If your GTS is misfiring at idle, stumbling under load, or refusing to start despite a good battery and fresh spark plug, the coil is the first place to look. This high-quality RMS aftermarket replacement restores full high-voltage spark output to your ignition system, ensuring clean, complete combustion across the entire RPM range.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eFull Spark Output:\u003c\/b\u003e Engineered to deliver the correct high-voltage pulse to the spark plug cap, restoring crisp throttle response and eliminating misfires.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eOEM-Spec Winding:\u003c\/b\u003e Internal primary and secondary coil windings matched to Piaggio's original resistance specifications for a true drop-in replacement.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eHeat-Resistant Epoxy Potting:\u003c\/b\u003e Coil internals are sealed in high-temperature epoxy to protect against vibration, moisture ingress, and thermal cycling.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eDirect Connector Match:\u003c\/b\u003e Factory-matched electrical connector plugs directly into the GTS ignition harness — no splicing, adapters, or modifications required.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment Guide\u003c\/h3\u003e\u003cdiv class=\"horizontal-scroll-wrapper\"\u003e\u003cdiv class=\"table-block-component\"\u003e\u003cdiv class=\"table-block has-export-button new-table-style has-scrollbar is-at-scroll-start\"\u003e\u003cdiv class=\"table-content\"\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eEngine Compatibility\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cb\u003eVespa\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd\u003eGTS 250\u003c\/td\u003e\n\u003ctd\u003eAll Years – Quasar 250cc Engine\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cb\u003eVespa\u003c\/b\u003e\u003c\/td\u003e\n\u003ctd\u003eGTS 300 \/ Super \/ GTV\u003c\/td\u003e\n\u003ctd\u003eAll Pre-HPE Years – Quasar 300cc Engine\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003c\/div\u003e\u003c\/div\u003e\u003c\/div\u003e\u003c\/div\u003e\u003ch3\u003eTechnical Specs\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003ePart Number:\u003c\/b\u003e 58120R-AFT\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eReplaces OEM:\u003c\/b\u003e Piaggio \/ Vespa ignition coil for Quasar 250–300cc engines\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eVoltage:\u003c\/b\u003e 12V DC input\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eOutput:\u003c\/b\u003e High-voltage secondary winding (standard CDI\/TCI compatible)\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eConnector:\u003c\/b\u003e Factory-matched multi-pin plug\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cb\u003eManufacturer:\u003c\/b\u003e RMS (Italy)\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cblockquote\u003e\n\u003cp style=\"text-align: left;\"\u003eMaintenance Note:\u003cstrong\u003e Before condemning the coil, always check the spark plug cap resistance (should be ~5kO) and the plug itself. A carbon-tracked or fouled plug can mimic a dead coil by bleeding off the high-voltage pulse before it fires.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003eInstallation Tip:\u003cstrong\u003e The ignition coil on the GTS is tucked behind the left side body panel near the airbox. Remove the panel carefully and disconnect the coil's two-pin connector and the plug cap before unbolting the coil bracket — it's a 10-minute job with the right trim tools.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003ePro Tip:\u003cstrong\u003e When reinstalling, apply a small amount of dielectric grease inside the spark plug cap before pressing it onto the plug.
