Sprint Filter SM305S air filter

The facts.

DescriptionThe whole story▼

The Kove 650 RR arrives with model year 2027, and with a new motorcycle the usual way of checking a filter, asking someone who has already fitted one, does not work yet. Sprint Filter's data sheet for SM305 offers something firmer: a hard reference. It names the original Kove part number, 313-10-04, and gives the element's outer dimensions as 330 × 187 × 24 mm with a weight of 273 g. If the panel you take out of your airbox carries that number or matches that size, you have the right code. That is a better basis for an order than any model name.

Key Features

  • Dry single-layer polyester weave, 80 µm, threads from 22 µm in diameter
  • 5,050 l/m²/sec of rated flow through clean material
  • Replaces the original Kove element 313-10-04 directly, no airbox modification, no remap
  • Outer dimensions 330 × 187 × 24 mm and 273 g, according to Sprint Filter's data sheet
  • About double the filtering surface of other performance filters
  • Never oiled, washable and reusable, two-year warranty

A flat panel for a strong engine

Sprint Filter's data sheet lists 124 PS from 650 cc for this motorcycle, a lot of air per minute for a mid-capacity engine. The P08 is Sprint Filter's road and track weave and passes 5,050 l/m²/sec. Even so, it will not make a standard 650 RR stronger; a drop-in element in an unmodified airbox never does, and the 124 PS are the factory figure, not a target this part raises. What it does is hold its restriction steady. Twice the filtering area spreads the same dirt more thinly, and each clean returns the panel to its starting point, where a paper element only ever gets worse until it is replaced.

Which medium for which 650 RR

Two other media are listed for SM305. The P14 nonwoven filters at 14 µm and passes 1,800 l/m²/sec; it costs roughly four fifths of this element and is the right part for long stretches in dusty air, not for clean roads. The P08 F1-85 racing weave passes about three times the flow at a little over two and a half times the price, and it pays off on a 650 RR prepared for the circuit, not on a road bike. No T12 is catalogued for this housing. For a 650 RR that spends its life on tarmac in ordinary air, the panel on this page is the one to order.

Care and cleaning

Blow compressed air through SM305S from the clean side outwards. For oily residue use lukewarm water with a mild detergent and rinse until the water runs clear. Dry it at room temperature, never with heat or flame, and fit it back dry and untreated. The maintenance sheet is in the Downloads tab.
