POLISPORT AIRBOX YAMAHA YZ125/250 15-21 - BLACK (RESTYLE)

A direct replacement airbox for the Yamaha YZ125 and YZ250, made by Polisport as a faithful replica of the standard OEM item. It suits 2015-2021 models and comes in black.

It also opens up a popular upgrade path for older bikes: the airbox can be retro-fitted to 2002-2014 YZ125 and YZ250 models, allowing the newer Re-Style plastics to be fitted to an earlier chassis.

Suited to riders replacing a cracked, warped or fatigued airbox after a crash or a few hard seasons, and to anyone converting an older two-stroke to the restyled bodywork.

Fit using your bike's standard airbox fasteners, grommets and mounting hardware; transfer the air filter cage and any subframe rubbers from the old airbox.
Check that the intake boot and filter seal fully seat against the airbox before riding — an air leak past the filter will let dirt into the engine.
Grease the filter sealing flange as you normally would when refitting the air filter, and wipe the flange clean each time the filter comes out.
When retro-fitting to a 2002-2014 YZ125/YZ250, you will also need the matching Re-Style plastics; check subframe and seat alignment before final tightening.
Clean with warm water and mild detergent and a soft cloth or sponge. Avoid petrol, brake cleaner and other strong solvents, which can craze or weaken the plastic.
Do not aim a pressure washer directly at the intake or filter opening; block the intake with an airbox cover or clean rag before washing the bike.
Dry the airbox and drain any water from the bottom of the box before refitting the filter.
Do not overtighten mounting bolts — snug them evenly to avoid distorting or cracking the mounting points.
Inspect for cracks, stress marks and loose mounts after crashes and at regular service intervals, particularly around the fastener points.
Store spare or removed plastics flat, out of direct sunlight and away from heat sources.
