- Fits: KTM 450SX-F/XC-F 2016-2019, KTM 500 EXC-F 2017-2019
- By casting a totally new water pump cover, Boyesen was able to maximize the flow through the unit. Boyesen’s design takes advantage of everything from Bernoulli’s Effect to biological studies
- Unlike the stocker, Boyesen’s water inlet has an increasing diameter and artfully curved shape. This is a vast improvement over most stock inlets, which decrease in diameter as they near the impeller and have a 90-degree bend at the pump
- Patented nautilus style impeller for hydrodynamic efficiency, reducing heat, gaining horsepower and extending engine life
- Can reduce engine temperatures by as much as ten degrees
