Basically gave my mate a quick shot of the bike, he lost control and crashed into a metal fence. Bike wont go back down into neutral at all. When I start it with clutch in, take off in 2nd or 3rd the back wheel locks up when going back down the gears. Hopefully taking it to garage tomorrow but any thoughts and whats the worst it could be and cost (£) to repair. Also have bent handle bars, leaking front caliper, cracked helmet and I'm hoping the front forks are not bent.
