Description
If you’re running a RM125 two-stroke, intake charge distribution directly impacts how your engine responds and produces power across the rpm band. The Boyesen Radiator Valve optimizes flow velocity and redirects the intake charge evenly to your ports, translating to sharper throttle response and measurable horsepower gains throughout your power delivery. This is the kind of bolt-on efficiency upgrade that serious two-stroke racers rely on to squeeze every advantage out of their build.
