Sorry to hear about about your problems with the Rokon.
I owned a 1969 Rokon for number of years before getting a TW. They are unique machines and well suited for what they were designed for, which was to go places that no other motorized vehicles could go and for dragging dead animals out of the woods. While the newer ones like yours are certainly much more civilized than mine was, they are still basically an obscenely overpriced large mini-bike with a lawnmower engine. I had to chuckle when you mentioned that yours had a speedometer. Mine topped out at about a fast walk.
The first time that I took mine out for a serious off-road ride, the rear drive chain came apart into three pieces (the bike was already 30 years old when I got it!). I just stuffed the broken chain pieces into a jacket pocket and rode the rest of the day using only the front wheel drive. Much like a TW, if you recognize what a Rokon was designed for and don't try to make it into something that it isn't, then it will perform reasonably well. If you expect it to be a reliable dual sport motorcycle, you will be sorely disappointed. I kept mine for about a dozen years, but never rode it much. It was agonizingly slow and just not that much fun to ride. I always encouraged potential buyers to ride one before they bought one, as they are definitely a specialized type of bike.
If you haven't found it yet, there is a pretty active forum for Rokons at: Delphi Forums Login*-*Welcome! Please log in.
Don't expect much support, or sympathy, from the factory unless they have improved their customer service since I owned mine.
Best of luck,
