Here the shape is the B005, drawn for the Brembo caliper and measuring 102.2 by 42.0 mm. In EXR the SRK 921 RR gets the compound ZCOO now points endurance and sprint racers toward.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eThe ceramic layer is sintered to the plate rather than pressed against it, which is what keeps the B005 together at the top of its temperature range\u003c\/li\u003e\n\u003cli\u003eNo ECE R90 type approval is documented for this compound - treat the B005 as a track and competition part\u003c\/li\u003e\n\u003cli\u003ePad code ZRM-B005C, 102.2 mm long and 42.0 mm tall - a direct fit in the standard caliper\u003c\/li\u003e\n\u003cli\u003eTested and specified for the 2026 model years of the QJMotor SRK 921 RR, not extrapolated from a neighbouring year\u003c\/li\u003e\n\u003cli\u003eRotor-friendly by formulation: the SRK 921 RR discs see a ceramic film rather than an abrasive\u003c\/li\u003e\n\u003cli\u003eStable friction from the first squeeze to the wear limit, so the SRK 921 RR brakes the same on a cold morning and at the bottom of a pass\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eConstruction and Material Quality\u003c\/h2\u003e\u003cp\u003eTwo things define how a B005 behaves: the ceramic mixture and the plate under it. On the B005 the ceramic material is sintered onto a laser-cut metal plate rather than pressed against it. It is also why ZCOO can quote fade resistance beyond 600 degrees for the B005 without qualifying it.\u003c\/p\u003e\u003ch2\u003ePerformance and Feel\u003c\/h2\u003e\u003cp\u003eEXC Endurance was built for race distance and behaved like it: strong once hot, vague before. EXR keeps the strength and changes the way it arrives, so the force builds with the lever instead of ahead of it. For an SRK 921 RR on track that is the difference between running out of brake and running out of tyre.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eZCOO's 2026 catalogue lists this reference for the QJMotor SRK 921 RR across 1 model year (2026). Before ordering, check that your caliper takes a pad of 102.2 mm length and 42.0 mm height. The same B005 shape covers 117 further machines in the 2026 catalogue. The reference is a front pad; ZCOO lists no rear equivalent.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eNo ECE R90 type approval is documented for this pad. It appears neither in ZCOO's own catalogue nor on the European distributor's site, and no approval number is printed on the packaging data available to us. ZCOO itself describes the compound as suited to competition machines and road machines alike, but that is a description of the mixture, not a type approval. Until the distributor confirms an approval in writing, treat this as a track and competition part: in Germany a replacement brake pad without ECE R90 approval may not be fitted to a motorcycle used on public roads. Ask us before ordering if you need this clarified for your machine.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePart number: Z-B005-EXR (EAN 4950545771773)\u003c\/li\u003e\n\u003cli\u003ePad code: ZRM-B005C\u003c\/li\u003e\n\u003cli\u003eCompound: ZCOO EXR - ceramic-sintered, successor to EXC Endurance\u003c\/li\u003e\n\u003cli\u003ePad dimensions: 102.2 x 42.0 x 8.05 mm (L x H x thickness)\u003c\/li\u003e\n\u003cli\u003eCaliper family: Brembo\u003c\/li\u003e\n\u003cli\u003ePosition: Front axle only\u003c\/li\u003e\n\u003cli\u003eFitment: QJMotor SRK 921 RR, 2026-2026\u003c\/li\u003e\n\u003cli\u003eContents per pack: 1 set = 2 pads for one caliper; a machine with twin front discs needs two packs\u003c\/li\u003e\n\u003cli\u003eRoad approval: No ECE R90 type approval documented - track and competition use\u003c\/li\u003e\n\u003cli\u003eManufacturer: Okada Corporation, Japan\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ZCOO","offers":[{"title":"Default Title","offer_id":53638573293834,"sku":"Z-B005-EXR","price":429.0,"currency_code":"ILS","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/B005-produkt_bfe4ba70-dd92-4146-bee5-c846bdc5668a.png?v=1788779441","url":"https:\/\/inter-pace.com\/en-il\/products\/zcoo-exr-front-brake-pads-qjmotor-srk-921-rr","provider":"Inter-Pace","version":"1.0","type":"link"}
