Yamaha R125 2022 — Specifications

Who would have thought that a small 125 cc single-cylinder could one day mimic superbikes with such confidence? The 2022 Yamaha R125 doesn't settle for playing the well-behaved mini-sportbike card. It claims a heritage—that of the R1 and R6—and it does so with a conviction that commands respect. At €5,799, this Yamaha R125 is aimed at young A1 license holders who want to thrill on a steel Deltabox frame without waiting for a big-bore machine. It's a bold bet. The result is rather convincing.

On the styling front, Yamaha went all in. The silhouette has hardened, the lines have sharpened, and the fairing clearly borrows from previous generations of the R6 while eyeing the current R1. You'll find sculpted air intakes on the tank, a redesigned tapered tail, and full LED headlights that give this 125 the look of a purebred sportbike. In black, the Yamaha R125 takes on a particularly aggressive stance. It's hard to guess the displacement at first glance. That's precisely the intended effect. Up against a KTM RC 125 or an Aprilia RS 125, the Japanese contender holds its own. Visually, it even plays in the big leagues, which remains its main selling point.

Beneath the fairing, the 124.7 cc four-stroke single-cylinder produces 15 horsepower at 10,000 rpm and 11.5 Nm of torque at 8,000 rpm. It stays within regulatory limits—no miracles here. But Yamaha has refined this engine with a VVA variable valve actuation system, a first in the category. The wider throttle body, the redesigned cylinder head with four shorter and wider valves, the 11.2:1 compression ratio: everything has been calibrated to deliver responsiveness at low revs and breath at the top end. The Yamaha R125 tops out at 125 km/h, placing it squarely in the segment average. The six-speed gearbox and assist-and-slipper clutch add a touch of mechanical sophistication not always found among its rivals. The claimed fuel consumption of 2.1 liters per 100 km, combined with the 11.5-liter tank, allows for a comfortable theoretical range for a pocket-sized sportbike.

The Deltabox chassis has been revised in its geometry for sharper handling. The 41 mm inverted fork works with a cast aluminum swingarm that is shorter and stiffer than its predecessor. The rear tire moves up to a 140/70-17, a choice that improves cornering grip. Braking relies on a single disc at each wheel, with a redesigned rear caliper. The 144 kg wet weight remains reasonable, even if the 825 mm seat height may intimidate smaller riders. The ergonomics have been reworked: clip-on handlebars with a wider spread, a thicker seat, and a redesigned tank for better knee grip during spirited riding. The LCD dashboard displays the selected gear, VVA status, and a tachometer bar graph. This is no gimmick—it's a genuine cockpit.

The 2022 Yamaha R125 spec sheet confirms one thing: Yamaha takes the 125 sportbike segment seriously. For a young rider seeking a first bike with real thrills, it's a solid choice. Those eyeing a used Yamaha R125, whether a 2018, 2019, or 2021 model, will find machines that were already well conceived, but this generation marks a true milestone. The competition, from the Honda CBR125R to the Aprilia RS 125, offers credible alternatives, but none pushes the sportbike identity this far into the details. The R125 doesn't pretend to be a full-size machine. It behaves as though it were one, and that's what makes it so endearing.
