Overview
Who said an entry-level roadster had to settle for a straight-A student's looks? Yamaha clearly decided to toughen up the face of its Yamaha MT-03 320, and the result is a small machine that plays tough in the big leagues. The front end has hardened, sharpened, with a piercing gaze reminiscent of the MT-09 and MT-10's styling cues. You can feel the intent to fully integrate this roadster into the "Dark Side of Japan" clan. The air scoop design, borrowed from its elder siblings, visually widens the silhouette. The LED turn signals gain in sleekness. The LCD dashboard, inspired by the one that equipped the MT-10, brings a welcome touch of seriousness, even in a simplified version. Cosmetically, the transformation is a success. There's still that somewhat unsightly low headlight and the horn that's always poorly hidden — two annoying details Yamaha drags around like a pebble in its boot.

On the chassis side, the real improvement lies up front. The conventional fork gives way to a 37 mm inverted fork, a choice that changes the game in terms of rigidity and steering precision. The diamond-type steel frame remains identical, but the rear shock benefits from revised settings to offer a bit more composure. With 130 mm of travel at the front and 125 mm at the rear, we're in versatile territory, capable of soaking up urban imperfections while holding its own on twisty roads. Braking keeps it simple with a 298 mm front disc clamped by a two-piston caliper, and a 220 mm unit at the rear. Not enough to rival the bite of a KTM 390 Duke, but ABS stands guard and the contained weight of 168 kg wet keeps the package coherent. The seat at 780 mm places this Yamaha among the most accessible in the segment.
The 321 cc inline twin develops 42 horsepower at 10,750 rpm and 29.4 Nm of torque at 9,000 rpm. Honest figures, Euro5 compliant, that place the Yamaha MT-03 320 right in the middle against the 390 Duke and its 44 horsepower, or the BMW G 310 R and its 34 horsepower. The KTM takes the edge on torque, the BMW proves less spirited. What is the top speed of the Yamaha MT-03 320? Expect around 160 km/h flat out, enough to hold its own on highways without pushing the engine's temperament. The six-speed gearbox proves smooth and well-spaced, the chain drive does its job without fuss. The 14-liter tank allows for reasonable stints between fuel stops. This little twin doesn't try to impress with raw power — it banks on consistency and a progressive rev climb that builds confidence for A2 license holders.

What is the price of the Yamaha MT-03 320 2024 in France? Listed at 6,499 euros for this 2023 model year, the price has climbed compared to the first generations. What was the price of a Yamaha MT-03 320 from 2019 in France? Back then, the machine could be found under the 5,500 euro mark. The inflation is partly justified by gains in equipment and style, but against a 390 Duke sold in the same price range, the competition remains tight. Yamaha bets on its proverbial reliability, riding comfort, and a dense dealer network to make the difference. It's aimed at new license holders who want a roadster with character without going overboard, and at urban riders looking for a lightweight, easy-to-live-with machine capable of escaping on back roads come the weekend.
Yamaha isn't revolutionizing anything with this evolution of the MT-03, but it corrects the essentials. The styling finally matches the MT range's spirit, the inverted fork brings a genuine improvement to the ride, and the engine block remains a reliable companion for racking up miles without stress. It's not the most powerful or the most spectacular in its class, but it's probably one of the most well-balanced.
