YAMAHA YZ 125 [2024] - Wheel membrane block - Yamaha YZ125

BOYESEN wheel membrane block for the YAMAHA YZ 125

The BOYESEN wheel membrane block was developed specifically for the YAMAHA YZ 125 built in 2024. Its intake system combines a flow-optimized internal geometry with model-specific membrane plates, thereby supporting efficient intake.

Function and structure

The optimized inner surface and the 4-way diffuser direct the air flows in a targeted manner and help to avoid pressure losses. The membrane plates have variable flexibility and are tailored to the respective motorcycle model. This means that the membrane block is tailored to the requirements of the YAMAHA YZ 125.

• Membrane block made of 100% aluminum
• Optimized internal surface for intake flow
• 4-way diffuser to optimize air flows and avoid pressure losses
• Model-specific membrane plates with variable flexibility
• Aerospace-grade carbon membrane plates
• Rubber-coated, hydrocarbon-resistant membrane plates

Design for competition use

BOYESEN's RC2 membrane blocks are designed for competition use. The design optimizes the intake air flows and supports higher efficiency, performance and better pulling power. The hydrocarbon-resistant design of the membrane plates also contributes to a longer service life of the seals.

Vehicle assignment

Suitable for the YAMAHA YZ 125, built in 2024.
