Yamaha YZ 125 (CE 15) [2005] - Wheel membrane block - Yamaha YZ125

BOYESEN wheel membrane block for Yamaha YZ 125

The BOYESEN wheel membrane block is developed as a model-specific intake system for the Yamaha YZ 125 (CE 15), built in 2005. Its design combines a flow-optimized inner surface with a 4-way diffuser, which specifically supports the air flows and avoids pressure losses.

Function and design features

• The membrane block is made of 100% aluminum.
• The optimized inner surface supports uniform guidance of the intake air.
• The 4-way diffuser is designed to optimize airflow.
• Model-specific membrane plates with variable flexibility enable multiple opening levels.
• The membrane plates are made of aviation-grade carbon.
• The rubber-coated and hydrocarbon-resistant membrane plates are designed for a longer seal life.

Design for the Yamaha YZ 125

Boyesen develops its membrane blocks individually for the respective motorcycle model. This means that this intake system is specifically assigned to the Yamaha YZ 125 (CE 15) built in 2005. The design of the membrane plates and the geometry of the diffuser are tailored to this model.

Technical benefit

The combination of optimized internal surface, 4-way diffuser and variable membrane plate flexibility is designed to optimize intake airflows. With this design, Boyesen aims to improve the efficiency, power, torque and pulling power of the Yamaha YZ 125.
