In the 1980s, tightening emissions requirements started to kill off the two-stroke motorcycles we knew and loved. Yamaha’s last gasp was the RZ350, which was able to sneak through thanks to the industry’s first inclusion of catalytic converters integrated into the exhaust system. US models were offered in 1984 and 1985 and were specifically marketed as Kenny Roberts replicas with the legendary “speedblock” livery and Kenny’s signature on the front fairing.
Note the YPVS acronym on the engine: that stands for Yamaha Power Valve System, a computer-controlled valve that could adjust exhaust port timing. This enabled increased torque at low RPMs while maintaining horsepower higher up in the rev band, resulting in over 40 horsepower at the rear wheel. There wasn’t much in form of competition for the RZ in the mid 80s, and Cycle World called it a ‘perfect 10 on the fun scale’ when it was their cover bike in July of 1984.
Estimated production of these bikes was around 20,000, 9,900 of which were built in 1984.
During his ownership, the seller has covered roughly 500 miles. The odometer shows 226 miles (and the trip meter shows 70, which is what the bike has covered since a complete engine rebuild). The chassis has roughly 25,750 miles.
