Take your KTM 390 Duke to the next level with the BMC Race Series air filter. Specifically developed for riders who demand the absolute best in engine performance, this race-spec filter offers significantly higher permeability than standard replacement filters, allowing your engine to breathe freely at high RPMs.

Engineered for the Track

• Race-Grade Filtration: Designed for closed-course competition where maximum power output is the primary objective.

The BMC Race Series filter is the preferred choice for enthusiasts looking to squeeze every bit of power out of their 390 Duke. By reducing intake restriction, you allow your engine to reach its full potential, especially when paired with an aftermarket exhaust system. Please note that because this is a race-focused component, it is designed for maximum flow, which may require more frequent cleaning intervals depending on riding conditions.
