Greetings Twosheds, and welcome to the Foc-ers! Can't go wrong with an early Fazer 600, awesome bikes.
As for the Fazer........
I never buy the same thing twice, unless it's really worth the money. I'm now on my third Fazer 600!!
Comfort:- I did 30k/year on mine for the first 3 years!
Power:- 90ish bhp on British roads is enough!
Torque:- low down and punchy for a 4 pot
Economy:- Personally I've done 73mpg, but normally 50 + mpg and 200 ish miles to a tank.
Handling:- The most neutral handling an forgiving bike I've ever ridden! (and theres been a few)
Spares are in the abundance, and cheap as is the knowledge from us Fazer perverts on here!
It's a no brainer really, the only problem is, once you've had a Fazer, any other bike you have in the future will be compared to it, and will never tick as many boxes!
