Yamaha YZF-R 125 (2021-2022) Review: A Pocket Rocket with Grand Ambitions

Introduction

The Yamaha YZF-R 125 has long been the gateway drug for aspiring sportbike enthusiasts, and the 2021-2022 iteration continues this legacy with a blend of razor-sharp styling and accessible performance. Designed to mimic its larger R-series siblings like the R6 and R1, this 125cc machine isn’t just a starter bike—it’s a statement. After spending a week with the Euro 5-compliant 2022 model, it’s clear Yamaha hasn’t compromised on the thrill factor, even within the constraints of A1 licensing regulations. Whether you’re a novice rider or a seasoned motorcyclist looking for a nimble commuter, the R125 demands attention.

Design & Ergonomics: Born from the R-DNA

Aggressive Aesthetics

Yamaha’s “Faster Sons” design philosophy shines here. The R125’s angular fairings, dual LED headlights, and M-shaped air intakes are ripped straight from the YZF-R1 playbook. The 2021-2022 models introduced bold colorways like Tech Black and Icon Blue, but the showstopper is the World GP 60th Anniversary Edition (2022). Drenched in Yamaha’s iconic white-and-red livery, gold forks, and blacked-out accents, this variant looks like it rolled straight out of a MotoGP paddock.

Rider-Focused Ergonomics

At 825 mm (32.5 inches), the seat height is approachable for shorter riders, though the narrow profile helps taller riders plant their feet comfortably. The clip-on handlebars are set low, encouraging a sporty forward lean, but the riding position is less extreme than full-sized supersports. Your knees grip the sculpted tank, while the rear-set pegs strike a balance between agility and comfort—perfect for carving city traffic or weekend twisties.

Performance: Small Displacement, Big Personality

Engine & Transmission

The 124.7cc liquid-cooled SOHC engine is a marvel of efficiency. With 15 HP (11 kW) at 9,000 RPM and 11.5 Nm (8.5 lb-ft) of torque at 8,000 RPM, it thrives in the upper rev range. Below 6,000 RPM, the engine feels docile, but crack the throttle open, and the Variable Valve Actuation (VVA) system kicks in, delivering a satisfying surge of power. Paired with a slick 6-speed gearbox and an assist-and-slipper clutch, shifts are precise, and aggressive downshifts won’t unsettle the rear wheel.

Fuel Efficiency & Emissions

Compliance with Euro 5 standards hasn’t dulled the fun. The R125 sips fuel at 2.13 L/100 km (110 mpg), making it a frugal companion for daily rides. CO2 emissions are a mere 49.4 g/km—a nod to eco-conscious riders.

Chassis & Handling

The steel Deltabox frame and lightweight aluminum swingarm provide a rigid yet forgiving base. Suspension duties are handled by a 41 mm USD fork (130 mm travel) up front and a linked monoshock (114 mm travel) at the rear. The setup is firm enough for spirited riding but absorbs potholes with surprising grace.

Braking & Tires

A 292 mm front disc (single piston) and 230 mm rear disc offer ample stopping power for the bike’s 144 kg (317.5 lbs) wet weight. ABS isn’t standard, but the brakes are progressive and easy to modulate. The 100/80-17 front and 140/70-17 rear tires (Michelin Pilot Street on tested models) inspire confidence mid-corner, though upgrading to stickier rubber could unlock even more grip.

Competition: How Does the R125 Stack Up?

KTM RC 125

The RC 125 trades Yamaha’s refinement for raw aggression. Its 125cc engine produces similar power, but the trellis frame and WP suspension cater to hardcore riders. However, the KTM’s seat is punishing on long rides, and its fuel efficiency trails the Yamaha.

Honda CBR125R

Honda’s offering is lighter (137 kg / 302 lbs) and slightly cheaper, but it lacks the R125’s premium touches. The CBR’s conventional forks and softer suspension prioritize comfort over sportiness, making it better suited for urban commuting.

Aprilia RS4 125

With a 15° valve engine and race-derived chassis, the RS4 125 is the R125’s closest rival. It’s quicker off the line, but Aprilia’s dealer network is sparse compared to Yamaha’s, and maintenance costs run higher.

Verdict: The Yamaha strikes the best balance between sporty dynamics, everyday usability, and brand reliability.
