i was told you can't buy the bikes at the show. probably there will be other stuff on sale. probably a good job i can't buy a bike at the moment because i would and i can't afford it yet (or at least i can't afford the one i really want yet)
I went last year and must admit it I was'nt that blown away by it, but this year is bigger and better so it should be more fun. Just don't get there too early as you might be the only one waiting on the gate.
