Yamaha 125 DTLC Airbox Sleeve – 3D-Printed TPU Refabrication by AEB Development, Lifetime Warranty

The Manchon de boîte à air is transformed into a precision part for Yamaha two-stroke engines with a 3D-printed TPU sleeve that restores a perfect seal and smooths the air path. Designed by AEB Development, this sleeve is built to last, backed by a lifetime warranty, and engineered to enhance the way your Yamaha breathes at every twist of the throttle.

Technical specifications and Yamaha compatibility

• Material: TPU, 3D-printed with controlled tolerances for consistent fit and sealing
• Finish: precision surface for repeatable seating against the airbox and intake boot
• Compatibility: Yamaha 125 DTLC; designed to fit the standard airbox footprint on Yamaha two-stroke models with similar intake geometry
• Durability: resistant to heat, fuel blends and oil typical of two-stroke combustion
• Warranty: lifetime guarantee on material and workmanship

Benefits for Yamaha two-stroke engines

Replacing worn or ill-fitting airbox sleeves restores air-tight integrity and improves intake efficiency. With a cleaner seal and a more direct air path, you get stronger low-to-mid-range torque, crisper throttle response, and more predictable engine behavior—exactly what a prepared Yamaha needs to feel alive on the back road.

• Enhanced air intake seal eliminates leaks and erratic idling
• Improved throttle response and usable torque for acceleration
• More consistent air flow to the carburetor, cylinder head and piston zone
• Supports reliable engine preparation without compromises to reliability

Installation tips for Yamaha setups

Designed for straightforward replacement, this sleeve plugs into the airbox with minimal fuss. Steps:

• Clean airbox surfaces and verify airbox boot diameter before install
• Align sleeve and press evenly for a uniform seal
• If needed, gently warm the TPU to ease seating; avoid forcing beyond mechanical limits

Materials

• TPU composition offers elasticity, abrasion resistance, and fuel tolerance suitable for airbox environments
• 3D fabrication ensures tight dimensional control for repeatable results

Compatibility and fitment details for Yamaha motorcycles

Specifically engineered for the Yamaha 125 DTLC, with broad compatibility to other Yamaha two-stroke models sharing a similar airbox interface. For models like DTR, TZR, or other DT variants, confirm airbox boot diameter and intake geometry to ensure optimal fit before purchase.
