YAMAHA YZ 250 [1996] - Wheel diaphragm block - Yamaha YZ250

BOYESEN wheel membrane block for the Yamaha YZ 250

The BOYESEN wheel membrane block was developed model-specifically for the Yamaha YZ 250 built in 1996. Its intake system combines an optimized internal surface with a 4-way diffuser that supports air flows and reduces pressure losses in the intake area. As a result, the diaphragm block is designed for responsive intake behavior as well as the optimization of power, torque and elasticity.

Technical features

• 100% aluminum diaphragm block
• Optimized inner surface for the intake area
• 4-way diffuser to guide air flows
• Model-specific membrane plates with variable flexibility
• Aerospace-grade carbon membrane plates
• Rubber-coated and hydrocarbon-resistant membrane plates
• Multi-stage opening characteristics of the membrane plates

Assembly and scope of delivery

The intake manifold and the fastening clamps are included in the scope of delivery. The diaphragm block is designed for direct assembly without modification, allowing replacement of the intake system with the included components.

Vehicle assignment

Suitable for the YAMAHA YZ 250, built in 1996.

The hydrocarbon-resistant coating on the membrane plates supports a longer service life for the seals. The design of the intake system aims to make the intake air flows more efficient and to improve the pulling power of the Yamaha YZ 250 in the respective area of ​​application.
