Yamaha TT-R 125 LW BIG Wheels E (CE 21) [2021] - Wheel membrane block - Yamaha YZ125

BOYESEN wheel membrane block for Yamaha YZ125

The BOYESEN wheel membrane block is a model-specific intake system with design details to optimize the intake air flow. Its inner surfaces are designed for efficient flow guidance, while the integrated 4-way diffuser is intended to reduce pressure losses and improve airflow in the intake area.

Function and execution

• Membrane block made of 100% aluminum
• Optimized inner surface for intake air routing
• 4-way diffuser to optimize airflows
• Model-specific membrane plates with variable flexibility
• Aerospace-grade carbon membrane plates
• Rubber-coated, hydrocarbon-resistant membrane plates

The variable flexibility of the membrane plates is designed for a coordinated opening characteristic. Together with the model-specific design, the membrane block supports controlled suction. The hydrocarbon-resistant design of the coated membrane plates is designed to ensure a longer service life for the seals.

Vehicle assignment

Intended for the Yamaha TT-R 125 LW BIG Wheels E (CE 21), built in 2021.

Factual note

The diaphragm block is part of the BOYESEN inlet system range. The design combines the aluminum block with a 4-way diffuser and model-specific carbon membrane plates for the vehicle assignment mentioned.
