TWIN AIR Air Filter - 156017: a component designed for motocross competition, stemming from Twin Air's expertise. Rigorous manufacturing and selected materials provide a two-layer filtration that combines protection against impurities and controlled airflow — qualities praised by many championship riders.

• Double foam: a first airy layer traps dust, sand, and large debris, while the second, denser layer stops fine particles while allowing airflow.
• Specific Twin Air adhesive: ensures the cohesion of the foams and resists solvents and petrol, for increased durability in the airbox.
• Optimised format: slightly smaller than the original element to increase the available volume in the airbox and promote airflow.
• Exclusive breathable seal: maximises the contact surface with the filter housing to limit lateral infiltrations.
• Bonded assembly between the casings: eliminates cavities where dust and impurities could settle.
• Version: Standard

Compatibility (examples): SHERCO ST 3.2 F 2011, SHERCO ST 2.5 2011, SHERCO ST 1.25 2011. Ideal for motocross/enduro practices where robust filtration and reliable airflow are essential for the engine's proper functioning.
