I went there a couple years ago and had a good time. It is amazingly large and is really more that a consumer product event. About half the event is component suppliers promoting their businesses to the industry and a lot of emerging market manufactures looking for a way to enter the mainstream first world markets. You see a lot of knockoffs of 1970's Honda small displacement products. Considering the stuff Honda made back then was pretty good, its probably a good approach for a new company. (I saw some nice examples of Honda CT70 Minitrails which would still be fun to have!)
The are a lot of accessories and clothing on display as well. I saw some pretty cool helmets including a nice one from Bell. (but with the colors inverted... black with a white stripe) I am a little temped but it is a little too expensive.
And of course the is the usual festival food when its time for a break. A Bratwurst with kraut and a beer in my case. Perhaps not as Italian as some other option but it was good!
Along with the normal range of new 2012 motorcycle products there was a nice selection of scooters, custom bikes, race bikes, and vintage motorcycles.
