Rode it to Wigan Yamaha where they had both a Fazer 8 and an FZ1S to try.
If Yam had combined the thou lump with the Fazer 8 aerodynamics I'd have happily handed over both bikes and the requisite cash, however there's still that niggle...........
Fazer 8 looks more up to date, and the new version they've improved the suspension, the new fairing is incredibly stable at harumph speeds, and the increase in power over the FZ6, although not huge is noticeable and appreciated due to the way in which it's delivered.
HOWEVER
FZ1S it's 150BHP fer christ sake, and the one I'm looking at has an Akroprovik carbon pipe, so sounds the dogs, but at high speeds the fairing's on a par with my 6 hence buffet at significantly below the 8s harumph . But that acceleration, what a 'kin blast
Kinda guess where I'm going to be spending me cash ..................On tyres, fuel and speeding tickets
