BMC 2018 + KTM 790 Duke Replacement Air Filter

BMC Air Filter KTM 790 Duke (2018+) | High-Flow Performance Filter

Upgrade your 2018+ KTM 790 Duke with a BMC High-Flow Replacement Air Filter. Boost throttle response, increase airflow, and protect your engine with this washable, reusable cotton gauze filter.

Engineered in Italy for riders who demand maximum performance from their middleweight naked bike, the BMC Replacement Air Filter (Part # FM01026) is the ultimate drop-in upgrade for the 2018+ KTM 790 Duke. Designed to replace the restrictive factory paper element inside the original airbox, this high-flow filter allows up to 35% more airflow into the LC8c parallel-twin engine, significantly sharpening throttle response and improving power delivery throughout the rev range.

The filter is constructed using BMC's signature multi-layered cotton gauze saturated with low-viscosity oil and encased within an epoxy-coated alloy mesh. This mesh shields the filtration material against fuel fumes and humidity oxidation. Built using BMC’s proprietary "Full Moulding" technology, the seamless red polyurethane frame eliminates weak welded joints to guarantee structural integrity and a perfect, airtight seal inside the airbox. Unlike disposable stock filters, the BMC air filter is completely washable and reusable, offering lifelong engine protection and sustained performance.

Best Uses

1. Daily Street Riding & Commuting: Enhances engine efficiency, smoothness, and throttle response during urban and highway riding.
2. Aggressive Canyon Carving & Track Days: Maximize intake airflow to complement aftermarket exhaust systems and ECU tunes during high-RPM riding.
3. Long-Term OEM Maintenance: Replaces restrictive disposable paper filters with a washable, lifetime solution.

Features

1. Multi-Layer Oiled Cotton Gauze: Captures micro-impurities as small as 7 microns while allowing significantly higher air volume than OEM paper filters.
2. "Full Moulding" Polyurethane Frame: Manufactured from a single continuous mold with no welded joints, preventing structural failure or cracking over time.
3. Epoxy-Coated Alloy Mesh: Protects the cotton media from environmental oxidation and gasoline fumes.
4. Direct OEM Fitment (Drop-In Upgrade): Specifically engineered to fit the 2018+ KTM 790 Duke airbox without requiring modifications.
5. Washable & Regenerable Media: Designed to be cleaned and re-oiled using BMC’s wash kit for indefinite reuse.

Benefits

1. Increased Airflow & Power: Provides up to 35% more airflow over standard paper filters, unlocking better power and torque delivery.
2. Sharper Throttle Response: Minimizes air intake resistance for instantaneous engine response when twisting the throttle.
3. Superior Filtration Efficiency: Traps finer particles than typical stock filters to protect internal engine components from wear.
4. Cost-Effective Lifetime Solution: Eliminates the ongoing cost of replacing standard disposable filters during routine servicing.
5. Eco-Friendly Construction: Reduces landfill waste associated with single-use paper filter replacements.
