YAMAHARZ 250R 1984 - 1988

　　In 1984, the Japanese motorcycle manufacturer launched the Yamaha RZ 250R, a popular machine made for racing and modifications. The bike could have been modified with plenty of aftermarket for more power, better handling, and visual improvements.

　　The Yamaha RZ 250 was a standard motorcycle manufactured by Yamaha from 1973 until 1987 when it was replaced by the Yamaha TRZ 250. The RZ 250 designation was known in the Japanese and Australian markets and RD 250 in other regions.

　　In 1983, the British government changed the maximum cc for learners motorcycles from 250cc to 125cc. This modification in the legislation had been made due to the RD 250 model that delivered high-speed capability, so it wasn't a perfect machine for inexperienced riders.

　　In the visual department, the bike had standard features, such as a half fairing with a rectangular headlight and a medium-sized windscreen, a one-piece dual seat with a passenger grab handle, a dual exhaust system, and three-spoke lightweight wheels.

　　As for the power figures, the 1984 Yamaha RZ 250R had its soul brought to life by a 247cc four-stroke parallel-twin liquid-cooled engine, fed by two Mikuni carburetors, delivering 36 hp with maximum strength at 8,500 rpm and 30 Nm (22 lb-ft) torque at 8,000 rpm.

　　The engine's power was transferred to a five-speed manual transmission with a wet multi-plate clutch and sent to the rear wheel through a final chain drive.
