My s1000rr is my rat bike. It goes everywhere.
I work with refrigeration, so I appear dressed in casual. I have two layers of sweat pants underneath my jeans. My jacket is a Gerbing's electric. The mosfet voltage regulator on our bike is awesome and keeps the battery at 14.5 volts, even at idle when heating a full electric suit. This "casual" dress is comfortable down to 20F. I have tested the full electric suit in the freezers at work at about -40F in front of the evaporator fans. Gerbings kicks ass.
I use Bates Police Tactical Boots with GoreTex and side zippers. Very comfortable and suitable for running. Warm in the winter, cool in the summer. These are THE best riding boots I have seen anywhere. The Bates "riding boots" are just a worthless fashion show for the Harley freaks. Go with the police version.
My tankbag has the mushroom type velcro due to our aluminum gas tank. I use an Eclipse Elite expandable tankbag, which is big enough to hold four gallons of milk, full electric jacket, groceries, or whatever. It kicks ass. I laughed and almost fell over when I saw the BMW factory "tank bag" purse.
For security, the s1000rr is garaged at home. Out of sight, out of mind. At work it is guarded by security, cameras, fenced, and I use a Scorpio i900 self arming alarm.
My favorite tires for ice and snow are the sticky Michelin Power or Pirelli Corsas as they stick like frog's feet. There's a trick to this...if the tires are heated above freezing due to friction, it will melt the ice below and slide. I have never found a Dunlop, Conti, or Metzler worth a crap in the snow as they slide like grease. Night and day difference.
