The bike found me. I had sold my last bike, a HD FLHS, in 1991 and was not looking for a bike at the time. The kids were small and I had had a close call on the HD that took the fun out of riding. One day in 1995 I was walking down a hall at work, in an area I don't get to very often, when I stopped at a bulletin board just to scan what was for sale. Right in front of me was an add for the Hondamatic and the price was only $600. I had always wanted one to use as a drag bike and thought this would make a good one. One phone call and a trip to look, had me dragging a non running, barely rolling 6000 mile Hondamatic into the truck. So far that's the only dragging I have done with it.
After a few repairs to correct years of neglect, it had been inside, I had it running. A new set of tires later, it was on the road. Guess what I found? That joy of riding that I had lost one day on the HD! Since I could have owned one of these bikes when they were new, it did not feel old to me. The styling and feel were what I expected, so there was no dissapointment. In my mind I was riding an almost new motorcycle, but without any payments!
Newer bikes don't have that same look to me. SOHC's have a timeless look and style to them that will never go out of date. The ease of repair is wonderful as is the availability of spare parts. Although to be fair, other than a few minor things to get it going, most repair items have been for normal wear and tear. Filters, tires, chain and sprockets, etc.
The better question would be, "Why Not SOHC4's?" They have so much in their favor over other bikes.
