Top gear 4k RPM is 60 MPH. Not that I don't use the upper ranges for the twisties and racing, unless you normally cruise and 100, why would you normally use 6-7k?
Its rare for me not to see triple digits when on the FZ1. Not saying I ride there all the time but I like the way the bike feels and performs in the higher revs. Also my gearing changes the equation, I get there even faster! Yet i still rarely use 6th. Its not for everyone, as i learned from this thread.Even with 16/47 I rarely find myself using 6th gear. The bike seems happier in the higher rpm range, it sounds better, performs phenomenally and shifts more smoothly there.
