The facts.
DescriptionThe whole story▼
A cruiser spends its life in the lower half of the rev range. The Calibro and its Bagger version are built for relaxed riding, torque from low down and long stretches at a steady pace, and that changes how an air filter's specification should be read. Flow ratings describe what happens at full throttle, a state a cruiser rarely visits. What matters on a Calibro is everything else: how the element behaves over years of ownership, and what it takes to keep it in condition.
Key Features
- Dry single-layer woven polyester, 80 µm, fibres from 22 µm
- 5,050 l/m²/sec of rated flow, well beyond what a cruiser draws at a steady pace
- 93.13 % of 100-micron particles retained; four-layer oiled cotton holds 76.42 %
- About double the filtering surface of other performance filters
- Fits the series airbox of the Calibro and Calibro Bagger directly, with no remap
- Never oiled, washable and reusable, two-year warranty
An ownership part, not a performance part
Nobody fits a filter to a Calibro to make it faster, and that is just as well: no element in an unmodified airbox makes a series engine stronger. The case for the P08 is ownership. Sprint Filter designs it to last the life of the motorcycle, so the paper panel that would otherwise be bought at service after service is replaced once and then cleaned. The doubled surface spreads what it collects, so resistance rises slowly between cleans. On a bike kept for many years, that adds up to fewer parts and an intake whose condition is always known.
Touring with the Bagger
A Bagger is built for distance, and long trips sometimes run through dusty regions or summer road works. For riders whose routes are regularly like that, Sprint Filter also lists a P14 for the Calibro, a 14-micron nonwoven that filters finer at the cost of flow, a cost a low-revving cruiser hardly notices. The P08 F1-85 racing weave is listed as well, but on a cruiser it has nothing to offer. For the Calibro on ordinary roads, the standard P08 is the right element.
Care and cleaning
Remove SM297S during the service and clean it with compressed air from the engine side outwards. If road film has bonded to the weave, wash it in lukewarm water with a little mild detergent and rinse until clean. Dry it at room temperature with air moving around it, never on a heater, with a heat gun or near a flame, and fit it back dry and untreated. The maintenance sheet is in the Downloads tab.
