True to my word (see below) I've been using the bike no matter what the weather gods have thrown at us. Yesterday we had gale-force winds and torrential rain, but I still met a couple of the lads for a ride. Mind you, when we got to Ballater and saw the snow above the town we did turn around and beat a hasty retreat.
I'm pretty pleased with the GS, I'm using it in weather that I wouldn't have ventured out in on the Bandit, so thats a bonus. And it looks better all covered in mud as well. I also discovered that wet grass doesn't seem to offer much grip, even for knobbly tyres, so I'll have to stick to the mudslide, as I affectionately call my driveway, for access to the house.
