Talos S78 Monoblock Brake Caliper Front Left P4 34/34 100mm | X78.100.HD.L

Engineered to deliver precise, confidence-inspiring braking lap after lap, the Talos S78 Monoblock front left brake caliper gives track-focused riders the consistent feel and heat resistance they need to push harder into every corner. With a 100 mm mounting pitch, four 34 mm titanium TIN-coated pistons and a hard-anodised monoblock body weighing just 583 g, this is a caliper built entirely around repeatable performance under extreme thermal load.

Key Features

• One-piece monoblock aluminium body for exceptional rigidity and minimal flex under hard braking
• Four 34 mm titanium pistons with TIN coating resist heat build-up and reduce internal friction for consistent pad actuation
• Hard-anodised surface finish for long-term corrosion resistance and durability through repeated race sessions
• Weighs only 583 g in the 100 mm configuration — an outstanding power-to-weight ratio for a four-piston radial caliper
• 30 mm offset and 100 mm mounting pitch ensure correct fitment across a wide range of performance motorcycles
• Refined lever feel and precise modulation allow confident, controlled braking at the highest speeds

Monoblock Construction

The S78's single-piece body eliminates the flex points inherent in two-piece caliper designs. By machining the caliper from a single billet of aluminium and finishing it with a hard-anodised surface, Talos achieves a stiffness-to-weight balance that translates directly into a firm, progressive feel at the lever — exactly what riders need when braking late and hard into a fast chicane.

Titanium TIN-Coated Pistons

All four 34 mm pistons are machined from titanium and finished with a TIN (titanium nitride) coating. Titanium's low thermal conductivity shields the brake fluid from heat migrating through the caliper body, while the TIN surface reduces bore friction and wear. The result is a brake that feels as sharp on lap fifteen as it did on lap one — critical for endurance racing and extended track days alike.

Hard-Anodised Finish

The hard-anodised surface treatment creates a dense, corrosion-resistant layer that stands up to brake dust, track grime and the temperature cycling that destroys lesser coatings. This finish is not purely cosmetic — it adds measurable surface hardness that protects the caliper body wherever it is most exposed to abrasion.
