Boy, did this bring back memories! My first bike was CL K5, differing from this only in color. Mine was green and white.
The good: it would carry two of us over just about any hill in 5th gear.
The bad: it was turning 1000 rpm for each 10mph in high gear. We put a lot of miles on that poor beast. Sold it to help make the down payment on our first house.
Thanks.
