Yamaha RX-Z
Encyclopedia
Yamaha RX-Z 135 is a 2-stroke naked bike manufactured by Yamaha Motor Corporation. Debuted in 1987, the RX-Z is very popular in Malaysia and Singapore and has been sold for more than two decades before the production was ended in 2011. In 2004, the model was revised cosmetically and a catalytic converter
was installed.
. The model shared the same platform and chassis as its predecessor, the water-cooled Yamaha RD125. Shortly after the launch, the RX-Z became popular among young motorcyclists especially in Malaysia. A few years later, the engine was upgraded with the installation of a 6-speed transmission, together with newer instrument panel and handlebar switches, as well as a cross-drilled front disc brake rotor.
Since then, the design of the RX-Z remained unchanged until 2004 when the model was updated, with the rear lights borrowed from the Yamaha Y125Z
. The new RX-Z was equipped with a catalytic converter
, sacrificing 1 PS of maximum power (original maximum power: 21 PS). However, the maximum torque remained unchanged but the low-end torque was improved compared with the early models. Some owners of the earlier RX-Z motorcycles may have problems during take-off because the engine tends to stall when an inexperienced rider tries to take off in the first gear. However, the problem was resolved in the new model.
The production of the RX-Z ended in 2011 after being sold for more than two decades.
In Malaysia, the RX-Z is one of the motorcycle models often associated with Mat Rempit
street racers
. As a result, many Malay movies including Remp-It
use the RX-Z in their movies.
