In my opinion, ICS can be just as good as SCS or HIC if done right.. But addict failed to do that. Their ICS kit blows. I traded the forks for some Declare IHCs so I could use standard sized bars.
Basically, you're gonna need a HUGE allen key (that they don't send you) and the bolt goes all the way to the top of the star nut, and screws into a special 3/8" threads 1-1/4" starnut (larger threads than standard size, not compatible with other ICS kits). AND it comes loose in one jump without threadlock or plumbers' tape.
Scooter companies need to start fucking deciding on ONE style of compression. The whole two sizes of bars, two sizes of forks, three types of compression, hundreds sub-types of ICS is getting annoying.
IHC > all.
