Sprint Filter P08 Air Filter for Road & Track – Triumph Tiger 1200 Rally /Pro/Explorer (2023–2026) SM256S

Triumph built the Rally by changing what sits below the seat: a larger front wheel, more travel at both ends, more ground clearance, tyres with a block pattern. What sits above it is carried over, and the airbox is part of that. Sprint Filter's catalogue says the same thing in its own way — SM256S is one part number for the Rally and the GT alike. The chassis, then, is where Triumph's off-road specification ends. The filter medium is where a rider can either continue it or decide, honestly, that there is nothing to continue.

Key Features

• One woven layer of polyester, dry from new, with an aperture calibrated to 80 µm
• Rated at 5,050 l/m²/sec, the standard specification for road and track use
• Polyester threads from ø 22 microns — the weave does the filtering, not a pressed paper mat
• About twice the filtering surface of other performance filters, inside the unmodified airbox
• Drops into the standard airbox in the paper panel's place: no modification, no remap
• Never oiled, washable, made to last the life of the motorcycle, two years of warranty from purchase

Capability is not the same as air

Wheels and suspension decide what the machine can cross. They decide nothing about what it breathes while crossing it: the intake sits where it sat on the GT, draws through the same box, and is specified for the same air. For most owners that is the right specification, because most Rally kilometres are still tarmac kilometres — the long approach, the motorway section, the ride home. On that road the P08 is the correct end of the trade. To be plain about what it is not: a drop-in element does not make a standard Tiger 1200 noticeably more powerful. It holds the intake at one known resistance and puts it back there at every clean.

The second element in the catalogue

Sprint Filter lists a T12 for this airbox as well, SM256T12, catalogued for the Rally and the GT alike. The two belong side by side rather than on a ladder. The P08 filters at 80 µm and flows 5,050 l/m²/sec; the T12 is a dry non-woven at 7 µm and 560 l/m²/sec, made for extreme conditions, dust and desert. A finer structure holds back more and lets less through, and that is the whole of it, in both directions — a T12 is not a better filter than a P08. What decides between them is not what the machine could cross, but how much of the air it actually draws comes off loose ground.

Care and cleaning

Take the SM256S out, put compressed air through it from the clean side outwards, and the usual service is finished. Where a gravel week or a salted winter has left more than dust, lukewarm water with a mild detergent will do it: rinse until the water runs clear, then let it dry fully in open air — never with heat, never with a flame. It is refitted dry and never oiled. The maintenance sheet sits in the Downloads tab.

Fitment & Compatibility

Made for the Triumph Tiger 1200 Rally, Rally Pro and Rally Explorer built from 2023 to 2026. The same element covers the Tiger 1200 GT of those years — two machines in total on this part number. Model years are listed in the Fitment tab.
