Nice find. Lots of memories of those bikes. Some not so great. I had a 74 Honda 750four. Great machine. Traded it for a Kawasaki 900 Z1. Holy jeezus, hang on. Awesome power, but horrible handling to the point of mulitiple hi speed wobbles. I got pitched off into the desert once at around 80mph. Broken clavicle was the only injury. Waaay lucky! Went back to the Honda.
Years later, I had a Honda 900rr. Wooooot! Used to go out on Sunday mornings and just scare the crap out of myself with a huge grin on my mug. Alas, wife and kids brought an end to my speedy days.
