My system is a kit that converts factory forks to air ride. Air controls the height / preload, will also have an option of an air adjustable remote reservoir and you retain the hydraulic circuit of the fork so you have the compression and rebound control as you would adjust your factory fork. In my testing i have ridden the twisties just as hard as i would with the standard forks and got to some pretty low lean angles. The kit is designed so there are NO modifications to the fork.
Pricing on the kit has not been finalised as yet Hectic, but as this is a kit that is installed into your existing forks its going to be a lot cheaper than a set of new air suspension forks.
Cheers,
Matt
