Just got back from a test ride to Mt. Baldy Village.
On the freeway, the forks handled the small bumps with ease, much quicker action with less feedback to rider. On the big bumps, usually seams in the concrete that expanded and pushed up, it was less of a pogo stick action, it would compress quickly and rebound smoothly. They work like a good set of forks should. The rear shock is the weak link that needs to be addressed next.
On the twisties, the front was more predictable which inspired enough confidence for me to push myself a little further. The small bumps that were negotiated while leaned over for tight turns were handled quickly with smooth rebound. I have to set the sag though, it needs a little more. The front pushed slightly on a few turns, but it could've been a little dirt that was hard to see; we had light rains yesterday, so I expected dirty roads.
Also, there's less dive under hard braking. Hard braking on light bumpy roads are more controllable with less tendency to lock the front.
I'm not the best test pilot on 2 wheels; XRMikey could give a better description of the handling improvement with the Gold Valve kit.
