I looked at catalogs up to 85, and you're correct. I thought there were two separate lines classified as Sport Touring and Touring. How did they fare so well when other manufacturers had been using cantilevers for years? I know I'd be a little nervous cresting the top of a hill fully loaded, with the 600 sidepulls on mine. I am not saying sidepulls are bad, but they have their limits IMHO.,,,,BD
