Upgrade the intake performance of your Kawasaki KX125 with Boyesen 691 dual-stage motorcycle reeds. Designed for riders seeking improved throttle response and stronger engine performance, these replacement reed valves use a two-stage design to help optimize airflow across a broad range of operating conditions.
The Boyesen 691 reed set opens and closes faster than conventional reeds, helping deliver greater low-pressure response during low-throttle operation. Increased velocity and flow area can support improved power delivery, while the durable construction promotes longer overall service life. The design also helps protect the engine because a broken reed is engineered not to cause internal engine damage.
These Boyesen motorcycle reeds are manufactured for direct fitment on select Kawasaki KX125 applications. They fit the 1999 and 2000 Kawasaki KX125. Verify the motorcycle model and year before installation to ensure proper compatibility. Manufacturer part number 691 and vendor part number 59-7691 identify this application-specific replacement component.
