Hm CRE 250 R [2005-2007] - Wheel membrane block - Honda CR250R

BOYESEN wheel membrane block for Hm CRE 250 R

The BOYESEN wheel membrane block is developed as a model-specific intake system for the Hm CRE 250 R from the 2005-2007 model year range. Its construction combines an optimized internal surface with a 4-way diffuser that supports intake air flows and reduces pressure losses.

Function and construction

The block is made of 100% aluminum. The inner surfaces are designed to guide the intake air in a streamlined manner. Model-specific membrane plates with variable flexibility and several opening levels support an attractive interaction of intake, torque and pulling power.

• 4-way diffuser to optimize airflows
• Aerospace-grade carbon membrane plates
• Rubber-coated, hydrocarbon-resistant membrane plates
• Hydrocarbon resistant materials for longer seal life
• Intake nozzle and fastening clamps included in delivery

Technical features

BOYESEN relies on aerodynamic surface optimization, model-specific membrane plates and multi-stage reed timing for this intake system. The membrane plates open in several stages and are tailored to the respective motorcycle model. This supports efficient intake as well as consistent power and torque development.

Vehicle assignment and assembly

Suitable for Hm CRE 250 R, built between 2005 and 2007. The membrane block is intended for direct assembly without modification. Intake connection and fastening clamps are included in the scope of delivery.
