Rode motocycles from my late teens through my 20s.
Started out with dirt bikes and then owned a couple of street bikes. In late 1977 I bought a KZ-1000 Ltd which was the fastest production bike you could buy at the time. Yes it was fast (85hp, ~500lbs) but it also was a very smooth, great handling bike. It became my main transportation when I lived in Tempe, AZ in the late seventies.
