Some of the 675's high-speed handling woes are inherent to the bike's geometry, but a lot of the trouble comes from improper spring rates and damping ranges. So I sent the fork and shock to Dave Moss of Catalyst Reaction Suspension _(www.feelthetrack.com) _ to be rebuilt to suit my needs. Dave raced a Daytona for three years and happens to be British, so he was the obvious choice. Re-valving the fork and changing the spring and shim stacks on the shock cost $1020 plus shipping, but it was worth every penny. I've never had a bike's suspension professionally tuned to suit my weight and riding style before, and the improvement was dramatic. In back-to-back before/after track days at Buttonwillow Raceway with The Track Club, the bike felt more stable, tracked better and had lost much of its mid-corner twitchiness. Perceptions aside, nothing says improved like hard data, and from one weekend to the next my lap times dropped a full 3 seconds. The Daytona's chassis isn't completely dialed-in, but it's getting there.
