This complete replacement airbox allows you to cleanly swap a carbureted two-stroke engine into a modern Honda aluminum chassis. CAD-designed specifically for 2021–2026 CRF450R and 2022–2026 CRF250R frames, it corrects the intake geometry, providing the exact clearance and alignment needed to route a two-stroke air boot directly to the carburetor.
Whether you are dropping in a 125cc, 250cc, or a massive 500cc big-bore engine, this unit eliminates the headache of melting, hacking, or heat-gunning a stock four-stroke airbox.
Key Features:
- Bolt-On Fitment: Drops directly into the modern CRF twin-spar chassis with zero frame modifications required.
- OEM Compatibility: Form-fitted to clear the stock rear shock reservoir and integrates perfectly with your factory mudflap and side panels.
