Yamaha YDS1/YDS1M brochure

In July 1959, so nearly 50 years ago, Yamaha started with the production of the YDS1, the first real Supersport Yamaha with twin carburetors.

Very optimistically, Yamaha talks about "100 mph plus", a speed that needed some years more to acieve with the first "open" specification RD250's. But the chrome fenders, flashy colours, headlamp with the large round speedometer that was kept basically up to the YDS5, a flyscreen to protect you from insects (in those years there were no full helmets, remember) made it a real eye catcher. The YDS1 was only exported to the USA and Australia as far as I do know.

Even more rare than the YDS1 is the Scrambler, or YDS1M. This model never got an official Modelcode. The YDS1 is 150, YDS2 152, YDS2M 154, etc. It was always assumed that Yamaha only produced "kits" to convert the YDS1 to either Scrambler or Roadrace specification. But I got the confirmation from Japan (and the brochure proves it as well) that the Scrambler at least was produced, ready to go, but in very small numbers.

Maybe it is worth to have a look in West Slauson Avenue, Los Angeles, the old address, to see whether there is still something lying around in an old warehouse..!
