2025 Yamaha RX 125: The motorcycle landscape in India has always been driven by a curious blend of nostalgia and innovation.
In this context, Yamaha’s announcement of the 2025 RX 125 has created waves across the two-wheeler community that few recent launches have managed to generate.
After months of speculation, spy shots, and teaser campaigns that had enthusiasts dissecting every pixel for clues, I finally got my hands on the production version for an extended ride through both urban congestion and open highways.
What follows is my unfiltered experience with a motorcycle that attempts the precarious balance between honoring a legendary nameplate and delivering a product relevant to today’s riders.
2025 Yamaha RX 125: The Legacy That Shadows Every New Beginning
Before diving into the 2025 model, it’s worth acknowledging the enormous shadow cast by the original RX series.
For many Indian motorcyclists who came of age in the 1980s and 1990s, the Yamaha RX 100 and its subsequent variants represented more than mere transportation—they embodied freedom, rebellion, and mechanical simplicity in an era before electronics dominated every aspect of our lives.
I still remember my neighbor’s 1990 RX 135, its distinctive exhaust note announcing his arrival long before he turned onto our street.
The lightweight frame, the immediate throttle response characteristic of two-stroke engines, and the minimalist design created a riding experience that prioritized connection and sensation over comfort or convenience.
It’s against this formidable legacy that the new RX 125 must prove itself—not as a direct replacement (which would be technically impossible given emission regulations), but as a spiritual successor that captures something of that original essence while acknowledging the realities of 2025.
Design: Respectful Evolution Rather Than Retro Pastiche
Approaching the 2025 RX 125 for the first time, I was struck by Yamaha’s restraint. Rather than creating a slavish retro replica dripping with nostalgic design cues, they’ve opted for a more subtle approach that hints at the heritage without becoming a caricature.
The fuel tank bears the closest resemblance to the original, maintaining similar proportions and knee recesses, though now crafted from metal rather than plastic—a detail that old-school enthusiasts will appreciate.
The side panels feature a modernized version of the iconic RX graphics, updated with sharper lines while preserving the essential character of the original design language.
The round LED headlamp strikes an effective compromise between retro aesthetics and modern illumination technology, providing excellent visibility during night rides through poorly lit country roads.
Similarly, the digital-analog instrument cluster offers contemporary functionality (including smartphone connectivity) within a circular housing that echoes the simplicity of the original’s speedometer.
Perhaps most successfully, Yamaha has maintained a visual lightness that was central to the RX identity.
Despite housing modern components and safety features that inevitably add weight, the design team has managed to create a motorcycle that looks nimble and unintimidating—a visual promise that, as we’ll explore, the riding experience largely delivers on.
Engine: Finding Character in a Four-Stroke World
The heart of any motorcycle is its engine, and here Yamaha faced their greatest challenge. The original RX series was defined by its two-stroke motor—a format now impossible to resurrect given current emission standards.
Instead, the 2025 RX 125 employs a thoroughly modern 125cc four-stroke single with fuel injection, liquid cooling, and variable valve actuation.
On paper, the output figures seem modest: 15 bhp at 10,000 rpm and 11.5 Nm of torque at 8,000 rpm.
These numbers, while competitive in the 125cc segment, pale in comparison to the 16.5 bhp that the smaller-displacement RX 100 produced back in 1985. However, raw numbers tell only part of the story.
During my first acceleration run on an empty stretch of highway, what impressed me wasn’t outright power but the engine’s willingness to rev.
The throttle response is immediate—not quite two-stroke immediate, but noticeably more eager than most modern 125cc motors.
The power delivery remains linear until about 7,000 rpm, at which point there’s a perceptible surge that carries through to the 11,000 rpm redline, encouraging you to wring out each gear.
The exhaust note deserves special mention. Yamaha’s engineers have clearly spent considerable effort tuning the acoustics to deliver a distinctive sound that, while obviously from a four-stroke, has a higher-pitched, more urgent character than is typical for the class. It’s a thoughtful touch that contributes significantly to the bike’s emotional appeal.
My week-long test returned fuel economy figures averaging 55-60 km/l in mixed riding conditions—roughly twice what the original RX would deliver even when ridden conservatively.
This efficiency, combined with the 10-liter tank, translates to a practical range of over 500 kilometers between fill-ups.
Chassis and Handling: The Spiritual Connection
If the engine represents a necessary departure from the original formula, the chassis and resulting handling characteristics provide the strongest connection to the RX heritage.
Weighing in at 116 kg wet, the 2025 RX 125 is certainly heavier than its predecessors (the original RX 100 weighed just 103 kg) but remains one of the lightest motorcycles in the current market.
This lightness, combined with the compact dimensions and a responsive chassis, delivers an agility that immediately feels familiar to anyone who’s ridden an original RX.
Threading through dense urban traffic becomes an exercise in precision rather than effort, with the narrow handlebar providing excellent leverage for quick direction changes.
