It's loads of fun; being up close and seeing those guys run deep into turn 1 is pretty epic. The noise of the MotoGP bikes up close is indescribable; not like Top Fuel for example, but pretty awesome. As an event, I prefer WSBK; it's waaay more laidback, and bike riders get special treatment at the circuit (you can ride your bike around inside; even parking close to spectator areas) on Friday & Saturday; you can ride you bike right up to the fenceline. Whereas at MotoGP, you get treated like every other mutt, and have to park outside and walk around inside. Everything is much more serious, and geared to the corporate side. Obviously MotoGP draws a much bigger crowd over the weekend, so it would be more difficult logistically, but the vibe at WSBK is much nicer. Do yourself a favour & get down to Isola restaurant in Cowes if you can; all the Italian teams eat there, so you can potentially be rubbing shoulders with the riders. Fantastic food, great prices, top atmosphere, not pretentious at all. The wait staff weren't too shabby when we were there too... Get down there; you won't regret it. Wish I was going down, but I'll be there for WSBK next year.
