Sprint Filter F1-85-SBK Air Filter Honda CBR 1000 RR-R SC82 (2020-2026) R177S

The Sprint Filter F1-85-SBK R177S is the WorldSBK-specification air filter engineered specifically for the Honda CBR 1000 RR-R SC82 (2020–2026). Built around a carbon fibre frame with an enlarged filter surface, this is the filter that factory MotoGP and World Superbike race teams trust — and it is now available for both track and road use without any ECU remapping required.

Key Features

• Triple the airflow of the standard P08 filter, delivering a measurable gain in engine performance and throttle response.
• Carbon fibre frame construction increases rigidity and reduces weight while expanding the available filter surface area.
• Precision polyester mesh with a wire diameter of just 22 microns filters particles down to 85 microns, keeping the engine protected without choking intake flow.
• World's only waterproof filter of its type — a proprietary Sprint Filter technology that performs reliably under the most extreme racing and wet-weather conditions.
• Near zero-maintenance upkeep: clean with compressed air alone, no expensive filter oils or chemical treatments needed.
• Polyester filter medium retains its structural integrity and filtration performance over years of hard use with no measurable degradation.
• Developed and proven by factory race teams across MotoGP, Moto3 and World SBK, backed by over 65 years of Sprint Filter manufacturing expertise.

Premium Construction and Race Pedigree

What sets the F1-85-SBK apart from conventional high-flow filters is not just the numbers — it is the material quality that underpins them. The carbon fibre frame is not decorative; it provides the structural stiffness needed to maintain consistent airbox sealing under the pressure differentials created by a litre-class inline-four at full throttle. The enlarged surface area of the filter medium means the engine breathes more freely at every point in the rev range, not just at peak power.

Sprint Filter's polyester weave is manufactured to tolerances that most competitors do not attempt. The 22-micron wire diameter is chosen to balance filtration efficiency against flow resistance, and because polyester does not absorb water or oil the way cotton gauze does, the filter's characteristics remain stable whether the air is cold and dry at a circuit or warm and humid on a Sunday road ride. The waterproofing technology is unique to Sprint Filter — no other production air filter in this category offers the same level of protection against ingested water.

Road and Track Versatility

The F1-85-SBK is classified as a WorldSBK-spec component, yet it fits the CBR 1000 RR-R SC82 as a direct replacement for the factory airbox filter with no modification. No ECU tune is required to see the benefit, although riders running a power commander or flash tune will find the increased airflow pairs particularly well with fuelling adjustments. The near-maintenance-free design is especially practical for track-day riders who need reliable performance session after session without time-consuming filter servicing between runs.
