Robert Korpi was also owner of Rokon International from about 1976 to 1990 Rokon was founded in Vermont by Orla Larsen in 1963 to sell the Nethercutt Trail-Breaker, a two-wheel-drive motorcycle invented around 1958 by Charlie Fehn and built in Sylmar, California.

In 1974, Rokon produced the RT340 TCR Automatic motorcycle, using a snowmobile-type Salsbury CVT, rear wheel drive only, and dual disc brakes.

Riding on loose surfaces is sometimes complicated, as rear wheel breakaway does not cause telltale changes in the engine sound.

However, most other riding is intuitive and sometimes much more convenient as the automatic avoids engine stalls and other problems with gear selection.

Despite low front wheel weight, about 43%, it had trouble pulling wheelies, a problem for Enduro riding.
