you know, the cost of your Duc vs the cost of your CBs just goes to show that spending $$$ on motorcycles is really an exercise in demonstrating the rule of diminishing returns. I mean, you can buy a CB, or any other 20-30+ year old UJM, for next to nothing, spend a grand or so getting it rideable and reliable, not to mention cool, and you're out say $2-3 grand and have a badass bike that you can ride cross-country over and over again!
Or, you could blow $30,000 on a Harley and barely ever put the rubber on the road, or $15k+ on a Duc plus tons of $$$ on upkeep, and still not get a whole lot more enjoyment in the end than the guy that buys a cheap used bike, makes it his own, and rides the hell out of it.
