Well done, Nelly.
I roll out in just about any weather. I alway say that the only thing that forces me onto 4 wheels is ice. I accidentally broke that rule last week. It's a bit scary, for sure, but it's not all that bad. Just stay smooth and verticle. Of course I was on the super light XT225 with knobbies.. so it's a BIG difference to be sure.
I do want to get studs for the XT and some good dual sport rubber for the fazer next winter. Maybe even studs for the fazer?? nahhhhh.
Oh, and you mentioned getting/building a hack. GREAT IDEA. I really want to do that myself. If only I could find a way to ride in the sidecar when it drops below 20F / -6C.
