ZX-6R (wish I could vote for it)
While I have always lusted for a ZX-7R (RR), I raced the ZX-6R and may have purchased the first one to arrive in Virginia in 1995 after the earthquake in Kobe (remember that?)
The bike was awesome, especially at the track. Everyone else was on Honda F3's. I put a pipe and jet kit on the bike, ran DoT's, and after I got my bearings racing, the bike was kicking butt at the track, stock body work and all. I am also proud to say that I got within 1 second of the track record for Summit Point (held then by a 750) on that bike with that setup, including me taking one corner in the wrong gear!
I never, never, never should have sold that bike. I ended up converting it to a Superbike just for the challenge of running against 750's. Flat slides, quick shifter, Marchesini wheels, slicks, Brembo Goldline front calipers, Ohlins rear shock, Race Tech fork internals. The 750's would pull me on the straights, but I'd more than make up for it (usually) under braking and with superior cornering.
I have to admint though...the 998R stole my heart.
