Yamaha sold the RD60 in the U.S. from 1973 to 1975. I've not been able to find any figures on how many they sold, but you don't see many for sale at any one time. Powered by a 55 cc two stroke, the little engine that could makes 4 smokey horsepower and redlines at 10,000 rpm. Most of that power doesn't come on until 6,000 rpm and it's said that on level ground, you can hit 50 mph. Yamaha claimed at the time you could achieve 188 miles per gallon at a steady 18 mph. With a 2 gallon tank, you can probably go for months before you need to fill up at the station.
The RD60 was a step up from a scooter or mo-ped, offering a real clutch and five speed transmission with a typical motorcycle shift pattern. It came with full electrics including head and tail lights and turn signals. This bike is missing its rear fender that would have the tail light and turn signals. Might be a bit of a challenge to source replacements as well as more exciting to ride in traffic. Do you think any of today's drivers know the hand signal for stop?
