Boyesen Supercooler Water Pump Kit (Orange) — KTM / Husqvarna / GasGas 125-300cc

Boyesen Supercooler Water Pump Kit — KTM / Husqvarna / GasGas 125-300cc (TBI)

Product Description

Keep your late-model fuel-injected two-stroke operating at peak efficiency with the Boyesen Supercooler Water Pump Kit. Precision-engineered as an upgraded cast-aluminum cover and impeller combination, this kit provides a direct, Factory Quality fit for modern KTM, Husqvarna, and GasGas 125cc to 300cc machines. Finished in a rugged, powder-coated orange, the Supercooler eliminates cooling bottlenecks to maximize horsepower and shield your engine from heat-induced power fade.

The secret to the Boyesen Supercooler lies in its proprietary Nautilus-style impeller and hydromechanically optimized cover interior. Unlike stock setups that cause coolant cavitation and turbulent flow restrictions, Boyesen’s hydrodynamic architecture actively smooths and accelerates fluid movement across all RPM ranges. By drastically increasing coolant flow velocity, your engine maintains a significantly lower and more consistent operating temperature, ultimately protecting critical top-end components and extending overall engine life.

Top Features: Boyesen Supercooler Kit

• Hydrodynamic internal cover design dramatically increases fluid flow velocity to reduce engine operating temperatures.
• Investment-cast aluminum construction offers superior strength and structural impact resistance over stock covers.
• Patented Nautilus-style impeller maximizes pumping efficiency while preventing high-RPM coolant cavitation.
• Durable powder-coated orange finish provides an aggressive, race-ready look while defending against trail debris.
• Proudly designed, tested, and manufactured in the USA for guaranteed Factory Quality fitment alignment.

Frequently Asked Questions

Q: Does this water pump kit require a different size or non-standard drive gear?
A: No. The Boyesen Supercooler bolts directly up to your existing stock internal water pump shaft and utilizes your original equipment mounting gear setup for a clean install.

Q: Do I need to use a special type of coolant with this high-flow system?
A: While standard high-quality powersports coolants work seamlessly, pairing this kit with a high-performance, silicate-free racing coolant will yield the lowest possible thermal breakdown thresholds.

Expert Pro-Tip: Anytime you open your cooling system or replace a water pump component, always replace the surrounding case gaskets and closely inspect your mechanical water pump shaft seal for tears or scoring. Bleed the cooling system completely upon reassembly by leaning the motorcycle slightly back and forth to purge any trapped air pockets from the radiators.
