Built by Rusty Bolt Garage, this is a restored example of a tiny street scrambler that introduced Yammie’s ‘boost ports’, which helped power and torque due to an impressive increase in scavenging of the engine.
The boost ports helped the tiny 124cc put out an healthy 15 horsepower, yielding a top speed of about 80 miles per hour. For more on the AS1C, check out this profile from Motorcycle USA, who call it a memorable motorcycle. Or, head right to Rusty Bolt’s page on this specific build.
This specific AS1C (VIN: AS1301775) has been rebuilt to basically stock specs, though it has K&N filters, LED turn signals, and a repaint in a non-stock color scheme.
