DescriptionThe whole story▼
When lap times are decided under late braking and every millimetre of lever travel counts, the Talos XS.16 radial master cylinder gives you the weapon-grade precision your braking system deserves. CNC-machined from solid billet aluminium, with a 16 mm piston and a click-adjustable lever ratio spanning 18 to 20 mm, this is a master cylinder built to the exacting demands of circuit racing — and a transformative upgrade for any high-performance street or track build.
Key Features
- CNC-milled billet aluminium housing, black anodised, delivers maximum rigidity and a consistent brake feel under repeated hard stops
- 16 mm piston diameter optimised for large four-piston caliper systems and high-performance braking setups
- Click-adjustable lever ratio between 18 mm and 20 mm lets you dial in the exact feel for your tyre, circuit and riding style
- Folding brake lever reduces the risk of lever breakage in a get-off or low-speed tip-over — a genuine race-proven detail
- Titanium bleed valve and stainless steel clamp and pivot bolts throughout for corrosion resistance and long-term reliability
- Hard-anodised aluminium piston and integrated brake light switch complete a fully race-ready specification
- Total weight of only 312 g keeps unsprung and handlebar mass to an absolute minimum
Billet Construction and Material Specification
The XS.16 housing is machined from a single block of high-grade aluminium billet — no casting porosity, no weak spots. The resulting part combines extreme stiffness with a weight of just 312 g, ensuring that the pressure point stays utterly consistent whether you are braking from 200 km/h on the main straight or scrubbing speed deep into a tight hairpin. Every material choice reflects a deliberate performance hierarchy: hard-anodised aluminium piston for wear resistance, a titanium bleeder for minimum weight at the caliper end, and stainless steel hardware everywhere structural integrity matters.
16 mm Piston — Built for Four-Piston Calipers and Racing Systems
The 16 mm bore is the sweet spot for large four-piston monoblock calipers found on modern supersports and superbike-class machines. It produces strong, clean pressure build-up with immediate feedback through the lever — no vagueness, no dead travel. Whether you are running Brembo, Nissin or any comparable OEM caliper, the XS.16 piston diameter is sized to generate the hydraulic force these systems demand without over-serving or under-serving the circuit.
Adjustable Lever Ratio — 18 to 20 mm Fine-Tuning
The click-adjustable ratio system is one of the XS.16's defining race advantages. Moving to the 18 mm setting sharpens initial bite and tightens the pressure point for riders who prefer an aggressive, front-loaded braking style. Switching to 20 mm softens the lever progression slightly, giving more linear modulation — ideal when tyre grip is variable or when progressive trail braking is the priority. This is the kind of adjustment that previously required a different master cylinder entirely; the XS.16 consolidates it into a single, elegant mechanism you can set up in the garage before each session.
Folding Lever — Race-Proven Safety Detail
The folding brake lever is a small detail that earns its place every season. In a race incident or a paddock tip-over, the lever folds rather than snaps, keeping the braking system intact and the rider back out on circuit. For track day regulars and club racers alike, it is the kind of thoughtful engineering that distinguishes a true racing component from a sporting imitation.
