Ventilček Vforce 4RHONDA 125 CR 125 R (JE01) - 1987 - 2000Ref : VF00005A / 1009777

Reed valve V-Force 4R for Honda CR125R (manufacturer ref. V4R01D)

Designed by V-FORCE for 2-stroke motocross engines, the V-Force 4R modernizes the intake for a livelier engine response. Its pre-curved carbon fiber reeds ensure better sealing and a more consistent intake valve response. The entire assembly is designed to improve airflow and gas management without altering the original cylinder architecture.

Key features:

• Pre-curved carbon fiber reeds for optimized sealing.
• Wider box and combined reed tail increased by 10.5% to enhance airflow.
• Aerodynamic profile at the end to increase airspeed at the external intake ports.
• Extended reed stop for a gradual reduction of stresses at the end of the stroke and increased service life.
• Front area of the central reed reduced by 15.6% for a sharper profile and better internal circulation.
• Overmolded rubber on the tips of the reeds to limit wear at the seat contact.
• Collector, box, and deflector specifically designed for the V-Force 4R system.

Ideal for motocross riders looking to refine the intake and responsiveness of their CR125R JE01 (1998–2000). Replaces the original box and integrates into intake modifications without unverified promises: it optimizes airflow and reed stability for a more consistent 2-stroke operation.
