Engine & Performance

The 125 cc single is tuned for crisp response and real-world usability. With 11.0 kW (15.0 PS) at 10,000 rpm and 11.5 Nm at 8,000 rpm, the R125 rewards riders who enjoy working a gearbox and carrying momentum. Its 52.0 mm x 58.7 mm bore and stroke and 11.2:1 compression ratio speak to an engine that blends rev-happy character with approachable torque for city getaways and twisty backroad fun.

A constant mesh 6‑speed transmission keeps the motor in the sweet spot, while electronics elevate control: traction control enhances confidence on sketchy surfaces, and the Assist & Slipper clutch smooths downshifts and lightens the lever feel. It’s quickshifter‑ready too, so you can add that feature if you want even more seamless upshifts. Fuel injection, TCI (digital) ignition, and wet‑sump lubrication underscore Yamaha’s emphasis on reliability and clean running, capped by EURO5+ compliance and a low 47 g/km CO2 figure. With a WMTC rating of 2.1 L/100 km and an 11.0 L tank, efficiency is a clear strong point.

Handling, Comfort & Yamaha R125 Seat Height

The chassis aims for confidence and precision. Geometry numbers—26° caster angle, 95 mm trail, and a compact 1325 mm wheelbase—suggest nimble steering with reassuring stability mid-corner and on the brakes. A 41 mm upside-down fork with 130 mm of travel provides a planted front end, while a link‑type swingarm and 110 mm of rear travel help the rear tire track cleanly over bumps. Tire sizes (100/80‑17 front, 140/70‑17 rear) strike a solid balance between agility and grip.

Yamaha R125 seat height is 820 mm (official), giving a sporty stance without feeling extreme. Shorter riders may appreciate the narrow 125 package when easing a foot down at lights, while taller riders should still find adequate legroom for daily rides. The Yamaha R125 weight is 141 kg (wet, official), which helps low‑speed maneuvering and parking without dulling stability at higher pace. Minimum ground clearance of 160 mm also makes speed bumps and steep driveways less stressful for an everyday sport bike.

Who Is the 2026 Yamaha R125 For?

The R125 is ideal for riders stepping into the sport segment who want genuine supersport feel scaled to a 125. It’s equally at home as a daily commuter—thanks to its slim size, smooth fueling, and excellent economy—or as a weekend canyon companion where you can enjoy its chassis finesse. Experienced riders looking for a lightweight training tool or urban runabout will appreciate the control electronics, TFT instrumentation, and the way the suspension and geometry reward clean technique.

Torquepedia Verdict

The 2026 Yamaha R125 combines an efficient, characterful single with a well-sorted chassis and a features list that feels thoroughly modern. Traction control, an Assist & Slipper clutch, quickshifter readiness, and a 5‑inch TFT would be noteworthy on bigger bikes—seeing them here is a win for 125 riders. Add EURO5+ cleanliness, low CO2, and standout economy, and you’ve got a sport 125 that’s as smart as it is stylish.

On the flip side, the seat height of 820 mm may be a touch tall for the shortest riders, and power is capped to typical 125‑class levels. But judged on completeness and rider friendliness, the R125 is a compelling pick for learners, commuters, and enthusiasts who value precision more than outright muscle.
