Back in 1979, I was 21 and was at last earning enough money that I could afford to buy a new middle sized bike, and drew up a list of 'possibles'. Eventually I bought a Yamaha SR 500 but a close second on my list was a Honda CB400N 'Super Dream'.
The Super Dreams were very succesful, especially the 250 version which fitted in with the learner laws at the time, and was for many years was the biggest selling bike in the UK.
The 400 sold fewer as most riders who'd passed their test on a 250 moved onto 500/550 cc bikes, but it was still highly regarded and I remember a magazine saying that if BMW built a 400cc twin, it would be like this.
Being so popular meant that there were plenty of aftermarket accessories, with Rickman fairings and Rickman or Krauser luggage turning them into useful tourers.
Had I bought a CB400N, it would have ended up with a Rickman fairing and Krauser luggage, and I probably wouldn't have bought the BMW I eventually went touring on.
Many years later I eventually rode a CB400N (I'd ridden plenty of 250s), and I was very impressed by the wide spread of power and how 'together' the bike felt. Not buying one back in 1979 was probably the worst motorcycling mistake I've made, but that's life!
However, there's a postscript to the story - in the early 90s I was thinking about buying another bike and I came across a Honda CB400A for sale locally. This was the very rare version of the earlier Dream fitted with a 2 speed automatic gearbox. As I was commuting across town at the time the automatic appealed, but I thought it would be too restricting for more open road use. Found a picture of one and you can see why Honda thought a restyle was quickly needed:
