On a Ducati Monster 821 set up for circuit work, a light trailing pedal into a slow corner settles the machine and shortens the distance the front has to deal with, and it does that lap after lap for the length of a session. Accossato's ZXC ceramic racing material is available for that duty on the AGPA42 rear pad as article AGPA42ZXC, listed for the Monster 821 from 2014 to 2021.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eRear brake pads for the Ducati Monster 821, 2014 to 2021\u003c\/li\u003e\n\u003cli\u003eAGPA42ZXC: the AGPA42 shape in the ZXC ceramic racing material\u003c\/li\u003e\n\u003cli\u003eAccossato describes a ceramic compound meant for racing\u003c\/li\u003e\n\u003cli\u003eFor riders who use the rear pedal deliberately on circuit\u003c\/li\u003e\n\u003cli\u003eThe rear runs a single caliper, so one box does the axle\u003c\/li\u003e\n\u003cli\u003eTwo pads per box, the set for that caliper\u003c\/li\u003e\n\u003cli\u003eOR and ST cover the same shape in other materials\u003c\/li\u003e\n\u003cli\u003eNo German ABE in our files; racing part\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eConstruction and Material Quality\u003c\/h2\u003e\n\u003cp\u003eAccossato assigns this material to racing and identifies it as ceramic, and that is the whole of the manufacturer's statement. For a rear pad the practical consequence is about feel more than outright stopping power, since almost nobody hauls a bike down on the back wheel alone. The AGPA42 plate carrying the compound is the standard item used throughout this family, so a rider trying the ceramic grade after running something else is not adjusting anything, merely reading a different suffix when the box is opened.\u003c\/p\u003e\n\u003ch2\u003eThe Rear Pedal Inside a Timed Session\u003c\/h2\u003e\n\u003cp\u003eRiders who use the rear brake on a circuit tend to use it constantly and gently rather than occasionally and hard. It comes in before the apex of a slow corner, it holds the attitude of the bike while the throttle is picked up, and on a Monster 821 with a fairly upright riding position it is genuinely useful for keeping the machine from standing up under power. All of that is continuous work on a small disc with nowhere to shed heat.\u003c\/p\u003e\n\u003cp\u003eWatch for the consequences. A rear caliper worked this way wears its pads unevenly if the slides are dry, so check both sides after a session rather than assuming they match. Confirm that the pedal returns cleanly and is not being held against the disc by a lazy linkage. Look at the fluid level, clean the pistons before pushing them back at a pad change, and bed a new set in on the out lap of the session that follows.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cp\u003eFor the rear wheel Accossato lists this article across 2014 to 2021, the Stealth model of 2019 to 2021 included. One caliper and therefore one box is the whole story at that end. Front pads for the same Monster 821 are the AGPA177 over the same years, with two boxes needed there. The DK008 and the DKS053 appear in the Accossato disc catalogue for this bike. Check the article number when ordering, since pad shapes are shared between models.\u003c\/p\u003e\n\u003ch2\u003eRoad Approval\u003c\/h2\u003e\n\u003cp\u003eDocumentation for the AGPA42ZXC includes no German ABE and no test report, so the pads are supplied purely for racing and closed-course events.\u003c\/p\u003e\n\u003ch2\u003eScope of Delivery\u003c\/h2\u003e\n\u003cp\u003eOne box, two AGPA42 pads in the ZXC ceramic racing material, the complete rear set for the Monster 821.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePart number: AGPA42ZXC\u003c\/li\u003e\n\u003cli\u003eCompound: ZXC ceramic racing\u003c\/li\u003e\n\u003cli\u003eDimensions: 50.9 × 53.9 × 7.3 mm\u003c\/li\u003e\n\u003cli\u003eMaterial: Friction material principally composed of a ceramic compound\u003c\/li\u003e\n\u003cli\u003eFriction coefficient: 0.78 average (0.60 minimum, 0.84 maximum), JASO regulation\u003c\/li\u003e\n\u003cli\u003eDensity: 3.66 g\/cm³ at 20 °C (+0.10 \/ −0.05)\u003c\/li\u003e\n\u003cli\u003eTemperature resistance: 450 °C working, 600 °C maximum\u003c\/li\u003e\n\u003cli\u003eContents: 2 brake pads, one set for one caliper\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Accossato","offers":[{"title":"Default Title","offer_id":53817527927050,"sku":"AGPA42ZXC","price":84.16,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/AGPA42ZXC-Ducati-MONSTER-821-platzhalter.png?v=1790584788","url":"https:\/\/inter-pace.com\/products\/accossato-zxc-ceramic-rear-brake-pads-ducati-monster-821-2014-2021-agpa42zxc","provider":"Inter-Pace","version":"1.0","type":"link"}
