Next time you’re on the road, take a survey. I bet most of the motorcycles you see — and hear — will be Harley-Davidsons. The speedy sportbike rider spends a thrilling hour every Sunday or so on the road or track, but it’s the Harley crowd doing the daily commute, the cross-country vacation, the national rally. I’ve owned a dozen Harleys myself, the first a 20-year-old Big Twin I bought when I was 17. I’m 81 now, and when I ride my vintage 1970 racing Harley to the local casino, folks jump out of their motor homes to take its picture (it’s painted in a flag pattern, red, white and blue).
