Have any of you ever seen one of these? It's called SnowJob and was sold by Advanced Recreation Equipment of Mountain View, California in 1973. The conversion is a twin track assembly that your motorcycle bolts into after removing the wheels and it looks like the chain is used to drive the tracks. The motorcycle tilts within the tracks which would give the front ski the ability to carve through the turns. From the coupon in the magazine ad, you fill in the blank and indicate what kind of motorcycle you have, perhaps they would make one to order.
Did these ever make it on the market? Did they ever sell? Have you seen one? The photos in the ad show a Kawasaki bolted into one so at least that one was built. I didn't find the company with a quick search so it didn't seem to make it unless it merged or was bought by someone else.
The conversion looks like it might have worked to some degree and the twin tracks would probably keep you upright. So, do any of these still exist?
