KTM 250 SX [2004-2016] - Wheel membrane block - KTM/Husqvarna

BOYESEN wheel membrane block for the KTM 250 SX

The BOYESEN wheel membrane block is designed as a model-specific intake system for the KTM 250 SX from the 2004-2016 model year range. Its design combines optimized internal routing with coordinated membrane plates and thereby supports efficient design of the intake air flows.

Structure and function

• The membrane block is made of 100% aluminum.
• The optimized inner surface and the 4-way diffuser serve to guide the air flows and avoid pressure losses.
• The model-specific membrane plates have variable flexibility and are made of aviation-grade carbon.
• Rubber-coated, hydrocarbon-resistant membrane plates support longer seal life.
• The system utilizes several BOYESEN technical development approaches, including Aerodynamic Surface Optimization, Model-Specific Reed Petal Tensioning and Multi-Stage Reed Timing.

Scope of delivery and assembly

The scope of delivery includes the intake manifold and the fastening clamps. The membrane block is intended for direct assembly without modification. It thus offers a clearly assigned solution for revising the intake system on the KTM mentioned.

Vehicle assignment

Suitable for the KTM 250 SX, built between 2004 and 2016.

The membrane plate flexibility and the multi-stage opening characteristics tailored to the KTM 250 SX are designed for optimized intake and better pulling power.
