The Yamaha RZ350 was a twin, two-stroke Road motorcycle produced by Yamaha from 1984 to 1985.

Overview[edit | edit source]

Yamaha RZ350 , LC/YPVS in the UK, is a motorcycle powered by a twin cylinder two-stroke engine, reed valved 347 cubic centimeter engine. The bore and stroke are 64x54 mm. It produces 30.4 ft·lbf of torque at 7500 rpm. It came out as the RD350L/C in non-U.S. markets in the 1981 model year. The L/C model did not contain the "powervalve" exhaust port device available on the U.S. model RZ350's of 1984 and 1985. It was the evolution of Yamaha's popular and well known RD350. Production was carried on into the 1990s and a variant of the engine is still produced and used in Yamaha's YFZ350 Banshee ATV.

RZ350 is now a sought after collectors bike, due to it being the last road going two-stroke motorcycle in America. It is also raced extensively in Vintage racing leagues, as well as its own racing leagues, often dubbed "RZ cups".

A true milestone sport bike, the lightweight 350cc 2-stroke was offered in white/red and as a Kenny Roberts signature model, as shown here.

Engine[edit | edit source]

The engine was a liquid cooled twin, two-stroke. A 64.0mm bore x 54.0mm stroke result in a displacement of just 347.0 cubic centimeters.

Drive[edit | edit source]

The bike has a 6-speed transmission. Power was moderated via the wet, multiple-disc.

Chassis[edit | edit source]

It came with a 90/90-18 51h front tire and a 110/80-18 58h rear tire. Stopping was achieved via double disc in the front and a single disc in the rear. The front suspension was a telescopic fork while the rear was equipped with a swingarm. The RZ350 was fitted with a 5.28 Gallon (20.00 Liters) fuel tank. The wheelbase was 54.53 inches (1385 mm) long.
