Hey mate, glad you're not too badly damaged for starters.

Can't really comment because I haven't had any high speed offs (touch wood!) but I have laid it over a few times when the tourances gave way on loose ground (you're right about the tourances on anything but bitumen). My brake and gear lever typically fold back or get wedged against the engine casing causing nasty gouges but that's the worst of it. The tank plastics seem flimsy so I reckon they'd bend out easily too - but that hasn't happened to me. Handlebars bend easily too with the sort of crash you had so that may give the impression that your wheel isn't running straight.

You should be able to see easily enough if your front wheel is buckled, but it is likely that your wheel axle may have twisted in the clamp. Maybe loosen off the front wheel (if you can find the right 14 mm Allen-key socket) and retighten. Once the axle is tight, then you can use the bounce technique to make sure the front wheel is sitting right before you nip up the two axle clamp bolts. Someone else could probably explain this better.

Anyway, I think these bikes are tougher than they look in terms of surviving a bush stack.
