Today's guest blog post on the advantages of choosing a smaller bike over a larger one got me thinking about smaller bikes for an upcoming TAT trip. The more I think about it the smaller the bikes I'm looking at are. I started out thinking F800GS, then G650GS Sertao (which is surprisingly heavy), then maybe an Xchallenge ... now I'm thinking DR650 or even smaller. Anyone done the length of the TAT on a small bike? If you've done the TAT, what problems did you run into with the size of bike you chose? Has anyone done it with one of the big adventure tourers?
