Talos CNC ST Radial Brake Master Cylinder 16mm | ST.16

The Talos ST.16 brings genuine racing-master-cylinder technology to bikes that see daily duty. CNC-machined from billet aluminium, fitted with a folding lever and a built-in brake light switch, it is engineered for riders who want a consistent, confidence-inspiring brake feel every single ride — whether that is the morning commute, a spirited weekend blast, or a track day.

Key Features

• CNC-machined billet aluminium body — black anodised for corrosion resistance and a clean, purposeful look
• 16 mm piston bore delivers strong, well-defined lever pressure ideally matched to large four-piston and monoblock brake calipers
• Fixed lever ratio with a 19 mm pivot point gives a predictable, harmonious brake feel that inspires confidence on the road
• Folding lever absorbs low-speed drops and carpark tumbles without snapping, keeping you riding instead of waiting for parts
• Integrated brake light switch — plug straight in, no extra hardware or wiring adaptors required
• Hard-anodised aluminium piston, titanium bleeder and stainless steel clamp and pivot bolts throughout for long service life
• Click-adjustable lever reach suits a wide range of hand sizes without tools

Built for the Road, Proven on the Track

The ST series shares its engineering DNA with Talos race-specification master cylinders, re-tuned for street and performance riding. The body is precision-machined from solid billet aluminium, giving a rigidity that cheap cast units simply cannot match. That stiffness translates directly into consistent hydraulic pressure and a brake point you can rely on lap after lap — or junction after junction.

Weighing just 360 g, the ST.16 adds negligible mass while noticeably improving the quality of every braking input. The hard-anodised piston resists heat and wear over extended use, and the titanium bleeder saves weight at the caliper end of the system. Every fastener is stainless steel, so there is no corrosion creeping in after winter riding.

The 16 mm Bore Advantage

Master cylinder bore size directly determines how much hydraulic force your lever generates. The 16 mm bore of the ST.16 is the sweet spot for sport and superbike applications: it produces enough pressure to work large four-piston radial calipers and monoblock units with authority, while still leaving enough lever travel for progressive, nuanced modulation. The result is a firm, well-located bite point with the sensitivity to trail-brake confidently into corners.

Fixed Ratio — Consistent Feel Every Time

Unlike adjustable-ratio designs, the ST series uses a fixed lever ratio referenced to a 19 mm pivot point. On the road this is a genuine advantage: the brake feel is identical every time you reach for the lever, building muscle memory and reducing fatigue on longer rides. For occasional track days the consistent response is equally welcome, letting you focus on braking markers rather than compensating for a variable lever.

Everyday Practicality Built In

The folding lever is not a cosmetic feature — it is practical insurance. A brief contact at low speed that would destroy a rigid lever simply folds and snaps back into place. The integrated brake light switch means the ST.16 is a genuine bolt-on upgrade with no need to fabricate switch mounts or splice wiring. Click-adjust lever reach means the right hand position is dialled in within seconds, every time.
