Yamaha Rx 100: The story of the Yamaha RX 100 begins in 1985 when Yamaha Motor Corporation, in collaboration with Escorts Group, introduced this compact motorcycle to the Indian market.
The timing was perfect—India was experiencing economic liberalization, and the growing middle class was eager for affordable yet exciting personal transportation options.
The motorcycle landscape was dominated by fuel-efficient but uninspiring commuter bikes, creating a perfect opportunity for something with more character.
The RX 100 was developed with the Indian market specifically in mind. While based on Yamaha’s international small-displacement motorcycle platforms, it was adapted to suit local conditions and preferences.
The engineering team focused on creating a lightweight frame paired with a responsive engine that could handle the diverse and often challenging road conditions found across India.
What emerged was a motorcycle that weighed just 103 kg (227 lbs) powered by a 98cc two-stroke, air-cooled, single-cylinder engine that produced 11 horsepower at 7,500 rpm.
These specifications might seem modest by today’s standards, but in the mid-1980s, they represented an exceptional power-to-weight ratio that translated to thrilling performance.

The engine’s character was defined by its distinctive power band. Mild and manageable at lower revs, it transformed around 5,000 rpm, delivering a surge of acceleration that earned the motorcycle its reputation as a “pocket rocket.
” This characteristic two-stroke power delivery became one of the RX 100’s most cherished attributes, providing an exhilarating riding experience that larger, more expensive motorcycles struggled to match.
The five-speed transmission was perfectly matched to the engine’s output, with gear ratios carefully selected to keep the engine in its sweet spot.
The clutch action was light but positive, allowing for quick shifts that further enhanced the motorcycle’s responsive feel.
Beyond the powertrain, the RX 100’s chassis was equally impressive. The simple yet effective double-cradle frame provided excellent rigidity while maintaining the motorcycle’s lightweight character.
The conventional telescopic front fork and dual rear shock absorbers were tuned for a balance of comfort and handling, resulting in a motorcycle that felt nimble in city traffic yet stable at highway speeds.
The 18-inch wire-spoke wheels contributed to the RX 100’s classic appearance while providing good stability and the ability to absorb road imperfections.
The drum brakes—130mm at the front and 110mm at the rear—were adequate for the motorcycle’s performance and weight, offering predictable stopping power when needed.
Design: Timeless Simplicity
The RX 100’s design philosophy embraced minimalism long before it became fashionable. The sleek, purposeful lines created a profile that was both elegant and functional.
The long, flat seat, slender fuel tank with distinctive Yamaha graphics, and perfectly proportioned side panels created a cohesive visual identity that has aged remarkably well.
The chrome-finished exhaust with its upswept design not only looked appealing but also contributed to the motorcycle’s performance by optimizing exhaust flow.
The simple, round headlight and tail light, along with the analog instrumentation, reflected the straightforward nature of the motorcycle’s design.
What made the RX 100’s appearance so enduring was its honesty—every element served a purpose, with no superfluous styling details.
This function-led design approach resulted in a motorcycle that looked right from every angle, with proportions that emphasized its lightweight, agile character.
The color options were limited but impactful. The most iconic was undoubtedly the black and red combination, though the motorcycle was also available in black with gold graphics and, later, in silver.
These color schemes enhanced the RX 100’s visual appeal while reinforcing its sporty nature.
