The Yamaha RX-Z 135 was a two-stroke naked bike manufactured by Yamaha Motor Corporation. It was introduced in April 1985 and sold in Malaysia, Singapore and Thailand. Production ended in July 2011.[2]
Overview
The first generation of the RX-Z, released in 1985, was equipped with a five-speed transmission and a front disc brake. The model used the same platform and driveline as its predecessor, the RX-135. In 1990, the RX-Z engine was updated with a six-speed transmission. Yamaha also introduced the Yamaha Computerized Lubrication System (YCLS), along with a designed front cowl and gauge cluster. The third-generation RX-Z was introduced in 2004 with modified styling and the addition of a catalytic converter.[3] Yamaha discontinued the model in 2011.[2]
