Sure, it may be decades older than yesterday's RS250, but the elemental simpicity of this 1980 Yamaha TZ125 and racing heritage visible at a glance, just as it was with that bike. The TZ125 was the successor to the earlier, air-cooled TA125 and was an over-the-counter racebike. Just add talent.
The tiny, liquid-cooled two-stroke put out 30hp, good given the displacement and even better considering the claimed 159lbs it needed to move. If I had one, I'd weigh more than the bike... With a more appropriately-sized jockey at the helm, speeds of nearly 130mph were possible. The rest of the package was pretty exotic as well, with a dry clutch, six-speed gearbox, and disc brakes both front and rear. This particular example even includes twenty-year-old safety-wiring...
