A higher ratio (shorter transmission) will make the engine reach maximum horsepower more quickly, meaning acceleration will be improved, sacrificing a bit of top speed. A lower gear ratio (longer transmission) has the opposite effect - higher top speed and slower acceleration.This is the Polini Primary Transmission 15\/38 (gear ratio = 2.53) Vespa ET2 98 \/ LX \/ LXV \/ S 50cc with straight teeth for reducing friction and heat.15\/38 -\u0026gt; gear ratio: 2.53 = +22.9% Questions about the product\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBrand: Polini\u003c\/li\u003e\n\u003cli\u003eSKU: P202.1405\u003c\/li\u003e\n\u003cli\u003eAvailability: In stock\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eNotes and Safety Scooter gearboxThe transmission of scooters and some mopeds is located in a case behind the clutch and torque driver and has the function of reducing rpm and ultimately driving the wheel axle.The transmission of a scooter has a direct influence on top speed. If the engine develops enough power and torque at low rpm, you can choose a longer gear ratio to achieve a higher top speed without any noticeable loss in acceleration.Please note: if you don't have a press, better choose pre-assembled gears!\u003c\/p\u003e","brand":"Polini","offers":[{"title":"Default Title","offer_id":53460640891223,"sku":"P202.1405","price":133.88,"currency_code":"PLN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1012\/4027\/5287\/files\/303270_2950086.jpg?v=1777829795","url":"https:\/\/mattmoto.pl\/en\/products\/primary-gears-polini-15-38-2-53-22-9-vespa-et2-98-lx-50cc-p202-1405","provider":"MattMoto Skutery","version":"1.0","type":"link"}