The suspension setup—telescopic forks up front and twin shock absorbers at the rear—is tuned to prioritize responsiveness over plushness.
On smooth tarmac, this translates to a communicative ride that encourages spirited cornering. The trade-off becomes apparent on rougher surfaces, where the firm damping transmits more road imperfections to the rider than some competitors might.
During an impromptu detour down a winding mountain road, the RX 125 displayed impressive composure.
The chassis remains stable even when pushed hard, and the factory-fitted MRF tires provide adequate grip in dry conditions, though they begin to show their limitations in the wet.
Braking duties are handled by a 240mm front disc with a twin-piston caliper and a 130mm rear drum, supplemented by single-channel ABS.
The setup provides reliable stopping power for everyday riding, though enthusiastic riders might wish for a bit more initial bite from the front brake during spirited sessions.
Electronics: Minimal Yet Modern
Yamaha has exercised admirable restraint with the electronics package, offering modern essentials without overwhelming the riding experience with unnecessary features. Beyond the mandated ABS, the RX 125 includes:
Two riding modes (Normal and Sport) that subtly alter throttle response
Bluetooth connectivity for call notifications and turn-by-turn navigation
USB-C charging port discreetly mounted near the instrument cluster
LED lighting throughout
Notably absent are the multiple traction control settings, riding modes, and customizable dashboards that have become common even in the 125-150cc segment.
This minimalist approach feels appropriate for a motorcycle that draws inspiration from a simpler era of motorcycling.
The Bluetooth-enabled Y-Connect app provides access to ride statistics, maintenance reminders, and last-parked location—useful features that enhance ownership without intruding on the riding experience.
Ergonomics: Balancing Heritage and Comfort
The riding position strikes a balance between the committed stance of the original RX and the more upright ergonomics preferred by today’s riders.
The seat height of 795mm makes the motorcycle accessible to riders of varying statures, while the relatively rear-set footpegs encourage a more engaged riding posture than is typical for the commuter segment.
During my 200-kilometer highway test, I found the seating comfortable enough for two-hour stretches before needing a break—significantly better than the original RX but still sporting enough to feel connected to the machine. The narrow tank allows for easy gripping with the knees during cornering, enhancing the sense of control.
Passenger accommodations are basic but functional, with grab rails that provide security without disrupting the clean lines of the rear section.
The two-up ergonomics work well for short to medium journeys, though the firm rear suspension becomes noticeable on longer rides.

The Ownership Experience: Beyond the Ride
A week with any motorcycle reveals only part of the ownership story, so I spoke with several early adopters who’ve lived with the RX 125 since its soft launch three months ago. Their experiences highlighted aspects that wouldn’t be apparent during a test ride.
Maintenance costs align with other premium 125cc motorcycles, with service intervals set at every 3,000 kilometers.
The liquid-cooled engine requires more specialized attention than the air-cooled units of the original RX series, but Yamaha’s extensive service network provides reassurance.
Parts availability has been excellent even in smaller towns, addressing a common concern with newly launched models.
Several owners mentioned the growing community around the new RX, with ride groups and social media forums already establishing traditions like Sunday morning rides and modification showcases.
Customization potential appears strong, with aftermarket companies already offering everything from performance exhausts to vintage-inspired appearance kits.
Yamaha themselves offer three accessory packages: Heritage (emphasizing retro styling elements), Performance (focused on riding dynamics), and Touring (adding practicality for longer journeys).
The Inevitable Question: Is It a True RX?
Throughout my time with the 2025 RX 125, one question persistently surfaced in conversations with fellow enthusiasts: “Is it a true RX?” The answer, I’ve concluded, depends entirely on how one defines that legacy.
If “true RX” means a lightweight, simple two-stroke with raw power delivery and a distinctive ring-ding exhaust note, then no—environmental regulations and modern safety standards make such a recreation impossible. The physics and chemistry that made those machines special cannot be replicated within current constraints.
However, if the essence of the RX identity lies in its approach to motorcycling—prioritizing lightness, agility, and rider connection over overwhelming power or luxury—then this new interpretation succeeds admirably.
It captures something of that original spirit while acknowledging that 2025 is not 1985.
The 2025 RX 125 isn’t a resurrection but a reinterpretation, offering a bridge between generations of riders. For those who grew up idolizing the original, it provides a modern machine that evokes familiar sensations without the maintenance headaches.
For younger riders discovering the RX legend for the first time, it offers an entry point to that heritage wrapped in contemporary reliability.
In creating this motorcycle, Yamaha faced an impossible task—satisfying purists while attracting new enthusiasts.
That they’ve produced something that feels honest rather than exploitative speaks to the respect with which they’ve approached this revival.
The 2025 Yamaha RX 125 may not be the RX of yesterday, but it is perhaps the RX that today’s world allows—a thoughtful homage that carries forward not the specifics but the spirit of a motorcycling icon. And in that careful balance between nostalgia and progress, it finds a compelling identity all its own.
