I crashed my 98 Fazer a few months ago- new tyre, wet weather, following a mate on roads I didn't know... Pretty stupid really.
Anyway, I managed to snap one of the stanchion legs in half, the other was pretty bent, my tyre went through the radiator and needless to say the fairings and the like were trashed. Overall, not a pretty picture at all.
I was looking at a few options- buying a similar model with more miles off of ebay, possibly keeping the rest as spares after a few transplants... selling my bike and buying a new one... Even going straight to a manufacturer and getting a brand new Yamaha on finance. But in the end this Fazer was my first big bike and I simply couldn't part with her.
I got in touch with a few motorcycle breakers, and between the breakers and ebay I managed to sort out everything for about £400, covering the forks, bottom yoke, front nose fairing, radiator, fuel tank, headlight, clocks, front mounting bracket and a few little pieces besides.
So fix it, you'll love the experience and afterwards will feel even more confident on your bike, if that's possible.
