KustomTech Classic Line 14mm Brake Master Cylinder — Satin Finish
Are you building a project with dual front discs or a heavier bike that requires more hydraulic pressure? The KustomTech Classic Line TUV 14mm satin brake master cylinder is exactly what you need. Same legendary design as the 12mm, but with a larger piston for superior braking power.
14mm: more power, same elegance
The 14mm (9/16″) piston moves more brake fluid with each lever pull. The result: more powerful and direct braking , essential when riding with dual discs or a motorcycle weighing over 300 kg. It's also the choice of riders who prefer sharper, more responsive braking.
Everything else is identical to the 12mm model: Italian forged aluminum , vintage finned cover, smooth-profile lever. The micro-bead blasted satin finish provides a soft and understated texture, perfect for builds that prioritize consistency over flashiness.
TUV approved: drive legally
Like the entire Classic Line range, this master cylinder is TÜV certified . This is a crucial detail, especially considering that many custom parts on the market are not road-legal. With KustomTech, you're investing in a part that's both beautiful and street legal.
KustomTech 14mm satin brake master cylinder: what is the difference with the 12mm?
It's a matter of brake setup . The 12mm is suitable for motorcycles with a single front disc—lightweight choppers, bobbers, and café racers. The 14mm is recommended for dual discs , heavier motorcycles like baggers or custom touring bikes, or if you simply want more responsive braking. If you're unsure, don't hesitate to ask us for advice.

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.

The throttle grip has transformed my handlebars. The return to neutral is smooth yet firm. With its mirror-polished finish, it's almost a shame to ride it because it's so beautiful.
Christophe G. (confirmed customer) –
Received yesterday, installed this morning. The fabric texture is pleasant, the brass is solid, not cheap. Original and comfortable for long journeys.

This is the third KustomTech piece I've assembled, and I still get that feeling of holding an exceptional object. The case spins like butter.
