if you like the feel of a bike then by all means buy the one you like, but did anyone see the crash on roseville bride a few months ago? sorry but i have to mention this... i know Doctor probably did. There were 2 body bags about 100-150m apart. Everyone thought two people had died but it turned out that one bag was for the body, the other for the head. The guy was go so fast he was decapitated once he hit the side of the raling.
anyway im sure you've heard heaps of stories like this, but its just not you that you have to be worried about. Its other wankers in cars who take no notice of you on a bike and if they switch lanes it'll be too late. Anyway bikes are pretty cool and they kick the crap out of cars, but of you want a bike i'd say gp for a peewee 50 . Those Ducatis though are VERY nice indeed.
