YAMAHA YZ 250 [2024-2027] - Wheel membrane block - Yamaha YZ250

BOYESEN wheel membrane block for the Yamaha YZ 250

The BOYESEN wheel membrane block is developed as a model-specific intake system for the Yamaha YZ 250 from the 2024-2027 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 reduce pressure losses.

Function and construction

• Membrane block made of 100% aluminum with optimized inner surface
• 4-way diffuser to optimize airflows
• Model-specific membrane plates with variable flexibility
• Aerospace-grade carbon membrane plates
• Rubber-coated, hydrocarbon-resistant membrane plates for longer seal life
• Technologies such as Aerodynamic Surface Optimization, Model-Specific Reed Petal Tensioning and Multi-Stage Reed Timing support the tuning of the intake system

Assembly and scope of delivery

The intake manifold and the fastening clamps are included in the scope of delivery. The membrane block is intended for direct assembly without modification and thus enables clearly defined installation in the vehicle model developed for it.

Vehicle assignment

Suitable for the YAMAHA YZ 250, years built 2024-2027. The model-specific design of the membrane plates and the inlet system is tailored to this entire year of manufacture.

Characteristics of the inlet system

The design was developed to optimize intake air flows to support the efficiency, performance and pulling power of the Yamaha YZ 250. The combination of variable membrane plate layout, durable materials and flow-optimized geometry is aimed at drivers looking for a vehicle-specific intake system for competition use.
