I rode a K1 once on a saturday. I had defended my PHD on the day before, and drank the devil's juice until i couldn't drink anymore.
I woke up saturday, and for the first time in 5 years, didn't have anything hanging over my head. I had a hangover, but nothing hanging over my head.
St. Paul BMW/Honda (long gone) was offering test rides of the K1 in May of 1992 (said so in the newspaper in the motorcycle section of the want ads. remember those?). I rode my 1971 R60/5 and said, "i'd like a ride." They said, "sure," and off i went.
My BMW references were an 1974 R90s and a 1977 r100rs (demos from my motorcycle shop days), but the K1 blew me away. WOW.
However, i was broke, unemployed, and soon to be homeless, so the furthest it went was a test ride. it was a great ride for its day.
