I remember the K models. I can tell I am getting old when I read people calling sportsters "chick" bikes. What a crock. Back in the day the biggest bike, except for the Harley 74, was a 650, 500 being average. I rode Harleys, all of them 74 pan heads(bored out to 80) for years and if I had the money I would buy another one now. Sportsters were considered "the" bike to own when I was young, after the K model came the 883 and every MAN wanted one, at least the ones I knew. I consider a 900cc machine to be too big for a beginner to start out on.
Speaking of squirely handling bikes, I put a 61 cu inch knucklehead in an old Indian scout frame, for those of you who might know what that was, and it was one he** of a bike. Never dropped it, either on purpose or by accident. Can't say the same for a couple of my old 74s though. Most of my buddies rode 650 BSA or Triumphs, no one would have dared tell them they were riding "chick" bikes in a derogatory tone, I can tell you that!
