Hi Andy, I have a 2005 FZ6, I have put on 20,000Kms and counting in 18 months and this bike is awesome.......seating position is comfortable.......Yamaha says this bike is not for the novice and I would agree that it does have alot of power but once you get used to it you will enjoy, It can be a bike you will keep for a long time and not get bored with as the power is there if you want it, factory suspension is a bit soft so you may have to adjust the rear shock like I did....depending on your cornering ability?
I haven't ridden the Kawi but have read alot and the FZ6 is by far a better bike in my opinion.
Good Luck on your course.....definitly a good idea!!
