Scooter Compression Kits Compression Kits are required when you are using threadless forks.
The 3 main types of compression kits available are:
SCS (Standard Compression System)
An easy to install clamping system that provides an external component to clamp the bars into the top and bolt the forks into the bottom. With this type of compression kit the slit on your bars will need to be cut off.
ICS (Inverted Compression System)
A starnut Installed in the Bars and a compression bolt is then screwed up through the forks into the starnut.
HIC (Hidden Internal Compression)
A starnut Installed into the Forks and a compression bolt is then screwed through the headset into the starnut located in the forks. This type of compression kit is for oversized bars only.
