It is recommended for vehicles already upgraded with a 70cc big bore cylinder kit. A stock 50cc engine does not possess enough low-end horsepower to effectively pull a taller gear set, which will result in sluggish acceleration. Installation requires a 10x1.25mm nut (not included).\u003c\/p\u003e\u003chr\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGear Ratio Count:\u003c\/strong\u003e 13 \/ 44 Tooth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Type Match:\u003c\/strong\u003e Minarelli 50cc 2-Stroke Family\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRequired Fastener Size:\u003c\/strong\u003e 10x1.25mm Nut (Sold Separately)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number (MPN):\u003c\/strong\u003e 202.1370\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVendor:\u003c\/strong\u003e Polini Motori\u003c\/li\u003e\n\u003c\/ul\u003e\u003chr\u003e\u003cp\u003e\u003ca href=\"https:\/\/www.P65Warnings.ca.gov\" target=\"_blank\"\u003eCalifornia Prop 65 Warning: www.P65Warnings.ca.gov\u003c\/a\u003e\u003c\/p\u003e","brand":"Polini","offers":[{"title":"Default Title","offer_id":48112108044475,"sku":"1200-1232","price":102.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0719\/1340\/6651\/files\/1200-1232_80fc4f0d-a623-40cb-9189-ec5bcfcd7ed0.jpg?v=1784301650","url":"https:\/\/thriftyscooters.com\/products\/polini-up-gear-set-13x44-yamaha-zuma-1200-1232","provider":"Thrifty Scooters","version":"1.0","type":"link"}
