Went out for a ride last night on my uncles Z750 while he rode my bike.
I have to say, I absolutely loved it! Ok, so no wind resistance past 90, but I don't ride that fast very often anyway. But you can really throw it into bends, hang off much easier and lean it right over easier than mine. I nearly got my knee down last night without even trying. I want to have another go on a warm day, rather than in the cold at 9pm. It really filled me with loads of confidence.
I am hoping mine will get a bit more like that when I fit the new tyres. Some stickier, and round rubber might make it come to life a little more than the squared off touring tyres that are currently on it...
