I weighed 225 when I first got my ZX6r, and rode it until 270lbs when I sold it. I had it VERY STIFF by the end. I had maybe 2-4 lines showing on my forks and it fully clicked out on top; same with the rear shock. Now at 300lbs, my 14 as soon as I bought it, I got my wrench and flathead out and did the same. I had the zx6r on the track and it railed, but it needed SAG set, but I never got that done. My 14 feels great, but sometime I'd like to set my SAG. I dialed it in a little bit with a buddy of mine, but it was hard with no spanner wrench that would fit mine, so I had to buy a certain one from drag specialties and I have yet to use it yet. I just haven't gotten around to setting the sag on my 14 yet. I'll have my 14 at Mid-Ohio next summer having some fun and I can't wait!
