Upgrade the intake performance of your 2001 or 2002 Yamaha YZ125 with Boyesen 697 Dual-Stage Reeds. Designed as a direct-fit replacement for the original reed system, these motorcycle reeds help improve throttle response, airflow, and engine performance without requiring extensive modifications. The dual-stage design uses reed petals that respond progressively to changing engine demands, supporting smoother operation across a broad range of riding conditions.
Boyesen 697 reeds are engineered to open and close faster than standard reeds, helping deliver greater low-pressure response during low-throttle operation. Increased velocity and flow area can contribute to improved air-fuel delivery and stronger overall engine performance. This makes them a practical choice for riders seeking sharper response and improved power from a Yamaha YZ125 while maintaining a straightforward installation.
Fitment: Fits 2001 Yamaha YZ125 and 2002 Yamaha YZ125. Manufactured by Boyesen, part number 697, these reeds are built for durability and extended service life. Their construction is also designed to help prevent engine damage if a reed breaks, providing added protection compared with conventional reed designs. Confirm vehicle fitment before installation and follow the motorcycle manufacturer's service procedures.
