1977 Kawasaki KH400 A3. 3 cylinder, 2 stroke street machine.
One of the smaller triples, but the frame in the background is the start of a bigger brother: 1975 Kawasaki H2 (750cc triple cylinder, 2 stroke badassery... long term project). I also have a Suzuki GS550 workhorse, and a 1988 Ford Festiva with over 1/4 million miles on it, and still gets something around 40mpg on the freeway.
