Boyesen HyFlow — Water Pump Cover (WPC-12DM)
Specializing in motocross, Boyesen offers this magnesium water pump cover designed to optimize the hydraulic behavior of the cooling circuit. Thanks to the Opti-Form finishing process, the internal surfaces and channels are smoothed to limit "pinch points" and sharp edges that typically hinder flow within the original cases.
The result: a more consistent flow of coolant to the engine, better fluid distribution in the cylinder, and improved thermal management during prolonged efforts or in hot and muddy conditions. Designed for demanding riders, this cover enhances the efficiency of coolant reinjection into the engine without claiming unverified gains.
