Compared to the Yasuni Carrera 20, the C21 has a slightly longer expansion chamber, delivering strong torque and excellent performance in the mid to high RPM range—ideal for powerful acceleration, especially when exiting corners.Designed for high-revving engines up to 14,000 rpm, the C21 is a top choice for track use, offering rapid acceleration on corners and short straights.All parts required for installation are included.Specifications Yasuni C21 racing cylinderSegment-welded racing cylinderSilencer: blackBracket includedFor horizontal Minarelli (Yamaha Aerox, Malaguti F12 and many more)Without road approval Questions about the product Downloads and Media Data sheetInstallation guide\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBrand: Yasuni\u003c\/li\u003e\n\u003cli\u003eSKU: YAS910B\u003c\/li\u003e\n\u003cli\u003eAvailability: In stock\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Yasuni","offers":[{"title":"Default Title","offer_id":53461511536983,"sku":"YAS910B","price":510.3,"currency_code":"PLN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1012\/4027\/5287\/files\/696365_6341429.jpg?v=1777841577","url":"https:\/\/mattmoto.pl\/en\/products\/exhaust-yasuni-c21-minarelli-horizontal-black-yas910b","provider":"MattMoto Skutery","version":"1.0","type":"link"}
