The lever folds in against the bar for easier transport or storage, while the reservoir, adjusting knob and oil level marker remain colour-matched as on the rest of the integrated-reservoir brake 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\u003eFixed 19 mm lever pivot distance, for mixed track and street use\u003c\/li\u003e\n\u003cli\u003eFolding lever, long version, with relieving eyelet (RST), seven colours available\u003c\/li\u003e\n\u003cli\u003eIntegrated fluid reservoir with a colour-matched cover, adjusting knob and oil level marker\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\u003eConstruction is unchanged from the fixed-lever PK039: a forged aluminium body with a CNC-worked cover and lever, stainless steel screws, a zinc-plated bleed valve and seals made from Formula 1 compound. The folding joint in the lever is the only mechanical difference between the two, letting this version tuck flat against the bar when the bike is transported, stored tightly, or dropped at low speed. The offset riser and the shortened passive lever stroke carry over unchanged from the rest of the 19 mm family.\u003c\/p\u003e\n\u003ch2\u003eFolding Convenience at a Mixed-Use Pivot Setting\u003c\/h2\u003e\n\u003cp\u003eRiders who want the balanced, mixed track-and-street lever feel of the 19 mm pivot distance but also value being able to fold the lever away, for a bike kept in a smaller garage, loaded onto a trailer, or ridden two-up with luggage near the bars, get that combination here rather than having to choose the fixed-lever PK039 instead. Nothing about how the brake responds changes with the folding joint; the 19 mm piston and the pivot geometry that Accossato positions between the firmer 20 mm and the softer 18 mm settings are identical between the two part numbers.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cp\u003eOur fitment data confirms the same 65 motorcycles for this part number as for the fixed-lever PK039, including the Aprilia RSV4 RR (2015-2019), BMW K1600 GT (2011-2023), Kawasaki ZX-10 RR (2016-2023) and Suzuki GSX-R 1000 (2003-2023).
