There was more at work here than genetics, of course. There was price. I got the Norton, nicely discounted, for around $2,400 while the R90S sold for a then-astounding $3,430. In mid-’70s currency, a $3,430 motorcycle sounded to me about like a $30,000 motorcycle sounds now. Prohibitively expensive. You had to really, really want one. But several of my friends, who were young and underpaid like me, scraped the down payment together, took out loans, and bought them. They just had to. BMW and Hans Muth had given them no choice.
