Strange as it may seem, I have been toying with the subject of replacing a v max and an r6. Guessing some street riding , and some track. I think the z1000, newer version could be good for doing both, but a little frustrating on the track. Having said that, I know one of the uk magazine groups did do a couple of races on one and seemed to enjoy it.
The thought I came up with, was the triumph street triple. The handling is superb, comfortable on the street, lots of turn leverage, very sweet motor. All in all a great machine. Let me know what you think. This is working on the presumption that the naked aspect is important.
