This listing carries a black anodised finish, and the eight pistons inside run in two diameters, 25 mm and 30 mm, rather than a single uniform size. A dust seal is included, and four AGPA290 pads per caliper are needed, bought separately. Buell and EBR owners replacing a caliper that has worn out or seized after years of service typically start from the black anodised version, since it is closest to the look of most factory-fitted calipers on these models.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e8-piston CNC radial brake caliper, 86.3 mm mounting centres\u003c\/li\u003e\n\u003cli\u003ePistons in two diameters, 25 mm and 30 mm\u003c\/li\u003e\n\u003cli\u003eDust seal included\u003c\/li\u003e\n\u003cli\u003eFour brake pads per caliper, code AGPA290, not included\u003c\/li\u003e\n\u003cli\u003eBlack anodised finish\u003c\/li\u003e\n\u003cli\u003eBuilt for Buell motorcycles (2003-2010) and EBR models\u003c\/li\u003e\n\u003cli\u003eFour applications listed in the fitment tab\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eConstruction and Material Quality\u003c\/h2\u003e\u003cp\u003eEight pistons set the PZ021 apart from the rest of Accossato's radial range, which mostly runs two or four pistons per caliper. Splitting the eight across two diameters, 25 mm and 30 mm, lets Accossato vary the clamping force across the pad surface rather than applying it evenly from a single piston size. A dust seal protects the additional piston bores, and the black anodised finish on this listing is one of three colour options applied to the same CNC-machined body.\u003c\/p\u003e\u003ch2\u003eWhy This Caliper Needs Eight Pistons\u003c\/h2\u003e\u003cp\u003eA caliper built for Buell and EBR applications needs to clamp a disc with enough force across a wider pad area than a smaller radial caliper manages with two or four pistons, which is the reasoning behind the PZ021's eight-piston layout. The two piston diameters, 25 mm and 30 mm, let the caliper apply graduated pressure rather than a single uniform force across the whole pad, and four pads per caliper under code AGPA290 spread that contact area further still. None of this changes how the caliper mounts: the 86.3 mm centre distance stays fixed whichever of the three finishes is chosen.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis caliper is matched to Buell motorcycles from 2003 to 2010 and to EBR models rather than sold as a universal radial unit. Our fitment tab records four applications for the PZ021: the Buell EBR 1190 RX and SX and the Hammerhead 1190 and 1190 SX, none of which currently appear in our own garage listing. Before ordering, confirm the 86.3 mm mounting centres and the disc thickness already fitted, and have the caliper installed by a qualified workshop.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eAccossato does not document ABE for the PZ021 in Germany, so fitting this caliper to a road-registered Buell or EBR model is subject to registration with the relevant authority before the bike returns to the road; a testing authority can confirm what documentation is needed. Because the brake system is safety-relevant, fitting and bleeding should be carried out by a qualified workshop rather than at home.\u003c\/p\u003e\u003ch2\u003eScope of Delivery\u003c\/h2\u003e\u003cp\u003e1x Accossato PZ021 8-piston radial brake caliper in black anodised finish, with dust seal fitted; brake pads (code AGPA290) sold separately.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePart number: PZ021\u003c\/li\u003e\n\u003cli\u003eType: CNC 8-piston radial brake caliper\u003c\/li\u003e\n\u003cli\u003eMounting centres: 86.3 mm\u003c\/li\u003e\n\u003cli\u003ePistons: 8, 25\/30 mm\u003c\/li\u003e\n\u003cli\u003eDust seal: Yes\u003c\/li\u003e\n\u003cli\u003ePads: AGPA290, not included\u003c\/li\u003e\n\u003cli\u003eFinish: Black anodised\u003c\/li\u003e\n\u003cli\u003eFitment: 4 applications, see Fitment tab\u003c\/li\u003e\n\u003cli\u003eRoad approval: No ABE documented\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Accossato","offers":[{"title":"Default Title","offer_id":53905113350410,"sku":"PZ021N","price":869.54,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/PZ021-BLACK-ANODISED_1.png?v=1791897777","url":"https:\/\/inter-pace.com\/products\/accossato-8-piston-radial-brake-caliper-cnc-86-3-mm-for-buell-and-ebr-black-anodised-pz021","provider":"Inter-Pace","version":"1.0","type":"link"}
