Yamaha YZ 250 (CG 08) [2000-2001] - Wheel membrane block - Yamaha YZ250

BOYESEN wheel membrane block for the Yamaha YZ 250

The BOYESEN wheel membrane block was developed for the Yamaha YZ 250 (CG 08) from the 2000-2001 model year range. Its design combines a flow-optimized inner surface with a 4-way diffuser to direct the intake air in a targeted manner and avoid pressure losses.

Function and construction

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

The model-specific design of the membrane plates is tailored to the intake system of the Yamaha YZ 250. The variable flexibility supports the adaptation of the membrane behavior to the requirements of the engine. The hydrocarbon-resistant design of the coating contributes to a longer service life of the seals.

Assembly and scope of delivery

The intake manifold and the fastening clamps are included in the scope of delivery. Assembly is direct and without modification.

Vehicle assignment

Suitable for Yamaha YZ 250 (CG 08), built between 2000 and 2001.
