Reliable fan activation - with a copper thermo sensing element
Copper conducts heat efficiently so the sensing element responds quickly to rising coolant temperatures, closing the circuit to activate the fan. Manufacture follows factory specifications to match expected electrical characteristics and fit.
Accurate temperature response reduces overheating risk and keeps engine cooling consistent during stop-start traffic or slow rides.
Direct fit for BJ250 and BJ300GS - thanks to OEM-matching dimensions
Supplied dimensions of 4.4 x 2.1 cm and listed replacement OEM codes align with original equipment geometry. Threading and terminal positions match the factory style to ensure compatibility.
No custom drilling or adapters required, making replacement quicker for home mechanics and reducing time in the workshop.
Durable construction - with high-quality copper material
High-grade copper resists corrosion and withstands thermal cycling better than lower-grade metals, maintaining contact integrity over time. Production emphasises sturdiness and resistance to wear.
Longer service life can lower the frequency of repeat replacements and keeps the cooling system reliable across seasons.
