Product Overview
This stator trigger pickup coil is designed as a replacement ignition pickup coil for selected 2004-2005 TRX450R / TRX450ER Sportrax ATV, 4-wheeler, and quad applications.
The pickup coil works with the stator, flywheel, CDI, and ignition system to detect engine timing signals and help trigger spark at the correct moment. A weak, damaged, or failed pickup coil may cause no spark, hard starting, intermittent ignition, misfiring, poor running, or engine stalling.
This replacement pickup coil features a 2-wire design, 5mm / 0.20" mounting hole diameter, 33mm / 1.3" mounting hole distance, and replaces OEM reference number 31120-HP1-003.
Please compare the OEM part number, wire count, mounting hole distance, mounting hole diameter, connector style, wire routing, and product photos with your original pickup coil before ordering.
