The base model of this bike is something most people are familiar with – the step through Honda Cub, what James May once called the greatest machine ever. But in the late 60s, Honda was worried that scooters were losing popularity. Their solution was the Roadster Kit, which would completely change the CM91.
This bike is one of the rare examples equipped with the kit, which included a larger gas tank, custom steering neck, handlebars, triple clamps, seat, fender, and plenty more…all for $50. Unfortunately, the entire thing was cosmetic, so you were still stuck with 7.5 horsepower. For more on the kit, check out this article from the AMA Motorcycle Hall of Fame.
This example (VIN: CM91A138434) has just over 1,000 miles and it’s the only one I’ve seen in all white. The seller says that it’s a strong runner/rider that has some patina, “nothing out of the ordinary to be expected for a non-restored vintage bike.”
