Description
If you’re running a KX85/100 or RM100, intake efficiency directly impacts throttle response and peak horsepower. The BOYESEN Radiator Valve optimizes charge distribution across intake ports while maintaining consistent flow velocity, translating to sharper power delivery and measurable torque gains throughout the RPM range.
