The 636cc Kawasaki ZX6R is the best track bike on the planet.
Please don't misunderstand, there isn't a "bad" 600 class bike on the market. But after putting almost 2,000 riders on the new 2005, ZX-6R, at over 12 different tracks; every student who rode them raved about how great they work; many went right out and bought one. If there was never another advancement made in the class I would settle for the pure performance this bike offers to any rider, novice through professional.
That is a bold statement but I'll give you an example. One of our students, Leon Camier, who is a pro; and in fact won the British Supersport championship this year, came within 3 seconds of the absolute race lap record at The Streets of Willow Springs on a box stock ZX6R with DOT tires. Box stock, pump fuel, factory shock: zero modifications, OK, the lights were removed.
Just to put this in perspective: American magazine testers generally log in lap times on 600 class bikes 3 seconds slower than what Leon ran.
Leon, who is used to professionally prepared race bikes, had NO complaints about the 6R, he just rode it, loved it and never asked for a single modification or adjustment. That is quite a statement from both a pro and a champion.
Riding is what the 6R is all about. (Of course one of our staff, Will Eikenberry, is the absolute race lap record holder—guess what he was riding? Hint: it was green and had 636cc)
Red bikes are great, so are yellow ones and blue ones; but, if you are a track day rider, the green one is going to give all the performance you could possibly want.
Break it in, change the tires, go ride it; take a can of chain lube with you, that's all you'll need.
