I've always wanted a true "all rounder". This is it - well, almost. The only real vice this bike has is the headlight, which is truly pathetic. My Honda 125 scooter is miles better! Also, the bike is a bit on the heavy side, and the fuel consumption is a poor (in my opinion) 42-45mpg. This compares unfavourably to the K100RS I had, which easily averaged 52mpg while delivering similar performance.
If only Yamaha had used fuel injection.
Finally, at 6ft 1", I find the screen too low for comfortable long-distance riding.
As far as quality goes, I've never risked riding it in the winter (unlike the BMW).
