Yamaha XS1 650 Motorcycle - Street (1970-1971)

The Yamaha XS1 650, produced from 1970 to 1971, was Yamaha's first four-stroke motorcycle, featuring a robust parallel-twin engine. This 653 or 654 cc engine was a four-stroke, air-cooled, SOHC unit with two valves per cylinder. Its bore and stroke measured 75 mm x 74 mm, delivering a claimed 53 bhp (40 kW) at 7000 rpm for both the 1970 and 1971 models. The inaugural 1970 model, the XS-1, was typically available in candy green with white tank stripes. For 1971, the model evolved into the XS-1B, a mildly modified version. Changes included a different compression ratio, revised carburetor jets, adjusted ignition timing, and different spark plugs. The XS-1B was also approximately 13.6 kg lighter. Both models were kick-start only and featured twin leading-shoe drum brakes on the front. FAQ:
