Sprint Filter P08 Air Filter for WorldSBK Racing – MV Agusta Brutale RR (2019–2026) R189S-SBK

Nobody should buy this part without asking the awkward question first, so here it is. R189S-SBK is a race-specification element and it costs several times what an ordinary Sprint Filter panel for a road MV costs. A registered Brutale RR ridden on public roads will not go noticeably faster with it fitted. That is not a caveat buried in small print — it is the honest starting point, and everything else worth saying here has to survive it.

Key Features

• Race-specification frame and mounting, supplied ready to drop into the series housing
• Single layer of dry polyester — no oil, so nothing can migrate onto the sensors reading the incoming air
• Rated at 80 µm and 5,050 l/m²/sec; the same kit exists with the F1-85 cloth at 85 µm and 15,000
• Roughly twice the working area of a typical performance filter, folded into the standard outline
• No airbox modification and no mapping change — nothing about the intake is altered
• Washable, specified to last the life of the motorcycle, two-year guarantee

So what does change

Two things, both small and both real. The first is the shape of the restriction curve. Every element takes a slice of the pressure available at the intake, and the slice grows as the element fills with what it has caught. A paper panel does that steadily from the day it goes in until the day it comes out. A washed polyester cloth is returned to its starting condition instead, so the loss stays where it began rather than drifting upward across a service interval. The second is that you stop buying the item. Neither of those is a performance figure, and neither shows on a dyno graph.

Who it actually suits

An owner who takes the RR to circuit days, cleans it in the paddock between sessions and wants the intake in a known state each time out. Somebody riding a naked bike, which pulls in whatever the road throws up with no fairing ahead of the airbox to slow it down, and who would rather wash a filter than order one. And an owner planning a long ownership, because the case for this part is made over years rather than over a weekend. A rider who does none of those things is better served by the standard panel, and there is nothing wrong with the cheaper answer.

Care and cleaning

Air first, always from the clean side and directed outward — that is the whole of routine maintenance for R189S-SBK. Water is the exception rather than the rule: warm water and a gentle washing-up liquid, used when a gritty spell has left deposits a compressor will not shift. Rinse it through, then let it stand in moving air until it is properly dry. Never apply heat to hurry that along, from a gun, a radiator or a flame, because polyester is what heat destroys first. It goes back in dry, with nothing added. The maintenance sheet sits in the Downloads tab.

Fitment & Compatibility

Made for the airbox of the MV Agusta Brutale RR 1000 built from 2019 to 2026, the longest run of any naked model here. Seven further machines share the element: the Brutale Oro of 2019–2020, the Rush from 2020, and the F4, F4R, F4RR, F4RC and F4RC LH on the faired side.
