Well its finally time to upgrade, and hopefully ill be coming back from the dark side and onto a kwakka

The probelm im having atm is that even though i can afford to buy and full comp insure my ideal bike (03-04 ZX-6R), my parents will not let me buy it because they think the insurance cost is too high.... Im looking at around $7.5-8k for an 03 zx-6r and 1k to insure it for the 1st and 2nd years, and then down to $850 for the 3rd year. However, they would prefer me to spend $8k on an say an SV650, because the insurance is only $650.....i completly disagree because if i get a bike like an SV650 i will be bored within 6 months, they're more expensive off the bat, and they just aren't up to the standard of a ninja. So any suggestions on how to turn them around? And since ive gotta look at lower insurance bike, what are ppls opnions on the following bikes?:
- Z750: id prefer a faired bike but i have a soft spot for the zeddy, but is the seating position as sporty as a zx6r?
- CBR600F4i: I really like the later F4is, with FI, good looks, decent power and equipment its one of my favs
- older zx6rs: in comparsion to the later models, what are say the 00-02 models like?
Basically what im looking for is a mid-sized sportsbike, preferably with FI, with a decent amount of power and good quality suspension, so any suggestions and opnions are welcome

thanks guys
