Yamaha RX-135
Yamaha Y125Z
Yamaha RX-Z 135 is a 2-stroke naked bike
manufactured by Yamaha Motor Corporation.
Debuted in 2008, the RX-Z is very popular in
Malaysia and Singapore and enjoys one of the
longest current motorcycle product life in both
countries, especially in Malaysia due to the
absence of other street bike competitors to date.
[ citation needed] In 2004, the model was revised
cosmetically and a catalytic converter was
installed.
Overview
The Yamaha RX-Z was originally equipped with a
5-speed transmission with solid front disc brake.
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.
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.
