Description
Unleash sharper throttle response and consistent performance on your Royal Enfield Himalayan 450 or Guerrilla 450 with the BMC FM01210 High-Performance Air Filter — a direct-fit upgrade engineered for riders who expect measurable improvement, not marketing noise.
Designed specifically for the Royal Enfield Himalayan 450 and Guerrilla 450, the BMC FM01210 replaces your stock paper filter with a reusable, performance-focused filtration system that improves airflow while maintaining effective dust protection. It installs directly into the OE airbox without modification, preserving factory fitment and sealing integrity.
Advanced Multi-Layer Oiled Cotton Filtration
At the core of the BMC FM01210 Air Filter is BMC’s proven multi-layered oiled cotton gauze construction. The cotton layers are saturated with low-viscosity oil that traps airborne particles while allowing a higher volume of clean air to pass through compared to conventional paper filters.
BMC states that this filtration system is capable of capturing particles as small as 7 microns, helping protect the engine from dust and contaminants during highway touring, urban commuting, and off-road riding conditions.
Unlike disposable filters, this design is washable and reusable, making it a long-term performance component rather than a routine replacement item. For riders covering high mileage annually, this significantly reduces recurring maintenance costs.
Full Moulding Technology for Structural Strength
The FM01210 uses BMC’s Full Moulding technology, which creates a seamless rubber frame structure without glued joints. This eliminates weak bonding points commonly found in lower-grade filters.
The result is improved structural integrity under:
-
Heat cycles
-
Engine vibration
-
Off-road stress
-
Long-term usage
The rubber sealing edge maintains proper contact inside the factory airbox, preventing air leaks and ensuring all intake air passes through the filtration medium. A secure seal is critical, because even small air gaps can compromise filtration efficiency.
Optimised Airflow for Real-World Riding
Airflow efficiency directly influences throttle response and combustion stability. The BMC FM01210 for Himalayan 450 / Guerrilla 450 is engineered to reduce intake restriction while maintaining filtration balance.
Riders typically choose this filter for:
-
Sharper throttle pickup
-
Smoother mid-range response
-
More consistent power delivery
-
Improved intake breathing
On long highway stretches, smoother airflow contributes to stable cruising performance. In city traffic, improved intake response can make throttle transitions feel more controlled and predictable.
This is not marketed as a race-only component. It is positioned as a performance-oriented OE replacement upgrade suitable for daily riding, touring, and mixed terrain use.
Epoxy-Coated Aluminium Mesh Support
The filtration element is reinforced by an epoxy-coated aluminium mesh, designed to resist oxidation from humidity and fuel vapours. This protective coating helps preserve structural integrity over time, especially in climates with high moisture levels.
The mesh provides rigidity while maintaining consistent airflow channels. Combined with the moulded rubber frame, the structure resists deformation and maintains proper fitment even after repeated cleaning cycles.
Washable & Reusable – Long-Term Ownership Advantage
The BMC FM01210 High-Performance Air Filter is built for the service life of the motorcycle when maintained correctly. Unlike paper filters that must be replaced periodically, this unit can be cleaned and re-oiled at scheduled intervals.
Recommended maintenance includes:
-
Cleaning with an approved air filter cleaning solution
-
Allowing complete drying before re-oiling
-
Applying appropriate filter oil evenly across the cotton layers
With proper care, performance consistency is maintained over extended usage.
Direct Fitment for Himalayan 450 & Guerrilla 450
This air filter is manufactured specifically for:
It installs inside the factory airbox without modification. No trimming, no cutting, and no structural changes are required.
Correct installation and sealing should always be verified before riding. Ensure the airbox is properly secured after replacement.
