø 107mm clutch bell. These springs are made from a 2.2mm wire and are rated at 5000 to 7000 rpm.

Note: It is also a good idea to change your clutch springs occasionally. It would not be good should one snap unexpectedly.
