HEL V1 Solid Billet 4 Piston Front Radial Brake Calipers (100mm / 108mm)

HEL V1 Solid Billet 4-Piston Front Radial Brake Calipers

The HEL V1 Solid Billet 4-Piston Front Radial Brake Calipers represent the next level in braking performance for riders who demand precision, strength, and road-to-track reliability. Built by HEL Performance in the UK, these calipers are machined from a single block of high-grade 6082-T6 aluminium billet, delivering exceptional rigidity, optimized fluid flow and reduced unsprung weight — a combination made for serious performance.

Whether you’re upgrading your superbike for track days, or refining a high-performance street build, the HEL V1 calipers offer crisp brake feel, fade-resistance, and the peace of mind that comes from race-tested engineering.

Choose the Correct Mounting Size

The HEL V1 calipers are offered in two mounting bolt spacings to suit different motorcycle front-fork & wheel configurations:

• 100 mm mounting spacing – Ideal for many European sportbikes and aftermarket bracket setups, offering compatibility with common front-end arrangements. 

• 108 mm mounting spacing – Designed to suit many Japanese sportbike models and forks with wider bolt patterns, giving you more flexibility when upgrading heavier bikes or those with larger rotors. 

Ensure you verify your fork mounting bolt spacing before selecting your caliper size.

Key Features

• Genuine HEL Performance V1 solid-billet 4-piston radial caliper

• Precision CNC-machined from 6082-T6 billet aluminium for unmatched structural performance 

• Available in 100 mm or 108 mm bolt spacings to match your bike’s front end

Fitment & Installation

These calipers integrate with standard front braking systems — verify your rotor diameter, thickness, and mounting bolt spacing (100 mm or 108 mm) before purchase. As with all high-performance braking systems, professional installation, correct torque on bolts, and proper hydraulic bleeding are strongly recommended.
