I plan on making the trip to motorcycle Mecca (or Messe, the later being German for "shows" of sorts) in Cologne, Germany next year. Made the one back in 2010 as well. I'll be sure to bother the Triumph folks specifically and post it on the site so that all can partake. My apologies for not doing that the last time.
Oh, and you are correct! While there are various motorradaustellungs and motorradmesses in Germany, the Intermot occurs ever 2nd year, and only in Koeln (aka Cologne). I used to think that it was in Hanover, or in Munich (aka Muenchen) on the other years, but haven't been able to locate any information that might support that theory...specifically for the Intermot, that is. There are other shows though, but not as large, supported, or well known.
If anyone's interested in seeing what's out there, just navigate to Google.de, and do a search on either "motorradaustellung" or "motorradmessen" and find a page to push through Google Translate to convert the page to English.
