It is aimed at riders who want the widest possible range of adjustment from a single unit, without having to choose between the PRS pivot system and the Revolution Lever design used elsewhere in the range.\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\u003eAdjustable lever pivot distance: 17, 18 or 19 mm, suitable for all uses\u003c\/li\u003e\n\u003cli\u003eRevolution Lever, also adjustable by adding or removing inserts, in seven colours\u003c\/li\u003e\n\u003cli\u003eCNC-machined aluminium body with natural anodising\u003c\/li\u003e\n\u003cli\u003eOffset riser that limits master cylinder flex under hard braking\u003c\/li\u003e\n\u003cli\u003ePassive lever stroke cut by more than 50 percent compared with a standard radial master cylinder\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\u003eThis unit is CNC machined from aluminium billet in Italy and carries the same natural anodised finish as the rest of Accossato's flagship brake range. The screws are stainless steel, the bleed valve is zinc-plated steel, and the seals are made from Formula 1 compound to resist the heat cycles and fluid contact a front brake system sees over its working life. An offset riser in the mounting clamp reduces bending of the body under hard braking, and the fluid path is shaped to cut the passive stroke, the travel before the pads actually bite, by more than half compared with a standard radial master cylinder.\u003c\/p\u003e\n\u003ch2\u003eTwo Ways to Adjust the Same Unit\u003c\/h2\u003e\n\u003cp\u003eMost Accossato radial master cylinders offer either a sliding PRS pivot or the insert-based Revolution Lever, but this version carries both. The 17, 18 and 19 mm pivot positions change the mechanical relationship between lever travel and piston movement, lightening or firming up the action in broad steps, while the inserts inside the Revolution Lever allow a finer adjustment on top of whichever pivot position is chosen. Accossato describes the full pivot range as suitable for all uses, so the combination gives a rider moving between the road and the track a wide window to find a brake feel that suits both without a different master cylinder for each.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cp\u003eIn our fitment data, 65 motorcycles across Aprilia, BMW, Ducati, Honda, Kawasaki and Suzuki are confirmed for this master cylinder, among them the Aprilia Tuono V4 1100 Factory (2015-2020), BMW HP4 (2012-2014), Ducati Streetfighter V4 (2020-2023), Kawasaki Z1000SX (2011-2019) and Suzuki GSX-S1000GT (2022-2023).
