I remember trying one of those Kaw 750 back in the day, it was a buzz bomb, fast once you got the revs up, almost too fast. Ring-ding-ding-ding. I always liked the low end torque anyhow. It still makes me drool when I hear a BSA thumper, like a 441 or single 500.

I suppose there will be a few of the young bucks that will be interested in the antiques, if only for what they did do without the technology, but probably not many. Just for info, the Germans were making the Jumo inverted V engines with 1400HP fuel injected magnesium engines in 1939 for the Stuka, imagine that. And they hand cranked the flywheel to get it started. Next thing they will be manufacturing motorcycles with large 3D printers.
