Sprint Filter SM245S F1-85 air filter

The facts.

DescriptionThe whole story▼

Of the four machines that share this airbox, the V-Strom 800DE is the one where the honest advice is to look elsewhere in the catalogue. It is built to leave the tarmac, and the air it draws on gravel and a dry summer verge carries a load a racing medium was never meant to sort. The Sprint Filter P08 F1-85 is the fast end of the range: 15,000 litres per square metre per second, against 5,050 through 80 microns on the standard P08. The 85 is not a pore size and the racing cloth filters no worse than the P08, but more flow is not what an engine expected to reach a high mileage in dust, without ever being opened, needs. For an 800DE the interesting part of the range lies the other way — the P14, at 14 microns and 1,800 l/m²/sec.

Key Features

  • Racing medium: 15,000 l/m²/sec, built for flow rather than for fine dust
  • Against the standard 80 micron P08 and its 5,050 l/m²/sec: more flow, which this bike does not need
  • For dust the range runs the other way: P14 at 14 microns and 1,800 l/m²/sec
  • Dry polyester whichever medium you pick — no filter oil to carry or source on tour
  • Cleaned with compressed air and used again instead of replaced
  • Two years of warranty, counted from the day it was bought

Wear you never get to measure

Dust does not damage an engine in one event. It adds up: every abrasive particle reaching the bores and rings takes its share, and nothing on the dashboard reports the balance. That is what makes the medium a real decision on a travel enduro. A racing engine carries the same debt but has a settlement date — the next overhaul, scheduled by running hours, which resets the account and shows what the intake let through. The 800DE has no such appointment in its plan. It is bought to cover long distances between services, and the sensible policy for such an engine is to let as little through as the airflow can spare.

Where this element would belong

There is a version of this bike for which the F1-85 makes sense: an 800DE built as a competition machine, run on closed ground, with an engine serviced by running hours. That is a small minority; everything else points down the range. For mixed use — tarmac stages with gravel where the road runs out — the standard P08 at 80 microns and 5,050 l/m²/sec is the balanced answer. Where dust is the rule rather than the exception, the P14 trades flow for retention on purpose, and the T12 goes further at 7 microns and 560 for desert conditions. The housing takes all of them, so the choice can be revisited when the riding changes.

Care and cleaning

Whichever medium ends up in the airbox, the routine is the one the SM245S F1-85 asks for: compressed air on the clean side, worked outwards, as often as a dusty stage makes it worthwhile. Where air will not do, lukewarm water and a mild detergent will, rinsed until clear. Then open air until it is dry through — never heat, never a flame — and back in dry. Nothing is ever oiled.
