Yamaha YZ 125 (CE 09) [2002] - Wheel membrane block - Yamaha YZ125

BOYESEN wheel membrane block for Yamaha YZ 125

The BOYESEN wheel membrane block was developed model-specifically for the Yamaha YZ 125 built in 2002. Its intake system is designed to guide the intake air in a targeted manner and thereby optimize the engine's power, torque and elasticity.

Structure and function

The membrane block is made of 100% aluminum and has an optimized inner surface. A 4-way diffuser supports the guidance of the air flows and helps to avoid pressure losses in the intake area. The membrane plates have variable flexibility and are model-specific.

• Aerospace-grade carbon membrane plates
• Rubber-coated, hydrocarbon-resistant membrane plates
• Model-specific design for coordinated membrane movement
• Intake nozzle and fastening clamps included in delivery
• Direct assembly without modification

Vehicle assignment

Suitable for the Yamaha YZ 125 (CE 09), built in 2002. The vehicle assignment refers to this entire year of construction.

Factual information

The hydrocarbon-resistant design of the coated membrane plates supports a longer service life of the seals. The intake system was developed for competition use and optimizes the intake air flows for better pulling power on the Yamaha YZ 125.
