The main problem is I'm 6 foot 4 and weigh 15st and I tend to take a lot of the seat. I found moving foward towards the tank made it a bit difficult to change gear. I'm not worried about speed I like to see around me nor do I venture off road but I love all the little B roads we have round here as does the r, so I'll think about testing the Z sometime this summer (providing the current economic climate gets better and we both still have a job).
As always thanks for the wide range of advice.
