If your hands are getting cold during your winter rides, I can recommend these handlebar muffs. I bought a pair for my BMWs. The muffs only take about a minute to install and I just move them from bike to bike before I ride. They seem to be pretty much a universal fit product and it works on all of my bikes, although they seem to work better if your bike is equipped with plastic wind deflectors as they are contoured to fit over bark busters. The price is fair, they compact into a relatively small package for storage and I like the clear window over the bar control button area so that you can see where the horn and other control buttons are located.
