Larger gears result in a shorter gear ratio, which benefits the scooter's traction, while a longer gear ratio favors top speed. Stock engines usually don't have the power needed to pull a modified gear ratio, so a higher gear ratio is only recommended for tuned engines. Definitely a good choice if you want to maximize the potential of your tuned engine.\u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003e Primary gear: 15\/50\u003c\/li\u003e\n\n\u003cli\u003e Pressure fitting\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"Billaricambi SRLS","offers":[{"title":"Default Title","offer_id":49332540473668,"sku":"CGN263894","price":70.15,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0856\/3730\/0548\/files\/307428_2702475-1.jpg?v=1755869783"},{"product_id":"ingranaggio-primario-stage6-15-38-piaggio-nrg-dopo-il-98","title":"S6-2014012P Primary Gear Stage6, 15\/38 Piaggio NRG after 98","description":"\u003ch2\u003e PRIMARY REPORTS Piaggio since 1998\u003c\/h2\u003e\n\u003cp\u003e \u003cstrong\u003eStage6 primary gear ratio 15\/38 (2.53),\u003c\/strong\u003e \u003cstrong\u003ePiaggio, with\u003c\/strong\u003e counter bearing in transmission cover, including secondary gear, pre-assembled\u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003e For Piaggio after 1998, with counter bearing in the transmission cover\u003c\/li\u003e\n\n\u003cli\u003e Number of teeth: 15\/38 (1:2.53)\u003c\/li\u003e\n\n\u003cli\u003e Only suitable for scooters with 10\" tires (Zip) - not for Typhoon \/ TPH!!!\u003c\/li\u003e\n\n\u003cli\u003e Pre-assembled\u003c\/li\u003e\n\n\n\u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eNote: On vehicles produced after August 1998, the shaft on which the torque converter rests is supported by the transmission cover.
