The Yamaha RX100 stands as an icon in the history of Indian two-wheelers, a motorcycle that not only defined an era but also set benchmarks for performance and reliability. Launched in India in November 1985, the RX100 was Yamaha’s answer to the growing demand for lightweight, agile, and efficient commuter motorcycles. The bike was produced until March 1996, during which it cemented its place in the hearts of enthusiasts and everyday riders alike. Its arrival marked a significant shift in the Indian motorcycle market, offering a blend of sporty performance and practical usability that was rare at the time.
Yamaha RX100 Specifications, Design, Safety, and Features
The Yamaha RX100 was designed as a commuter sports motorcycle, but its appeal quickly transcended its segment. With a compact frame, the bike measured 1965 mm in length, 740 mm in width, and 1040 mm in height. Its wheelbase of 1245 mm and ground clearance of 136 mm made it ideal for Indian road conditions, ensuring stability and maneuverability in city traffic and on rougher rural roads. The seat height stood at 765 mm, making it accessible to a wide range of riders.
In terms of safety, the RX100 maintained a straightforward approach. It featured drum brakes on both the front and rear wheels, which, while basic by today’s standards, were reliable and easy to maintain. The suspension setup consisted of telescopic forks at the front and a swing arm with adjustable shock absorbers at the rear, providing a comfortable ride even on uneven surfaces. The bike’s 18-inch wheels, fitted with tube-type tyres sized 2.50/18 at both ends, contributed to its balanced handling.
The RX100’s features were simple yet functional. The instrument console was fully analogue, with a speedometer and odometer, and the bike was equipped with a halogen headlight, bulb-type taillight, and turn indicators. The inclusion of a pass switch and passenger footrest added to its practicality, while the 10-liter fuel tank ensured a decent range between refueling stops. The focus on simplicity and reliability was a hallmark of the RX100, making it easy to maintain and repair.
Yamaha RX100 Engine and Performance
At the heart of the Yamaha RX100 was its legendary 98cc, air-cooled, single-cylinder, two-stroke engine. This powerplant was renowned for its smoothness, responsiveness, and unmistakable exhaust note. The engine featured a 7-port torque induction system, which enhanced fuel-air mixture flow and combustion efficiency. With a bore and stroke of 50 mm each and a compression ratio ranging from 6.8:1 to 7.4:1, the RX100 delivered a lively performance that belied its modest displacement.
The engine produced a maximum power output of 11 PS at 7500 rpm and a peak torque of 10.39 Nm at 6500 rpm. These figures translated into brisk acceleration and a top speed of around 100–110 km/h, making the RX100 one of the quickest bikes in its class. The 4-speed constant-mesh manual gearbox provided smooth and precise shifts, while the chain drive ensured efficient power delivery to the rear wheel. The carbureted fuel system, with a 24mm carburetor, struck a balance between performance and fuel economy.
Yamaha RX100 Technology and Features
While the Yamaha RX100 may not have boasted the advanced electronics or digital displays seen on modern motorcycles, it was a marvel of engineering simplicity. The two-stroke engine, with its piston port intake and forced air cooling, was designed for reliability and ease of maintenance. The analogue instrument cluster, though basic, provided all the essential information a rider needed. The electrical system was straightforward, with a halogen headlamp for adequate night visibility and bulb-type indicators and taillight for signaling and safety.
The RX100’s chassis was built for durability, with a commuter-friendly frame that could withstand the rigors of daily use. The adjustable rear suspension allowed riders to tailor the ride quality to their preference or load, enhancing comfort on longer journeys. The absence of complex electronics meant fewer potential points of failure, a factor that contributed to the RX100’s legendary reliability.
Yamaha RX100 Efficiency and Practicality
One of the RX100’s greatest strengths was its efficiency and practicality. The two-stroke engine, while delivering spirited performance, was also remarkably frugal. Depending on riding conditions and maintenance, the RX100 could return a fuel economy ranging from 25 to 45 kmpl, with some reports suggesting figures as high as 58.8–105.8 mpg (2.2–4 L/100 km) under optimal conditions. This made it an economical choice for daily commuting, especially in an era when fuel prices were a significant concern for most Indian families.
The 10-liter fuel tank, with a 1.5-liter reserve, provided a practical range of approximately 164–296 miles on a full tank, reducing the frequency of refueling stops. The bike’s lightweight construction, weighing in at around 103 kg, made it easy to handle in traffic and park in tight spaces. The single-piece seat offered comfort for both rider and pillion, while the passenger footrest and grab rail added to its usability.
Yamaha RX100 Price and Availability
During its production run, the Yamaha RX100 was positioned as an affordable yet premium offering in the Indian motorcycle market. Its initial price was competitive, making it accessible to a broad spectrum of buyers, from young enthusiasts to family commuters. In today’s context, the RX100’s legacy has only grown, with well-maintained examples commanding high prices in the used market due to their cult status and enduring appeal.
For those interested in acquiring a Yamaha RX100 today, the price varies significantly based on the bike’s condition, originality, and location. Restored and well-preserved models can fetch anywhere from Rs. 50,000 to over Rs. 1 lakh, reflecting the strong demand and limited supply. Rumors and discussions about a potential relaunch or modern reinterpretation of the RX100 continue to circulate, but as of now, the original remains a prized possession among collectors and enthusiasts.
Yamaha RX100 Mileage
The RX100’s two-stroke engine was known for its balance of performance and efficiency. On average, the bike delivered a mileage of 25–45 kmpl, depending on riding style, maintenance, and road conditions. Enthusiasts who maintained their bikes meticulously and rode conservatively could achieve figures at the higher end of this range, while spirited riding or city traffic could bring the numbers down. Despite being a performance-oriented machine, the RX100’s fuel efficiency was a key factor in its widespread popularity.

Yamaha RX100 Heritage and Evolution
The Yamaha RX100’s heritage is deeply rooted in its design philosophy and the cultural impact it had on Indian motorcycling. When it was launched in the mid-1980s, the Indian market was dominated by heavier, less efficient motorcycles.
