DescriptionThe whole story▼

This folding-lever version of the 14x20 keeps the same track-only character as its fixed-lever counterpart: a 14 mm piston and a 20 mm pivot distance that Accossato does not recommend for street riding, chosen by riders who want the shortest possible lever stroke on circuit days. The folding lever adds a degree of protection at the paddock or in the pits, hinging back under an impact instead of snapping, while the relieving eyelet, lever colour choice and matching adjusting knob all carry over from the rest of the 14 mm family.

Key Features

  • 14 mm piston diameter, suggested for scooters and smaller motorcycles
  • 20 mm fixed lever pivot distance, the firmest setting in the 14 mm range, not recommended for street use
  • Folding lever, long version, with a relieving eyelet (RST)
  • Lever supplied in a choice of colours, with a matching adjusting knob
  • CNC-machined aluminium body with a natural anodised finish
  • Offset riser that limits master cylinder flex under hard braking
  • Passive lever stroke reduced by more than 50 percent versus a standard radial master cylinder
  • Stainless steel mounting screws, zinced bleed valve and Formula 1 compound seals

Construction and Material Quality

Like every other 14 mm unit in the range, this master cylinder is forged, CNC machined and natural anodised in Italy. Stainless steel screws, a zinced bleed valve and Formula 1 compound seals are built in to withstand sustained heat cycling and continuous brake fluid exposure, both more likely given the firmer 20 mm pivot this unit uses. An offset riser in the clamp cuts down on flex under hard braking, and the internal passages are shaped so the passive stroke runs well under half the length of a conventional radial master cylinder. Hoses connect through the M10x1 thread used throughout the range.

A Folding Lever Paired with the Shortest Stroke

Nothing changes mechanically between this unit and the fixed-lever 14x20: the piston stays at 14 mm, suggested for scooters, and the pivot distance stays at 20 mm, the firmest, shortest-stroke setting in the family and one Accossato reserves for track use rather than the road. What a folding lever brings is resilience when the bike is dropped, tipped over in the paddock, or knocked while being wheeled around, since the lever can swing back on its hinge rather than breaking off outright. For riders who already favour the sharpest pivot setting for circuit work, pairing it with a folding lever is a practical way to reduce the chance of a damaged control between sessions.

Fitment and Compatibility

No vehicle list is published for this master cylinder. As a universal 14 mm radial unit for 22 mm handlebar clamps it suits a wide range of machines rather than a confirmed set, so check your own clamp diameter, your brake system's piston requirement, and the calliper and disc fitted to your bike before you commit to an order.

Road Approval

This master cylinder is not supplied with German road-approval documentation; it is intended for track and competition use.

Scope of Delivery

The package includes the Accossato 14x20 radial brake master cylinder fitted with the folding, 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.
