The Yamaha RX100 is a name that resonates deeply within the hearts of two-wheeler enthusiasts, particularly in India. This legendary machine, first introduced in 1985, carved a unique niche for itself with its potent performance and distinctive character. For many, the RX100 wasn't just a motorcycle; it was a symbol of raw power and exhilarating riding. Now, after years of absence, whispers and strong indications suggest that this beloved icon is poised to make a triumphant return to the Indian market, promising to reignite the passion it once commanded.

Who made the RX100?
The main competitor of the Rx100 was Hero Honda CD100 and Ind-Suzuki AX 100. Later came the Kawasaki Bajaj KB 100. The RX100 was first marketed in India by Escorts Limited in partnership with Yamaha Motor Corp Japan. The first-introduced RX 100 models were fitted with Japanese engines until Escorts started making the engines in India.

The Genesis of a Legend: Yamaha RX100's Debut

Launched in India in 1985, the Yamaha RX100 was an instant sensation. It wasn't just another commuter bike; it was a performance-oriented machine that punched well above its weight. Powered by a 98cc, 2-stroke, single-cylinder, air-cooled engine, it delivered a spirited 11 bhp of power at 7500 rpm. This, coupled with a nimble chassis featuring a double cradle frame and a four-speed gearbox, allowed the RX100 to achieve a top speed of 100 km per hour, a remarkable feat for its class at the time. Its availability in appealing colours like Cherry Red and Black further cemented its appeal.

Rivals and Reign

In its heyday, the RX100 faced stiff competition from other notable motorcycles of the era. Its primary rivals included the Hero Honda CD100 and the Ind-Suzuki AX 100. Later, the Kawasaki Bajaj KB 100 also entered the fray. However, the RX100 consistently stood out due to its superior performance and engaging ride dynamics. It was a bike that riders craved, offering an unparalleled thrill that its competitors struggled to match.

Partnership and Production

The initial marketing and distribution of the Yamaha RX100 in India were handled by Escorts Limited, in collaboration with Yamaha Motor Corp. Japan. An interesting aspect of its early production was the use of Japanese-imported engines in the first batches of RX100 models. This was a testament to Yamaha's commitment to quality. Subsequently, Escorts began manufacturing the engines domestically in India. The RX100s equipped with the original Japanese engines are particularly cherished by Indian bike enthusiasts today, often considered the most desirable variants due to their impeccable build quality and performance.

Why the RX100 Became a Cherished Possession

The enduring appeal of the Yamaha RX100 lies in several key factors. Firstly, its performance was exceptional for its 100cc displacement, offering exhilarating acceleration and a lively top-end. Secondly, its handling characteristics were praised for being sharp and responsive, making every ride an engaging experience. Perhaps most importantly, the RX100 was known for its remarkably low maintenance requirements. This combination of thrilling performance, agile handling, and ease of ownership made it a bike that owners were reluctant to part with. Many still hold onto their RX100s, preserving them as prized possessions.

The End of an Era: Discontinuation and Reasons

The reign of the two-stroke king, the Yamaha RX100, lasted for 11 years in the Indian market. Production ceased in March 1996. The primary reason for its discontinuation was the tightening emission norms. As environmental regulations became more stringent, the 2-stroke engines, known for their higher emissions, struggled to comply. This led to the retirement of the beloved RX100, leaving a void in the performance motorcycle segment.

There were also some colourful, albeit unconfirmed, rumours circulating about the RX100's demise. One persistent rumour suggested that its rapid acceleration and agility made it a favourite among criminals for quick getaways, leading to its ban. Another more colourful, and likely apocryphal, tale spoke of dedicated "Yamaha Wards" in Bangalore hospitals due to the high number of accidents involving the bike. While these stories add to the RX100's mystique, the official reason for its discontinuation remains the inability to meet evolving emission standards.

The Rumoured Comeback: A New Chapter

The good news for fans is that Yamaha is reportedly working on a successor, or at least a spiritual successor, to the RX100. India Yamaha Motor's national business head, Pankaj Dubey, has indicated that the company is exploring the possibility of launching a product with a similar appeal. However, it's confirmed that the new model will not feature a 2-stroke engine due to emission regulations. Instead, the focus is on developing a 4-stroke version that can meet the latest BS-IV emission norms in India. There's also speculation that Yamaha might draw inspiration from advanced 2-stroke technologies, such as those used in Italian bikes like the Aprilia RS 125, to potentially develop a cleaner, more modern 2-stroke engine, though a 4-stroke is the more probable route.
