I shipped the bike RoRo from Germany to Hilfax/Canada with the support of Intime from Hamburg (http://www.intime-ham.com/) and had good contact with Mr. O.Kleinknecht
For the transport from Panama to Colombia (the Panamericana is disconnected there, because of the Damien Gap) I booked a ticket with Stahlratte (http://www.stahlratte.de/). So far quick contact be email and Facebook.
Faires and meetings:
+ Have been at the Intermot in Munich (typically in JAN/FEB), check the net
All major motocycle manufacturers, tuners and equiment makers are present. Good for basic information and flyers and booklets and some tech-talk.
+ Have been at the Touratech Days in Niedereschach (at Touratech HQ)
Great event with lots of useful information. Some big players have a booth. Check the Touratech website for the details and when the next annual event is scheduled.
