{"product_id":"digital-internal-rotor-ignition-kit","title":"Digital Internal Rotor Ignition Kit","description":"The Polini digital ignition kit is a precision-engineered internal rotor system designed for track racing on Vespa 50 PK, Special, and 125 Primavera models. By replacing the heavy stock flywheel with a lightweight internal rotor, this kit enables the engine to rev significantly faster and improves power delivery across the entire rpm range. It supports high-revving engines up to 20,000 rpm and includes a stator, rotor, and gearbox support.\n\nThe system features a coil with a digital CDI that utilizes an electronic advance map. To ensure optimal performance for your specific engine build, the kit includes a setup table that facilitates the mechanical adjustment of ignition advance. Note that this ignition system is designed strictly for track racing use and will disable the standard scooter electrical system; the lighting system does not work with this installation.","brand":"Polini","offers":[{"title":"Default Title","offer_id":52663286792504,"sku":"171.0554","price":643.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687525800.webp?v=1784325639","url":"https:\/\/store.motormia.co\/products\/digital-internal-rotor-ignition-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
