I ran across an interesting thread that I thought ya'll (or at least a few) might enjoy reading. It's about "becoming an Army motorcycle dispatch rider" on underpowered, air cooled, drum brake motorcycles, not unlike the ol' BSA we love.
Nice! I have the same ski's, but not much snow here, it's gone in a couple of days! but I once tested them on my Matchless, together with the spikey tyres, and it works really well!!!
Wonder if the newer ski's are made from aluminium??
