Thumb Brake Master Cylinder Kit by Accossato Racing

Accossato has been producing Italian made parts since 1969. Accossato braking components can be found in every racing paddock around the world. From Motoamerica to MotoGP, Accossato produces some of the best braking components in the world.

This thumb brake master cylinder allows you to operate your rear brake, with your thumb (typically mounted on the clutch side). This is a common upgrade for track riders and race teams.

This Accossato Thumb Rear Brake Master Cylinder is in CNC machined aluminum. The mounting bracket (as shown) is included. Brake line fitment is standard 8mm diameter.

Note: Accossato does not recommend mounting this thumb brake, in conjunction with the stock rear (foot controlled) master cylinder.  Accossato recommends mounting this thumb brake in conjunction with the double-ended rear brake master cylinder (code MP005) if you want to retain the brake function of your standard foot pedal rear brake in addition to this thumb brake.

Note: Brake lines and fluid reservoir are not included with this kit, as some applications may reuse the stock components.

Note: Designed to mount to standard 22mm handlebars or clipons.
