I was reading some stats on my bike today (2003 CBR f4i.) and whilst I'm no speed freak, it's obviously a quick bike, it just wants to go.
I would say, to my mind, it's stupid fast and I always know when to back off but it gets to that point very, very quickly.
Basically, stats are this, 0-60, 3.17 seconds, 100, 6.65 seconds. Top speed in 1st gear, 72mph.
Not the fastest bike in the world by any means but I can vouch for it being almost mind bendingly fast (IME). Way faster than I'll ever likely need or go. 600CC puts you in supercar territory, or beyond in some cases.
It did get me thinking though, my bike is an almost 20 year old 600. I have difficulty understanding how a rider can even hold on to a modern, sportsbike, when the taps are opened, like a CBR 1000RRR, or BMW's equivalent, the S1000RR.
Those kind of bikes must be time machines.
