V-FORCE V-Force 4R Reed Valve for Kawasaki KX125 (manufacturer reference V4R13G): an intake part designed for demanding motocross riders. Designed by V-FORCE for 2-stroke engines, this reed valve improves the efficiency of the intake system compared to the original reeds to optimise throttle response and airflow at the cylinder inlet.

• Carbon fibre reeds, pre-curved for optimal sealing
• Widened reed valve box and combined reed petal tail increased by 10.5% to enhance airflow
• Aerodynamic profile at the end to increase the speed of air entering the external intake ports
• Extended reed stop to gradually reduce stress at the end of the stroke and prolong lifespan
• Overmoulded rubber at the tips of the petals for better wear resistance
• Collector, box and air deflector specifically designed for the V-Force 4R system

Suitable for the world of motocross and demanding riding, this V-Force 4R reed valve is ideal for performance and reliability-oriented modifications on the Kawasaki KX125. Manufacturer reference: V4R13G. Check compatibility with your model year before installation.
