KustomTech Classic Line 12mm Brake Master Cylinder — Satin Finish
The satin finish is the choice for those who want a discreet yet refined look. No bling, no blinding reflections in the sun—just forged aluminum with a smooth, matte surface that says, "I know what I'm doing." The KustomTech Classic Line TUV 12mm satin brake master cylinder is the ideal KustomTech satin brake master cylinder for a stylish custom build without being over the top.
Made in Italy, designed for riders
Each KustomTech master cylinder is machined from forged aluminum in the brand's Italian workshops. The result? A dense, robust component with a finned cover inspired by the 50s and 60s and a perfectly curved lever . The satin finish is achieved through micro-bead blasting, giving it a unique texture that is both smooth to the touch and anti-reflective.
Technical characteristics
With a 12mm (15/32″) piston , this model offers progressive and controlled braking, perfect for bobbers, choppers, and café racers equipped with a single front disc brake. It mounts to all 1-inch (25,4 mm) handlebars — drag bars, Z-bars, ape hangers, beach bars, whatever your style.
And most importantly: TUV approved . It's not just a showpiece—it's certified road-legal equipment . You can ride with peace of mind, even when facing inspections.
Satin finish KustomTech brake master cylinder: a choice with character
Unlike a mirror polish that draws the eye, a satin finish offers a more subtle look. It better hides everyday micro-scratches and requires less maintenance than a polished finish. It also pairs best with brushed aluminum parts or original engine casings. If you install a satin-finish KustomTech Classic Line clutch lever opposite it, the whole assembly will be perfectly harmonious.

FAQ — Brake Master Cylinders
Hydraulic or cable-driven?
Hydraulic brakes offer modern, progressive braking with precise modulation. Cable (mechanical) brakes require more effort but give the pure vintage look of old-school choppers.
Approved for road use in France?
Yes. All KustomTech master cylinders are approved for European road use (ECE standard) and are compatible with motorcycle insurance. You can install them legally.
Does the system need to be bled?
Yes, absolutely after installation. Use DOT 4 or DOT 5.1 fluid depending on your motorcycle. Allow 30 minutes for a proper bleeding process.
