BMC Air Filter for Triumph Speed 400 / Scrambler 400X

A BMC filter is a washable cotton element that replaces the paper filter your bike came with. Paper filters are consumables - they clog, they restrict airflow as they do, and you buy another one. A BMC is cleaned and re-oiled instead, and BMC rate them for the life of the engine.

The airflow gain is real but modest on a stock bike: expect slightly crisper throttle response rather than a power figure you can feel. The honest case for one is running cost and, in Indian conditions, the fact that a washable element copes better with dust than a paper filter you are reluctant to replace every few thousand kilometres.

This is the direct-fit element for the Triumph Speed 400 and Scrambler 400X - it drops into the standard airbox with no modification. Part number FM01209.

FAQs

Q: Will I gain power?
On a stock bike, very little - expect slightly better throttle response, not a meaningful power figure. The real gain is that it does not degrade like paper as it fills.

Q: How often do I clean it?
Roughly every 10,000 km in normal use, sooner if you ride a lot of dust. Wash with BMC cleaner, dry fully, re-oil lightly. Over-oiling is the common mistake and it can foul a sensor.

Q: Do I need a remap?
No. It is a direct replacement element in the standard airbox.

Q: Does it affect my warranty?
A drop-in filter is not normally an issue, but the decision rests with your service centre. Ask them if the bike is still under warranty.

Q: Will it fit my bike?
This part (FM01209) fits the Triumph Speed 400 and Scrambler 400X. Send us your model year and we will confirm before shipping.

On Indian roads an air filter works harder than the service interval assumes. A washable element you actually clean beats a paper one you keep meaning to replace. Browse more maintenance parts.
