FST front end
Went out for my maiden voyage with the new lowered FST Progressive front end and Pro Action rear coil overs. The front is firm with no diving on hard braking and my bike corners like it is on rails. The only drawback is the left fork is a bit longer with this kit, Progressive say's it's supposed to have a slight preload. So now every time you pull the front axle you have to contain the left fork with a ratchet strap and take off your front fender.
