Rokon 340

Brought out in the mid’70s, the Rokon was supposed to be the answer for those of us who hated to shift. All versions of the Rokon were very heavy, and loved to plow straight-on ahead, even if you sort of wanted to turn at the time. To start the big Sachs engine you had to tug at a rope-starter, which took a strong arm and an even stronger patience level. It came poorly jetted, and when it loaded up you would rip half the calluses off your hand before getting things spinning.

We talked about the belt drive earlier, and the less said about this the better. The thing was fast and had disc brakes to slow it down. Sadly, they worked intermittently, and the master cylinder often boiled over, leaving you with a lever that came back to the grip and a corner that rushed up to meet you. Gearing down was impossible with the torque converter, which meant you free- wheeled into turns and down hills. Spooky.
