Wheel Speed / Vehicle Speed Sensor
Wheel Speed / Vehicle Speed Sensor (Hall Effect, Most Common)
ATV Wheel Speed Sensor
Working Principle: A magnetic toothed ring is installed on the wheel hub or transmission output shaft. The Hall probe senses alternating magnetic field changes, generating one pulse signal for each tooth passing by as the wheel rotates.
The pulse frequency corresponds to the vehicle speed. Signals are sent to the instrument cluster to display speed and mileage. The ABS system detects wheel lock-up by comparing speed differences between the four wheels and activates anti-lock braking accordingly.
This sensor has no mechanical contact points, features waterproof and sand-resistant performance, and is suitable for harsh off-road operating conditions.

Use full synthetic high-temperature engine oil and shorten the oil change cycle properly. Clean the air filter to guarantee smooth air intake. Adjust the tire pressure slightly lower than the standard to prevent high-temperature tire burst. Inspect the brake fluid and brake pads, and clean the brake caliper silt. Clear dust inside the CVT transmission box and keep vents unobstructed to avoid belt burning. Polish battery terminals and do not fill the fuel tank full to reserve thermal expansion space. During riding, avoid long-time high thrott...

How to Find ATV Parts as an Overseas Buyer First, collect full vehicle info: VIN, year and model. Take photos of broken parts and measure sizes to get the OEM part number from the official parts catalog for accurate matching. Check local suppliers first.

For special custom brackets or gears, contact suppliers for custom m...
