BMC Air Filter FM01209 for Triumph Speed 400 (2024>) / Scrambler 400 X (2024>) / Scrambler 400 XC (2025>) – High-Flow Washable Performance Air Filter (Replaces TA581001)

If you want a clean, proven performance upgrade for Triumph’s new 400 platform, the BMC FM01209 is the right air filter to start with. It is a high-flow, washable oiled cotton gauze filter engineered as a direct replacement for the stock air filter used on Triumph Speed 400 (2024>), Scrambler 400 X (2024>), and Scrambler 400 XC (2025>). 

Unlike disposable paper filters, BMC filters are designed to be cleaned and re-oiled and reused, giving you lower long-term running cost and consistent airflow across service intervals. BMC lists OEM cross reference: TRIUMPH TA581001, and box content is 1 air filter (single unit). 

What this is: a genuine BMC aftermarket performance air filter (not a Triumph “OEM” branded filter). 
What this is not: it is not compatible with Royal Enfield models and not meant for other Triumph platforms (Street Triple/Tiger/Bonneville, etc.).
