FANTIC XX 125 [2021-2026] - Wheel membrane block - Yamaha YZ125

BOYESEN wheel membrane block for FANTIC XX 125

The BOYESEN wheel membrane block is a model-specific intake system for the FANTIC XX 125. Its design combines an optimized inner surface with a 4-way diffuser that supports the intake air flow and reduces pressure losses. As a result, the diaphragm block is designed to optimize the engine's response as well as torque, elasticity and performance in the usable speed range.

Function and construction

• Block made of 100% aluminum for a stable design.
• Optimized internal surface to support consistent intake air flows.
• 4-way diffuser to optimize air flow and avoid pressure losses.
• Model-specific membrane plates with variable flexibility.
• Aerospace-grade carbon membrane plates.
• Rubber-coated, hydrocarbon-resistant membrane plates for longer seal life.

Technical features

BOYESEN develops its membrane blocks individually for the respective motorcycle model. This inlet system combines several technical approaches: optimization of the internal surfaces, model-specific membrane plates, hydrocarbon-resistant materials and several opening levels of the membrane plates. This design supports controlled airflow and improved pulling power.

Vehicle assignment

Suitable for the FANTIC XX 125, built between 2021 and 2026.

Factual note

The design is tailored to the vehicle assignment mentioned. Before ordering, the existing inlet system should be compared with the product design.
