CuraceQ Motorcycle Radiator Cooling Fan 12V 4-inch for NC250 & 150–300cc — 7-Blade High-Flow, Universal Mount

CuraceQ's 12V DC 4-inch motorcycle radiator cooling fan is a compact, bolt-on thermal fan designed to lower engine-bay temperatures on NC250, 150–300cc ATVs, dirt bikes and other small water-cooled machines.

This compact electric fan delivers focused airflow where it matters most — across radiators, intercoolers or other hot components — and arrives with a simple installation kit for DIY fitting. Built from reinforced polypropylene and driven by a high-efficiency 12V motor, the unit is sized for small-displacement motorcycles, mini bikes, karts and UTVs that need auxiliary cooling without heavy-duty hardware.

How does this fan improve cooling on small-displacement bikes and ATVs?

The CuraceQ fan increases airflow through tight engine compartments and over coolant cores when stock airflow is insufficient, such as in slow traffic or off-road crawls. Its 7-blade design and up to 3500 RPM motor create a concentrated air stream that helps remove heat from radiators and nearby components quickly.

• 4-inch blade diameter with seven blades for compact, high-velocity airflow
• 12V DC motor achieving speeds up to 3500 RPM
• Targets radiator, intercooler and adjacent hot components
• Ideal for low-speed scenarios where passive airflow is limited

Will it fit my NC250, 150–250cc ATV or similar machines?

The fan is made for broad compatibility with many Japanese and general-market models — including Honda, Yamaha, Kawasaki and Suzuki machines — and fits a wide range of 150–300cc water-cooled engines. Always check the product images and measure mounting clearances and electrical connections before purchase to confirm fitment.

• Designed for NC250 and other 150–300cc water-cooled engines
• Compatible with ATVs, mini bikes, dirt bikes, karts and UTVs
• Includes a universal installation kit for flexible mounting options
• Verify dimensions and clearance against your vehicle prior to installation

How durable and weatherproof is the CuraceQ cooling fan?

The housing and blades are molded from high-strength polypropylene and selected materials to resist heat, corrosion and everyday wear. Its lightweight yet robust build helps maintain consistent operation in dusty, wet or off-road conditions typical for small motorcycles and ATVs.

• High-strength polypropylene construction for heat and corrosion resistance
• Lightweight design reduces strain on mounting points
• Engineered to perform reliably in demanding riding environments
• Sealed motor assembly helps protect internal components

How simple is installation and daily operation?

The CuraceQ fan ships with a full installation kit for straightforward DIY mounting, wiring and operation without specialized tools. Once installed the fan’s smart start/stop function runs automatically, so you don’t need to manually switch it on when temperatures rise.

• Complete installation kit included for easy DIY setup
• Smart start/stop wiring harness enables automatic operation
• Mounting hardware supports several bracket locations and angles
• Basic electrical wiring knowledge recommended for secure connection

Who is this for: Riders and small-vehicle owners who need targeted, reliable auxiliary cooling for water-cooled 150–300cc engines will find the CuraceQ 12V 4-inch radiator fan useful. It’s aimed at hobbyists, off-road enthusiasts and commuters who want a compact, durable fan that’s easy to fit on NC250s, ATVs, dirt bikes, mini bikes, karts and UTVs to reduce hot-spot temperatures and help maintain consistent performance under load.
