Radial master cylinder Ø19mm with integrated oil tank.
The peculiarity of this special master cylinder is the lowered position of the brake fluid tank made to improve the handlebar look and to protect the tank in the event of a fall. You can notice that the Lever-pump-tank assembly is really compact. The support that secures the master cylinder to the handlebar has been raised with respect to the typical position. The master cylinder is now at a lower position (25mm) from the axis of the handlebar; this means there’s the need of a suitable lever that brings the point of force application to the traditional place. The lever consists of two components. The pump-tank body is made of a single solid piece of aluminium, subsequently treated with hard oxidation and rectified. Levers are anodized instead.
The Thunderbreake master cylinder, with its aggressive look, suits the Café Racer models as well as the new generation of HD, so you can choose the version with handlebar 22mm or 1 inch.
