Overview[edit | edit source]

Yamaha broke into new territory by creating a 4-valve per cylinder engine in a production street bike with the 500cc, 4-stroke, twin cylinder TX500. In 1973 the TX500 appeared with twin overhead camshafts and two years later evolved into the XS500 which sold to the end of the decade, but never in large numbers. While it was a very innovative motorcycle much of its thunder was stolen by the rip roaring RD350.

Engine[edit | edit source]

The engine was a air cooled Air Cooled, Four Stroke, Two Cylinder, DOHC. A 72.9mm bore x 72.9mm stroke result in a displacement of just 498.0 cubic centimeters. Fuel was supplied via a double overhead cams/twin cam (dohc).

Drive[edit | edit source]

The bike has a 5-Speed transmission. Power was moderated via the Wet multi-discs.

Chassis[edit | edit source]

The front suspension was a Telescopic fork while the rear was equipped with a Dual shocks swing arm, preload adjustable. The TX 500 was fitted with a 4.0 Gallon (15.14 Liters) fuel tank. The bike weighed just 425.05 pounds (192.8 Kg).
