I rode the FZ-09 at Willow Springs Raceway this last Sunday (11/28). There was a suspension tuner on site, and for $50, they adjusted the suspension every two sessions and dialed in the forks, shock and steering damper. By the afternoon, I was using all of the tire edge to edge and feeling very comfortable on the bike. The quickshifter and auto-blipper allowed for clutchless up and down shifts without unsettling the bike. By far, that was my favorite mod. The bike had plenty of grunt. More torque than a stock R6 with a little less top-end. In other words, I had plenty of power on tap that I still couldn't use, especially since we were on the more technical Streets of Willow track.
I'm looking forward to my next track day to build upon a great base set up.
