Description

Rear brake master cylinder repair kit to fit 1/2” bore. Before buying look on the back of the master cylinder where the size, either 14 mm or 1/2” will be cast in. Replaces Triumph T2022110.

Fits : America EFI, Bobber, Rocket III, Speedmaster EFI, Thunderbird 1700, Tiger Sport 660, Tiger 800, Tiger 850 Sport, Tiger 900,  Tiger 1200, Trident 660.
If the size marked is 14 mm, use product B010.

A larger bore on the master cylinder will increase your pedal effort required and decrease your pedal travel. Unless there is an issue with pedal distance/travel, it comes down to rider preference.
