I'm in too - Thanks for the tailbag idea. I have the exact same bag and thought it was too big as well.
I rode a KTM950 in the 2006 and 2010 Alcan5000 TSD Rally. I entered the 2014 event with my Yam WRR. Most of the riders will be on twins or large singles. They have been warning me away from my 250 as they think it's too small to keep up during the liasons and might not be able to stay ahead of the chase trucks. I have a KTM 690R I could ride, but I like that little Yamaha and I find it pretty comfortable for long distances on dirt roads.
We'll have 14 hour days and I typically cruise the liasons about 75mph. But the speed limit is 60, and the WRR is pretty happy at 65mph.
and check out the itinerary.
So far the starting field looks like 18 cars and 49 motorcycles.
