Its not TRAIL............its Trials, completely different, its a Trials bike, Bultaco, Ossa, most motorcycle manufactures sponsored trails competition, very popular in Europe and Slavic countries.........sorry but someone has to correct you ! :)
Development had Nothing to do with Beamish uk. till it failed to sell well around the world. Beamish UK then started too Mod them to make them a better trials bike. .
Its not a Beamish its a regular RL250. It was uncompetitive and Suzuki ended up selling the remainder to Beamish who changed out the frame and fixed the engine..
