yep, gotta agree with scott, my zzr600 had the same shock (hmmm ohlins with a longer spring)and fork springs (spacers etc) setup AND muzzy 4 into 1 as troys bike (and dean thomas's).
my best was about a 1:50 odd on that bike at the creek. i'm no "A" grade road racer tho
compared to todays weapons it would be a heap of shite but compared to a 93-94 cbr or fzr/yzf it was a lot closer to being the best bike out there. certainly had the best engine, it was after all a kawasaki.
