Overview
Who remembers the first Yamaha MT-03 320 and its slightly too tame face? In the Master of Torque family, it came across as the shy little sister, stuck between older siblings with much bolder personalities. Yamaha clearly heard the feedback and delivers a 2021 model year that's far more assertive. The lines have hardened, the gaze has sharpened, and the little naked bike now bears a credible family resemblance to the rest of the MT range. That said, the ungainly lower headlight and the horn still left out in the open are two details that somewhat spoil the picture.

The real progress shows in the chassis department. The adoption of a 37 mm inverted fork, replacing the old conventional unit, sends a clear signal: this MT-03 wants to attack corners. The diamond-type steel frame carries over, but the rear shock gains stiffness with revised settings. At 168 kg wet and a seat height of 780 mm, it remains an approachable machine, easy to pick up for an A2 license holder or an urban rider looking for a nimble toy. The braking setup, modest with a 298 mm front disc and a 220 mm rear disc, gets the job done without dazzling. ABS comes standard — that's non-negotiable these days.
Beneath the 14-liter tank beats a 321 cc inline twin, true to form. Its 42 horsepower at 10,750 rpm and 29.4 Nm of torque at 9,000 rpm are enough to handle daily commutes and have fun on back roads. Top speed caps out around 160 km/h, which places the bike in the same waters as the KTM 390 Duke and the Kawasaki Z400, two rivals slightly better endowed in displacement and torque. The Yamaha makes up for it with a smoothness and linearity that are genuinely appreciated, especially for beginners. The 11.2:1 compression ratio and six-speed gearbox deliver the power without brutality, through a conventional chain drive.

On the styling front, the proportions have changed. The side scoops openly draw inspiration from the bigger sisters in the range, the digital dashboard borrows the signature of the higher-end models in a simplified version, and the slim LED turn signals modernize the silhouette. The result makes you want to stare at it at a red light, which wasn't necessarily the case before. For those wondering about the price of a Yamaha MT-03 320, the sticker comes in at 5,499 euros — a slight increase that remains competitive against both European and Japanese rivals in the segment.
This evolution doesn't revolutionize anything, but it puts the MT-03 where it should have been from the start: an entry-level roadster with visual character and a serious chassis, capable of winning over new riders and experienced motorcyclists alike who are after a second bike for the city. Yamaha plays the style and accessibility card, and on that front, the little Japanese naked scores points.
