"I think you'll find H-D's success goes a bit deeper than that.....
Nothing to do with marketing a product people want at a price they'll pay?"
Not much deeper. Their bikes are mostly 1938 technology chrome plated and polished. I was told that a very significant fraction of HD revenue comes from the sale of other than motorcycles - hats, jackets, "accessories" , etc.
I grant that HD are marketing masters - making people want bikes that were eclipsed in quality and performance by the rice burners and euro bikes decades ago (IMHO of course). Go figure!
I dont think that Bell will be going away soon. If you havent tried the 407, give it a whirl - a most impressive helicopter.
