The 19 mm piston is matched to a fixed 18 mm lever pivot distance that Accossato rates for track use and also recommends for street riding, while the long folding lever with relieving eyelet is available in seven colours to match the rest of the bike. This version is confirmed against the Ducati Desert X and the Ducati Scrambler Icon in our fitment data.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e19 mm piston diameter, suitable for dual-disc braking systems\u003c\/li\u003e\n\u003cli\u003eFixed 18 mm lever pivot distance, for track use and also recommended for street use\u003c\/li\u003e\n\u003cli\u003eIntegrated fluid reservoir with a colour-matched cover, adjusting knob and oil level marker\u003c\/li\u003e\n\u003cli\u003eFolding lever, long version, with relieving eyelet (RST), seven colours available\u003c\/li\u003e\n\u003cli\u003eForged aluminium body with a CNC-worked cover and lever\u003c\/li\u003e\n\u003cli\u003eOffset riser that reduces bending of the master cylinder while braking\u003c\/li\u003e\n\u003cli\u003eStainless steel mounting screws and a zinc-plated bleed valve\u003c\/li\u003e\n\u003cli\u003eSeals manufactured from Formula 1 compound material\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eConstruction and Material Quality\u003c\/h2\u003e\n\u003cp\u003eThe body of this master cylinder is forged aluminium, while the cover and the lever itself are CNC worked, a combination Accossato uses on the integrated-reservoir versions of the radial brake range to keep the reservoir, knob and cover all finished in the same colour as the lever. The mounting hardware follows the same specification as the rest of the lineup: stainless steel screws, a zinc-plated bleed valve and seals made from Formula 1 compound. An offset riser limits how much the unit flexes under hard braking, and the internal geometry is shaped so that pulling the lever cuts the passive stroke, the gap before the pads actually bite, by more than half compared with a conventional radial master cylinder.\u003c\/p\u003e\n\u003ch2\u003eWhy This Version Has Only Two Confirmed Fitments\u003c\/h2\u003e\n\u003cp\u003eThe piston and pivot combination on this master cylinder, 19 mm matched to a fixed 18 mm distance, is shared across several Accossato part numbers, but the mounting geometry and hose routing that let a given code bolt straight onto a specific motorcycle without extra brackets are not identical across every model it could technically clamp onto. For the PK021, Accossato confirms a direct fit on the Ducati Desert X and the Ducati Scrambler Icon; riders on other 19 mm dual-disc machines with a 22 mm handlebar clamp may still find the unit compatible but should check their own setup rather than assume it from the piston size alone.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cp\u003eThis master cylinder is listed against 2 motorcycles in our fitment data: the Ducati Desert X (2022-2024) and the Ducati Scrambler Icon (2015-2024).

Stainless steel mounting screws, the zinc-plated bleed valve and the Formula 1 compound seals are assembled on the unit. The brake light switch, available separately as ID001 or ID002, and the mirror holder, available separately as MH007 or MH008, are not included.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePart number: PK021\u003c\/li\u003e\n\u003cli\u003eType: Radial brake master cylinder\u003c\/li\u003e\n\u003cli\u003ePiston diameter: 19 mm\u003c\/li\u003e\n\u003cli\u003ePivot distance: 18 mm\u003c\/li\u003e\n\u003cli\u003eLever: Folding, long, with relieving eyelet (RST), 7 colours\u003c\/li\u003e\n\u003cli\u003eBody: Forged aluminium, CNC-worked cover and lever\u003c\/li\u003e\n\u003cli\u003eHose thread: M10x1\u003c\/li\u003e\n\u003cli\u003eBrake light switch: Not included (ID001 or ID002 separately)\u003c\/li\u003e\n\u003cli\u003eReservoir: Integrated, colour-matched to lever, with oil level marker\u003c\/li\u003e\n\u003cli\u003eRoad approval: No German approval documented\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Accossato","offers":[{"title":"Black \/ Long","offer_id":53850078806282,"sku":"PK021N-L-18-RST","price":342.18,"currency_code":"EUR","in_stock":true},{"title":"Blue \/ Long","offer_id":53850078839050,"sku":"PK021B-L-18-RST","price":342.18,"currency_code":"EUR","in_stock":true},{"title":"Gold \/ Long","offer_id":53850078871818,"sku":"PK021Y-L-18-RST","price":342.18,"currency_code":"EUR","in_stock":true},{"title":"Green \/ Long","offer_id":53850078904586,"sku":"PK021G-L-18-RST","price":342.18,"currency_code":"EUR","in_stock":true},{"title":"Orange \/ Long","offer_id":53850078937354,"sku":"PK021O-L-18-RST","price":342.18,"currency_code":"EUR","in_stock":true},{"title":"Red \/ Long","offer_id":53850078970122,"sku":"PK021R-L-18-RST","price":342.18,"currency_code":"EUR","in_stock":true},{"title":"Silver \/ Long","offer_id":53850079002890,"sku":"PK021S-L-18-RST","price":342.18,"currency_code":"EUR","in_stock":true},{"title":"Black \/ Short","offer_id":53850568130826,"sku":"PK021N-C-18-NRST","price":342.18,"currency_code":"EUR","in_stock":true},{"title":"Blue \/ Short","offer_id":53850568163594,"sku":"PK021B-C-18-NRST","price":342.18,"currency_code":"EUR","in_stock":true},{"title":"Gold \/ Short","offer_id":53850568196362,"sku":"PK021Y-C-18-NRST","price":342.18,"currency_code":"EUR","in_stock":true},{"title":"Green \/ Short","offer_id":53850568229130,"sku":"PK021G-C-18-NRST","price":342.18,"currency_code":"EUR","in_stock":true},{"title":"Orange \/ Short","offer_id":53850568261898,"sku":"PK021O-C-18-NRST","price":342.18,"currency_code":"EUR","in_stock":true},{"title":"Red \/ Short","offer_id":53850568294666,"sku":"PK021R-C-18-NRST","price":342.18,"currency_code":"EUR","in_stock":true},{"title":"Silver \/ Short","offer_id":53850568327434,"sku":"PK021S-C-18-NRST","price":342.18,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/PK021-1.png?v=1791010370","url":"https:\/\/inter-pace.com\/products\/accossato-radial-brake-master-cylinder-19x18-with-integrated-reservoir-and-folding-lever-pk021","provider":"Inter-Pace","version":"1.0","type":"link"}
