I've been taking my GPz550 for some track days, and rather than upgrade to a new bike, I'd like to spend some to upgrade what I've got a bit. At least spend a season on it. (Though I've been eyeing a Ninja 300 or SV650)
Maintenance has been all taken care of, but what next?
What suspension upgrades would you focus on? I have Racetech front springs already, and I'm looking into emulators or anti-dive block off plates. Is there a rear shock you'd recommend?
What tires are people running on our 18" wheels? Are people changing over to 17" wheels from some other bike?
Are you racing in a series? If so you need to check out what rules they have consider them in your upgrades. Corey Clough (think thats how he spells it) is a member on here and has a gpz 550 that he has raced. i would search for some of his threads.
