some of you guys never cease to amaze me (I mean that as a compliment BTW); it would NEVER have occurred to me to ride a Versys in the snow! LOL.
The only proper/safe way would be tire studs (anyone watch that episode of "Jesse James is a dead man" ?) like the ice racers use. i would imagine tire availability and clearance would be issues on a V.
I ride my offroad bike in the snow every year with just regular knobbies and it SUCKS! Unless you want to crawl forward with both feet down, plan on crashing often. I can't even imagine doing it on a streetbike with regular street tires.
