Description
If you’re running a RM125 and leaving performance on the table, a restricted intake valve is likely the culprit. The BOYESEN Radiator Valve eliminates flow restrictions and ensures even fuel-air distribution across all intake ports, translating to sharper throttle response and measurable horsepower gains throughout the entire RPM range. With Boyesen’s proven dual-stage reed design and one-piece aluminum construction, this is a bolt-on upgrade that delivers real results without fabrication headaches.
