I've not yet passed my test, but i'm 24 so DAC will get me on a 650. I'd be very interested in possible purchase, depending on the damage caused; mostly so I can learn how to fix these things!
Cat D on a bike this value is 99.99999% guaranteed cosmetic, though, so you should get a fair wack for it whatever happens. It might have to become a naked if it wasn't already, though!
EDIT: Ouch, just looked at your thread about the crash! Like I suspected, it's all the plastic that's gone... The nose is £300 a pop as I understand it, and the can and down pipe from front cylinder will need replacing too
Still, the tire didn't pop so the rear wheel and swingarm / shock are ok!
