Aluminum Radiator Guard For Yamaha MT-03 - 2015 to 2024

The Yamaha MT-03 is a lightweight naked twin designed for everyday riding and entry-level sport performance. Its compact radiator sits forward-facing at the front of the engine bay, fully exposed to the front wheel's debris throw across all riding conditions. Stone chips, road debris, and insect strikes hit the radiator fins directly on every ride. A bent fin row reduces coolant flow efficiency and, if a bend causes a small leak, requires immediate repair before the bike can continue in service. This aluminum radiator guard mounts directly in front of the MT-03's radiator core, providing physical protection against the most common causes of radiator damage without affecting airflow or engine temperature.

The guard is CNC-machined or precision-formed from 6061 aluminum alloy with a black anodized finish. The aluminum construction matches the MT-03's aesthetic of visible mechanical components and gives the guard a more premium appearance than a stamped steel equivalent. It mounts using the factory radiator bracket bolts, with the guard frame sandwiched between the bracket and the radiator body — no additional hardware required beyond the supplied fasteners. The mesh pattern is sized to stop fragments above 3mm while maintaining approximately 85% of unobstructed radiator airflow.

Confirmed fitment for the Yamaha MT-03 produced from 2015 through 2024, covering both the original (2015-2019) and updated (2020-2024) generations. The radiator mounting architecture remained consistent across this production span. The guard also fits the Yamaha YZF-R3 from 2015 onwards, which uses the same engine and cooling system as the MT-03.

Frequently Asked Questions

Does it also fit the MT-25?

The Yamaha MT-25 is the 250cc variant sold in select Asian markets, sharing the same chassis and cooling architecture as the MT-03. The radiator guard fits the MT-25 with the same bracket positions. If your MT-25 has a different market specification (some MT-25 variants were produced with slightly different bodywork for specific markets), verify the radiator bracket hole spacing before ordering.

Will it affect the cooling fan operation?

The MT-03 uses a thermostatically-controlled radiator cooling fan that activates in traffic and slow-speed conditions. The guard mounts on the incoming airflow side of the radiator, ahead of the fan, which operates on the engine side. Fan activation timing and operating temperature are not affected by the guard installation.
