Engine & Performance

At the heart of the MT-03 is a 321 cc, 2-cylinder engine with a 68.0 mm / 2.68 in × 44.1 mm / 1.74 in bore and stroke and a 11.2:1 compression ratio. It makes a peak 30.9 kW (42.0 PS) at 10,750 rpm and 29.6 Nm / 21.8 lb-ft at 9,000 rpm—figures that translate to a lively, rev-happy character ideal for city merges and spirited B-road runs. Despite the high-rev ceiling, the twin remains smooth and usable across town, benefiting from Electronic Fuel Injection and a TCI ignition system for crisp response.

A Constant Mesh, 6-speed transmission and chain final drive keep the MT-03 engaging without complicating the ride. The wet, multiple-disc clutch and wet sump lubrication are durability-minded touches riders appreciate during daily use. Fuel consumption is listed at 4.1 L / 100 km, and with a 14 L / 3.70 gal tank, the bike is set up well for commuting and weekend coffee runs. CO2 emissions are rated at 94 g/km.

Handling, Comfort & Yamaha MT-03 Seat Height

The MT-03’s Diamond frame, compact wheel base of 1,380 mm / 54.33 in, and geometry of 25º caster with 95 mm / 3.74 in trail add up to quick steering with stable feedback. Up front, telescopic forks with an Ø37.0 mm / 1.46 in inner tube deliver 130 mm / 5.12 in of travel, paired with a swingarm rear offering 125 mm / 4.92 in. Tyre sizes—110/70-17M/C (54H) tubeless at the front and 140/70-17M/C (66H) tubeless at the rear—strike a balance between light steering and planted grip.

The Yamaha MT-03 seat height comes in at 780 mm / 30.71 in, making flat-footing attainable for many riders and corner entry confidence high. The Yamaha MT-03 weight is 168 kg / 370.4 lb (wet), which contributes to friendly low-speed maneuvering, parking-lot ease, and quick transitions. With a minimum ground clearance of 160 mm / 6.30 in and a narrow overall width of 755 mm / 29.72 in, the MT-03 is well-suited to threading through traffic and hopping between urban neighborhoods.

Equipment & Features

Braking is handled by a hydraulic single disc up front—Ø298 mm / 11.73 in—and a hydraulic single disc at the rear—Ø220 mm / 8.66 in—providing predictable stopping power for the bike’s size and intent. The electric starter, Electronic Fuel Injection, and TCI ignition make for reliable, easy starts in all conditions, while the wet, multiple-disc clutch keeps lever feel consistent.

A practical 14 L / 3.70 gal fuel tank complements the efficient engine, and the oil tank capacity is 2.40 L / 0.63 gal for straightforward maintenance. The overall dimensions—2,090 mm / 82.28 in length and 1,070 mm / 42.13 in height—keep it compact without feeling cramped.

Who Is the 2023 Yamaha MT-03 For?

Riders stepping up from a small-displacement single, A2-friendly riders seeking a forgiving yet exciting platform, and experienced urban commuters wanting a nimble naked will all find appeal here. The approachable Yamaha MT-03 seat height, modest Yamaha MT-03 weight, and smooth power delivery make it beginner-friendly, while the high-rev punch and composed chassis keep seasoned riders entertained on twisty roads.

Torquepedia Verdict

If your short list is centered on agility, approachability, and real-world practicality, the 2023 Yamaha MT-03 delivers. The 321 cc twin’s 30.9 kW (42.0 PS) top-end pull and 29.6 Nm / 21.8 lb-ft torque give it enough verve to be fun, while EFI, TCI ignition, and a 6-speed box keep the day-to-day experience refined.

Strengths include its low seat height, manageable wet weight, and well-judged chassis geometry. The single-disc braking setup and lightweight focus signal a bike built for streets and backroads rather than hardcore track days, but that’s exactly where the MT-03 shines. In its class, it’s a smart, confidence-inspiring pick with the right blend of performance and ease of use.
