KTM 250 EXC SIX Days [2002-2003] - Wheel membrane block - KTM 250/300EXC

BOYESEN wheel membrane block for KTM 250 EXC SIX Days

The BOYESEN wheel membrane block is developed as a model-specific intake system for the KTM 250 EXC SIX Days from the 2002-2003 model year range. Its design combines an optimized internal surface with a 4-way diffuser to specifically guide the intake air flows and avoid pressure losses.

Function and construction

• Membrane block made of 100% aluminum
• Optimized interior surfaces according to the principle of Aerodynamic Surface Optimization
• 4-way diffuser to optimize airflows
• Model-specific membrane plates with variable flexibility
• Aerospace-grade carbon membrane plates
• Rubber-coated and hydrocarbon-resistant membrane plates

The variable flexibility of the membrane plates supports the model-specific tuning of the intake system. The hydrocarbon-resistant design is designed for a longer seal life. The multi-stage opening behavior of the membrane plates is part of BOYESEN's Multi-Stage Reed Timing technology.

Assembly and scope of delivery

The scope of delivery includes the intake manifold and fastening clamps. The membrane block is intended for direct assembly without modification.

Vehicle assignment

Suitable for the KTM 250 EXC SIX Days, built in 2002-2003. The model-specific design of the intake system supports efficient intake air routing and better pulling power.
