The magic of the right tube diameter, right length then their RS-12 was called in to do the work that it was designed to do...perform! Adding power and torque everywhere across the spectrum of the new YZ450 wasn't easy but it was accomplished. Max HP is increased by 8% and max torque is bumped an incredible 13%!\u003c\/p\u003e\n\u003cp\u003eThe new RS-12 system unlocked some key power in the right places. The lower and mid RPM range is really enhanced while not disrupting the handling characteristics on the new YZ chassis. Riding with this new added power really made testing the new system a fun project.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRS-12 Features and benefits:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAggressive intelligently designed, the RS-12 asymmetrical shaped muffler allows maximise capacity and incorporates a resonance chamber for managing sound and increasing usable power.

Machined joints provide a superior and exacting fit for joints by better securing the seal between two surfaces with a perfect 360 degree contact surface which translates into improved system life, fit and performance.\u003c\/li\u003e\n\u003cli\u003eNew patent pending Precision Taper Fit (PTF) insert ring makes it easy to install and remove sound inserts and spark arresters.\u003c\/li\u003e\n\u003cli\u003eWorks-look matte carbon fibre end cap with industry leading design, innovation and detailing as expected from Yoshimura.\u003c\/li\u003e\n\u003cli\u003eCarbon end cap covers the RS-12 inner cap, thus improving looks, while providing easier service as compared to other sandwich mounting designs most commonly found in the industry.\u003c\/li\u003e\n\u003cli\u003eProudly designed, developed and made in the USA!\u003c\/li\u003e\n\u003cli\u003eRepack Kits, optional Inserts and Spark Arresters are available for all models\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/LkWSdyrUhRM?si=E5GNfQmGbhokmTw2\" height=\"215\" width=\"460\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch5\u003eADDITIONAL INFORMATION\u003c\/h5\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/docs.yoshimura-rd.com\/234840S320.pdf\" rel=\"noopener\" target=\"_blank\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong\u003eVIEW INSTALLATION INSTRUCTIONS\u003c\/strong\u003e\u003c\/span\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003e\u003cstrong\u003eBIKE FITMENT\u003c\/strong\u003e\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eYAMAHA\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWR450F 2024-2025\u003c\/li\u003e\n\u003cli\u003eYZ450F 2023-2025\u003c\/li\u003e\n\u003cli\u003eYZ450FX 2024-2025\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"YOSHIMURA","offers":[{"title":"Default Title","offer_id":49447289422108,"sku":"234840S320","price":2099.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0702\/7707\/1132\/files\/1_2748942b-1c45-4743-bd23-864193fe1652.png?v=1721358323","url":"https:\/\/www.motohouse.com.au\/products\/yoshimura-yamaha-yz450f-23-25-yz450fx-wr450f-24-25-rs-12-stainless-full-system","provider":"Moto House","version":"1.0","type":"link"}
