Exceptional Build Quality
Every HEL radial brake master cylinder is manufactured in-house using solid billets of 6082-T6 aluminum, ensuring outstanding strength and durability. With over an hour of meticulous machining for each body, the cylinder’s bore is precisely measured during production to meet exacting standards. The result is a product that guarantees long-lasting, high-performance braking.
Revolutionary Adjustable Lever Design
The master cylinder features an innovative lever system offering three ratio options in one lever:
18/19, 19/19, and 20/19 ratios – tailored to your riding needs.
Easily adjustable using a pill-shaped insert with two plugs:
Offset hole (near or far): Adjusts to -1 or +1 ratio.
Central hole: Maintains a 1:1 ratio for balanced braking.
With this flexibility, riders can fine-tune braking performance for precision, power, and comfort on demand.
