The shorter lever stroke that results suits circuit riders willing to trade a lighter lever action for a more immediate response. The lever is fixed, long and fitted with a relieving eyelet, the body is natural anodised, and the lever is available in a choice of colours.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e17 mm piston diameter, suggested for motorcycles with calliper mounting bolts 32 mm apart or less\u003c\/li\u003e\n\u003cli\u003e20 mm fixed lever pivot distance, the firmest setting in the 17 mm range, not recommended for street use\u003c\/li\u003e\n\u003cli\u003eFixed lever, long version, with a relieving eyelet (RST)\u003c\/li\u003e\n\u003cli\u003eLever supplied in a choice of colours, with a matching adjusting knob\u003c\/li\u003e\n\u003cli\u003eCNC-machined aluminium body with a natural anodised finish\u003c\/li\u003e\n\u003cli\u003eOffset riser that limits master cylinder flex under hard braking\u003c\/li\u003e\n\u003cli\u003ePassive lever stroke reduced by more than 50 percent versus a standard radial master cylinder\u003c\/li\u003e\n\u003cli\u003eStainless steel mounting screws, zinced bleed valve and Formula 1 compound seals\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eConstruction and Material Quality\u003c\/h2\u003e\n\u003cp\u003eMade in Italy from forged aluminium, this master cylinder is CNC machined and finished with a natural anodised surface, in line with the rest of the 17 mm range. Stainless steel screws, a zinced bleed valve and Formula 1 compound seals are specified to handle the heat and wear that come from the hard, repeated braking this firmer pivot setting tends to see on track days. An offset riser in the mounting clamp resists bending under that load, and the bore geometry cuts the passive stroke to less than half the length a standard radial unit would need. The hose connection remains the familiar M10x1 thread.\u003c\/p\u003e\n\u003ch2\u003eTrack-Only Bite from the 17 mm Piston's Firmest Pivot\u003c\/h2\u003e\n\u003cp\u003eThe 20 mm pivot distance is the firmest setting Accossato offers across this piston size, shortening the lever stroke for a given hand movement while asking for more force to reach full braking power, and the manufacturer is explicit that it is not recommended for street use. Combined with the 17 mm piston, suited to calliper mounting bolts 32 mm apart or closer, this gives circuit riders a short, direct lever stroke at the cost of the easier, more forgiving pull that the 18 mm and 19 mm pivot settings provide on the road. It is a deliberate choice for track days rather than an everyday setup.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cp\u003eThis master cylinder, like its folding-lever counterpart, comes with no motorcycle-specific fitment list from Accossato; treat it as a universal 17 mm radial unit for a 22 mm handlebar clamp. Measure your bars, confirm the brake system is designed around a 17 mm bore, and check that the calliper's two mounting bolts sit no more than 32 mm apart before you commit to buying.\u003c\/p\u003e\n\u003ch2\u003eRoad Approval\u003c\/h2\u003e\n\u003cp\u003eThis master cylinder is not supplied with German road-approval documentation; it is intended for track and competition use.\u003c\/p\u003e\n\u003ch2\u003eScope of Delivery\u003c\/h2\u003e\n\u003cp\u003eThe package includes the Accossato 17x20 radial brake master cylinder fitted with the fixed, long lever with relieving eyelet, in the colour selected, together with the matching mounting nut. Stainless steel mounting screws, the zinced bleed valve and the Formula 1 compound seals are assembled on the unit. The stop light switch, available separately as ID001 or ID002, and the fluid reservoir are not included and must be purchased separately.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePart number: CL078\u003c\/li\u003e\n\u003cli\u003eType: Radial brake master cylinder\u003c\/li\u003e\n\u003cli\u003ePiston diameter: 17 mm\u003c\/li\u003e\n\u003cli\u003ePivot distance: 20 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 German approval documented\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Accossato","offers":[{"title":"Black \/ Long","offer_id":53850080936202,"sku":"CL078N-L-20-RST","price":257.8,"currency_code":"EUR","in_stock":true},{"title":"Blue \/ Long","offer_id":53850081165578,"sku":"CL078B-L-20-RST","price":257.8,"currency_code":"EUR","in_stock":true},{"title":"Gold \/ Long","offer_id":53850081198346,"sku":"CL078Y-L-20-RST","price":257.8,"currency_code":"EUR","in_stock":true},{"title":"Green \/ Long","offer_id":53850081231114,"sku":"CL078G-L-20-RST","price":257.8,"currency_code":"EUR","in_stock":true},{"title":"Orange \/ Long","offer_id":53850081263882,"sku":"CL078O-L-20-RST","price":257.8,"currency_code":"EUR","in_stock":true},{"title":"Red \/ Long","offer_id":53850081296650,"sku":"CL078R-L-20-RST","price":257.8,"currency_code":"EUR","in_stock":true},{"title":"Silver \/ Long","offer_id":53850081329418,"sku":"CL078S-L-20-RST","price":257.8,"currency_code":"EUR","in_stock":true},{"title":"Black \/ Short","offer_id":53850478379274,"sku":"CL078N-C-20-RST","price":257.8,"currency_code":"EUR","in_stock":true},{"title":"Blue \/ Short","offer_id":53850478412042,"sku":"CL078B-C-20-RST","price":257.8,"currency_code":"EUR","in_stock":true},{"title":"Gold \/ Short","offer_id":53850478444810,"sku":"CL078Y-C-20-RST","price":257.8,"currency_code":"EUR","in_stock":true},{"title":"Green \/ Short","offer_id":53850478477578,"sku":"CL078G-C-20-RST","price":257.8,"currency_code":"EUR","in_stock":true},{"title":"Orange \/ Short","offer_id":53850478510346,"sku":"CL078O-C-20-RST","price":257.8,"currency_code":"EUR","in_stock":true},{"title":"Red \/ Short","offer_id":53850478543114,"sku":"CL078R-C-20-RST","price":257.8,"currency_code":"EUR","in_stock":true},{"title":"Silver \/ Short","offer_id":53850478575882,"sku":"CL078S-C-20-RST","price":257.8,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/CL078-1.png?v=1791010451","url":"https:\/\/inter-pace.com\/products\/accossato-radial-brake-master-cylinder-17x20-with-fixed-lever-rst-cl078","provider":"Inter-Pace","version":"1.0","type":"link"}
