The Yamaha RX-K 135 was also known as RX-King in Indonesia. It was sold as the RX-K in Malaysia and Singapore and as the RX-T 135 in the Philippines. The RX-K is a two-stroke engine motorcycle manufactured by Yamaha Motor Co., Ltd. in and for Southeast Asia.
Before the RX-K, there was the RX 125 (1976) and the RX 100.[1] The RX line was originally developed for the Indian market, where it was manufactured by Rajdoot – the RX name signifies "Rajdoot × Yamaha".[2] The original RX-K 135 was released in 1980 as the top model, fitted with a bikini fairing and imported to Indonesia fully built-up. This model has a max power of at 8,750 rpm and of torque at 8,000 rpm; it weighed in at . There was also the similar RX-S (later RX-Special), fitted with a 115 cc engine and also imported CBU.[3] In 1983, the RX-K was updated to become the locally built RX-King.
In Indonesia the RX-King 135, was produced by beginning in 1983. The first RX-King had a new reshaped petrol tank and updated seat; because of the raised handle bars this was nicknamed "Cobra" in Indonesia.[4] The first generation is sought after as they were fitted with an imported, Japanese-made engine (engine codes Y1 and Y2) producing and of torque at 8,000 rpm.[1] The engine benefitted from Yamaha Energy Induction System, developed after extensive customer surveys to meet Indonesian buyers' demand for low-down power and good fuel economy.[4]
A locally manufactured engine replaced the imported version after 1991, with the new model being nicknamed the RX-King "Master".[5] Maximum power crept up to at 9,000 rpm.[5] The Master received another light facelift in 1997. In 2002 the "New RX-King" arrived with the square headlight replaced by a round unit.[4] The rear light was also changed, and the instrumentation was redesigned. Stricter emissions requirements kicked in, and from 2006 the RX-King in Indonesia used a catalytic converter, which allowed it to pass Euro 2 regulations.[5] The appearance was also changed for a final time,
The RX-King had a significant impact on Indonesia's motorcycle market.[1] Now many people are buying the sought-after motorcycle, in particular the RX-King Cobra because it had genuine Yamaha parts from Japan and had a reputation for being very fast despite only having a 135 cc engine. The motorcycle also had a more negative association with snatchers (jambret) and pickpockets as they showed a preference for using the RX-King as a getaway motorcycle.[2] [3] Hit songs have also been written about it, such as RX-King Senggol Dong Boss By and Numpak RX-King by .[6] There spanned four generations of the motorcycle, sold in Indonesia from 1980 to 2009.
