Sprint Filter P08 Air Filter for Road & Track – Zontes ZT 125-GK (2020–2026) SM276S

Everything a used motorcycle has been through leaves a trace somewhere a buyer can look. Tyres, discs, chain, fasteners, the state of the fluids — all of it is visible in a car park on a Saturday morning. The intake tract is the exception. Nobody unclips an airbox during a viewing, no service stamp describes what was inside it, and the one system where neglect is genuinely cumulative is the one system that never gets inspected. A washable element is the only part of that story a new owner can reset completely on the first afternoon.

Key Features

• Dry woven polyester in one layer: filtration at 80 µm, flow of 5,050 l/m²/sec
• Never oiled, so there is no film upstream of the throttle body or the sensors
• About double the filtering area of other performance filters
• A straight swap for the standard paper panel inside the original case, with no modification and no remap
• Retention measured at 93.13 % on 100-micron particles against 76.42 % for oiled cotton gauze in four layers
• Rated by Sprint Filter for the service life of the motorcycle; warranty runs two years from purchase

The chapter no inspection reaches

A neglected paper cartridge cannot be undone. It is fitted, it loads up, and every gram it eventually failed to catch has already gone through the engine — the receipt for that arrives years later as wear nobody can trace back. Buying a second-hand ZT 125-GK, you have no way of knowing which of those two histories you have. Ten minutes and an air line settle it. Open the case, look at what is in there, clean it, refit it, and from that point the record starts again with you keeping it.

An asset that transfers

The element outlives the ownership. When the machine moves on, the SM276S goes with it, still washable, still the same part, and the next rider inherits a maintenance item that has stopped needing to be bought. It is worth keeping the original panel labelled in a box as well: the change is entirely internal and fully reversible, so a machine can be handed over in either specification. None of this makes an A1 motorcycle quicker — its output is set by the licence class it was homologated for, not by anything in the airbox. What it does is take one line out of the running costs permanently.

Care and cleaning

Blow it through from the inside face outward, so the load retraces its own route instead of being driven deeper into the weave. Anything that will not shift dry comes off with warm water and a mild washing-up liquid; rinse thoroughly, then leave it in moving air until it is completely dry. Heat is the one prohibition without exceptions — no hot air gun, no flame, no radiator — and the element is refitted bare, with no oil or dressing of any kind. The maintenance sheet sits in the Downloads tab.

Fitment & Compatibility

Made for the Zontes ZT 125-GK, 2020 to 2026, as a direct replacement in the standard airbox. Five further Zontes models of 125, 155 and 200 cm³ share the same case and therefore the same element; the full list is in the Fitment tab.
