Motocross and enduro sensors - precise control of engine and driving parameters

Sensors category is for MX/enduro/off-road riders and mechanics who want clean, reliable data from the bike’s engine and chassis systems. We sell replacement and upgrade sensors that feed the ECU and ignition with accurate signals, helping solve hard starting, random stalling, bogging on throttle, and inconsistent idle. Fresh sensors also support stable fueling and timing, so your bike pulls smoothly whether you’re hammering sand whoops or picking through a tight, hot singletrack. If your dash throws fault codes, the fan won’t trigger, or the bike feels “off” despite new plugs and filters, a tired sensor is often the missing piece. When choosing a sensor, start with fit and compatibility: match make/model/year and verify OEM part numbers and connector type (2-pin/3-pin, locking tab, harness length). Next, pick the correct sensor type for the job—TPS, crank/cam position, MAP, IAT, coolant temp, O2/lamda, speed/gear, or fan switch—because symptoms can overlap. Consider riding conditions: mud, pressure washing, and deep water crossings demand sealed connectors and robust housings. Finally, think maintenance: check wiring routing, heat shielding near the header, and that the sensor’s mounting surface and O-rings are clean to avoid false readings. Common mistakes are chasing jets/maps while ignoring intermittent wiring, or reusing cracked grommets that let water into the plug. Replace sensors if you see corrosion on pins, damaged insulation, unstable live readings, or recurring codes after clearing. Always inspect grounds and the harness before blaming the ECU. Tip: Before swapping a sensor, clean the connector with contact cleaner, dry it fully, then apply a thin layer of dielectric grease to keep mud and water out.
