Vehicle Information
Yamaha MT-03 Motorcycle - Street (2018-2026)
The Yamaha MT-03, a popular "Hyper Naked" motorcycle, has maintained a consistent engine platform from 2018 to 2026, with several key updates and refinements over the years. Throughout this period, the MT-03 has primarily been offered as a single model, with variations mainly in color schemes rather than distinct trim levels. Powered by a 321cc liquid-cooled, DOHC parallel-twin engine, it consistently delivers around 41 to 42 horsepower. While the MT-03 did not feature traditional trim levels, it received significant updates. The 2020 model introduced aggressive styling with LED lighting, a 37mm inverted KYB front fork, and a new LCD instrument cluster. In 2022, the engine was updated for Euro 5 compliance. The 2025 and 2026 models added an Assist & Slipper clutch, smartphone connectivity, an enhanced LCD display, and a redesigned tail section with a slimmer seat. The core 321cc parallel-twin engine remained largely consistent, focusing on smooth and usable power delivery. Q: Did the Yamaha MT-03 have major changes between 2018 and 2026?
A: Yes, significant updates were introduced in 2020 and 2025. To find parts compatible with your specific model, please use the year and edition selector on this page.
