DescriptionThe whole story▼

The Accossato Ready To Brake clutch master cylinder 16x16 brings the shark-bodied, micro-switch-equipped design across to the clutch side of the range, giving a 16 mm piston its softest pivot setting for the lightest lever pull Accossato offers at this bore size. The folding lever is supplied in seven colours, and a mirror bracket plus an oil tank can be added through the purchase options. It is listed against 51 motorcycles in our fitment data, mostly BMW adventure and roadster models alongside Honda, Kawasaki and Suzuki machines.

Key Features

  • 16 mm piston diameter for the clutch side of the Ready To Brake range
  • 16 mm lever pivot distance, the softest setting, for a lighter clutch pull
  • Folding lever, long version, with relieving eyelet (RST), available in seven colours
  • Shark-shaped body shared with the brake side of the Ready To Brake range
  • Mirror bracket and oil tank selectable through the purchase options
  • Offset fixing riser with a quick-release jumper for faster servicing
  • Stainless steel mounting screws and a zinc-plated bleed valve
  • Seals manufactured from Formula 1 compound material

Construction and Material Quality

This clutch master cylinder is produced in Italy, machined from an aluminium block on CNC equipment and built to the same hardware specification as the brake-side Ready To Brake units: stainless steel screws, a zinc-plated bleed valve and seals made from Formula 1 compound, which keep working through the heat and fluid exposure that come with daily clutch use. A quick-release jumper sits in the offset fixing riser, letting the pump be taken off its mounting for servicing without opening the hose joint, and that same offset keeps the body from flexing while the gearbox is worked hard.

The Softest Setting on the Clutch Side

Carrying the Ready To Brake shark design over to a clutch pump changes what the integrated switch inside does: rather than operating the brake light, it is there purely for the micro-switch function the body was designed around, while clutch actuation itself runs through the 16 mm piston and the pivot distance. At 16 mm, the pivot used here is the softest setting Accossato offers on this bore, giving a noticeably lighter lever pull than the 18 mm version in exchange for a slightly longer stroke before the clutch plates separate, a trade most riders accept for an easier pull in stop-and-go traffic.

Fitment and Compatibility

Our records match 51 motorcycles to this clutch master cylinder, the majority of them BMW, Honda, Kawasaki and Suzuki models such as the BMW F800GS (2008-2016), Honda CB1100 (2017-2017), Kawasaki ER-6N (2012-2016), Suzuki DL1000 V-Strom (2014-2019) and Suzuki SV650 (2016-2020). The Fitment tab on this page holds the complete list with exact model years for checking against your own registration before you buy.

Road Approval

This clutch 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 Ready To Brake 16x16 radial clutch master cylinder fitted with a long folding lever and relieving eyelet (RST) in the colour selected, plus the matching mounting nut. Stainless steel mounting screws, the zinc-plated bleed valve and the Formula 1 compound seals are assembled on the unit. The mirror bracket and oil tank are selectable through the purchase options and are not included as standard; the fluid reservoir otherwise must be purchased separately.
