The 18 mm pivot distance is rated for track use and also recommended for street riding, giving a lever feel that works for both without favouring either. Fitted with a fixed lever, long version, with relieving eyelet, it suits single-disc machines ridden on the road with the occasional trackday.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e15 mm piston diameter, suggested by Accossato for naked and motard bikes\u003c\/li\u003e\n\u003cli\u003e18 mm pivot distance, rated for track use and also recommended for street riding\u003c\/li\u003e\n\u003cli\u003eFixed lever, long version, fitted with a relieving eyelet (RST)\u003c\/li\u003e\n\u003cli\u003eCNC-machined aluminium body with a natural anodised finish\u003c\/li\u003e\n\u003cli\u003eOffset riser that reduces master cylinder deflection during braking\u003c\/li\u003e\n\u003cli\u003ePassive lever stroke cut by more than 50 percent versus a standard radial unit\u003c\/li\u003e\n\u003cli\u003eStainless steel mounting screws and a galvanised steel 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\u003eAccossato machines this master cylinder from a solid aluminium billet in Italy, finishing it with a natural anodised surface. The mounting screws are stainless steel, the bleed valve is galvanised steel, and the internal seals are made from Formula 1 compound to resist heat and sustained brake fluid contact. A built-in offset riser reduces flex of the clamp when the brake is applied hard, and the passive stroke before the pads engage the disc is cut by more than half compared with a standard radial master cylinder.\u003c\/p\u003e\n\u003ch2\u003eA 15 mm Piston Built for Naked and Motard Riding\u003c\/h2\u003e\n\u003cp\u003eBetween the 14 mm piston Accossato suggests for scooters and the 16 mm size rated for single-disc sportbikes, the 15 mm piston used here is aimed specifically at naked and motard machines, where brake systems are typically more capable than a scooter's but lighter than a full sportbike's. The 18 mm pivot distance adds a setting Accossato recommends for both track and street use, so the fixed-lever version here suits an owner who wants one consistent, no-play lever feel whether commuting or doing the odd lapping day.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cp\u003eAccossato does not publish a named vehicle list for this reference, offering it instead as a direct upgrade for naked and motard machines that already run a single-disc radial system in this general size class, from small street-naked models to supermoto-style conversions. Rather than browsing for a matching model, the deciding factors are the handlebar clamp, which should measure 22 mm, and the existing calliper and disc, which need to suit a 15 mm piston; a specialist workshop can confirm compatibility from those two figures alone if there is any doubt.\u003c\/p\u003e\n\u003ch2\u003eRoad Approval\u003c\/h2\u003e\n\u003cp\u003eThis master cylinder has no ABE documented; it is intended for track and competition use.\u003c\/p\u003e\n\u003ch2\u003eScope of Delivery\u003c\/h2\u003e\n\u003cp\u003eThe box contains the Accossato radial brake master cylinder itself, assembled and ready to fit, together with its mounting hardware. A brake light switch is not included and can be ordered separately under part number ID001 or ID002. A fluid reservoir is likewise not included and is sold separately in several styles to suit different handlebar layouts.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePart number: CY067\u003c\/li\u003e\n\u003cli\u003eType: Radial brake master cylinder\u003c\/li\u003e\n\u003cli\u003ePiston diameter: 15 mm\u003c\/li\u003e\n\u003cli\u003ePivot distance: 18 mm\u003c\/li\u003e\n\u003cli\u003eLever: Fixed, long, with relieving eyelet (RST)\u003c\/li\u003e\n\u003cli\u003eBody: CNC-machined aluminium, natural anodised\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: Not included\u003c\/li\u003e\n\u003cli\u003eRoad approval: No ABE documented\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Accossato","offers":[{"title":"Long","offer_id":53850063667466,"sku":"CY067-L-18-RST","price":245.66,"currency_code":"EUR","in_stock":true},{"title":"Short","offer_id":53850490208522,"sku":"CY067-C-18-NRST","price":245.66,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/CY067-2.png?v=1791009779","url":"https:\/\/inter-pace.com\/products\/accossato-radial-brake-master-cylinder-15x18-with-fixed-lever-cy067","provider":"Inter-Pace","version":"1.0","type":"link"}
