The Yamaha RX-Z 135 is a two-stroke naked bike manufactured by Yamaha Motor Corporation. Debuting in April 1985, the RX-Z was very popular in Malaysia, Singapore, and Thailand and was sold until production was ended in 2011.
In 2004, the RX-Z had a restyle and a catalytic converter was installed.
Overview
{{Refimprove section|date=November 2009}}
The first generation of the RX-Z (1985) was originally equipped with a five-speed transmission with solid front disc brake. The model shared the same platform and chassis as its predecessor the RX-135. The RX-Z became very popular among young motorcyclists in Singapore and Malaysia. A few years later in 1990, the engine was upgraded with a six-speed transmission, together with the introduction of the Yamaha Computerized Lubrication System or YCLS, as well as a new front cowl and new a gauge cluster.
The third generation RX-Z came out in 2004 when the model was updated, with the rear lights borrowed from the Yamaha Y125Z and is equipped a catalytic converter due to Euro 3 regulations and production was only up until 2011.
In Malaysia, the RX-Z was one of the motorcycle models often associated with Mat Rempits. {{Citation |date=April 1, 2009 |title=Squad 42 Battles 'Mat Rempit' Menace |first1=Lizawati |last1=Bahanan |first2=Erma |last2=Idayu Mohd Yusop |url=http://www.bernama.com/bernama/v5/newsfeatures.php?id=400817 |access-date=2009-11-23 |newspaper=Bernama }} As a result, many Malay movies including Remp-It use the RX-Z in their movies.
