Worsham and Biek got started repairing, restoring, and tuning vintage, pedal-type mopeds through Biek's company, Motion Left Mopeds, a manufacturer of aftermarket performance parts for vintage two-strokes.
[2] The company's first model, the Halcyon 50, was a hard-tail motorcycle with a long, low tank, sprung seat, and wide handlebars, and 6-speed gearbox.
It had a TIG-welded, rigid, double-cradle tubular steel frame, based on the Norton Featherbed.
[6] All three models share the same "featherbed" style double-cradle frame, and proprietary leading-link front suspension.
Using the same engine as the Halcyon and Phoenix 250 models the Gryffin was designed to handle the occasional dirt or gravel road.
Current owners of Janus motorcycles were given an early preview and opportunity to purchase one of the first ten units produced through an auction format.
The engine features electronic fuel injection, four valves operated by an overhead cam, and dual exhaust.
