Air Filter for Speed Twin 1200 / Thruxton 1200 - BMC

BMC High-Performance Cotton Air Filter for Triumph Speed Twin 1200 and Thruxton 1200

The BMC cotton performance air filter is specifically designed for direct installation inside the airbox of Triumph Speed Twin 1200 and Thruxton 1200, as a direct replacement for the OEM air filter. Made from high-performance materials, it improves airflow to the engine, optimizing breathing and delivering a quicker, smoother throttle response.

Compared to OEM paper or foam filters, the BMC filter provides superior filtration capacity, capturing particles down to 7 microns (ISO 5011 certified), versus approximately 10 microns for stock filters. This means cleaner air, better engine protection, and consistent performance over time.

BMC Construction Technology

BMC air filters are manufactured using the exclusive Full Moulding process, resulting in a one-piece filter with no glued corners, eliminating weak points and ensuring greater durability.
The signature BMC red rubber maintains its shape and perfect seal over time, fitting precisely to the airbox of Triumph 1200 models.

The filter media consists of multi-layer cotton gauze soaked in low-viscosity oil, sandwiched between aluminum mesh treated with epoxy resin to resist humidity, oxidation, and fuel vapors.
