HEL 84mm Solid Billet 2-Piston Rear Axial Brake Caliper

The HEL Performance 84mm Solid Billet 2-Piston Rear Axial Brake Caliper is engineered for riders who demand consistent rear-end control, precision braking feel, and uncompromising build quality. Machined from a solid block of 6082-T6 aluminium billet, this caliper delivers outstanding rigidity and heat stability — giving you smooth, predictable braking performance on the road and the racetrack.

Designed for motorcycles that use an 84mm axial rear mounting system, this premium 2-piston caliper provides a significant upgrade over cast OEM rear calipers, offering improved modulation, lighter weight, and a cleaner, more compact profile.

Performance & Engineering

Every HEL billet caliper starts as a single block of aerospace-grade aluminium. Through multi-axis CNC machining, the caliper body is sculpted to achieve the perfect balance of strength, precision, and weight reduction.
The two piston configuration delivers reliable pressure distribution for stable rear braking without locking or fade — ideal for sport riding, endurance builds, and track setups where rear brake feel is essential.

The rear caliper’s tight tolerances, stainless-steel pistons, and internally optimised fluid galleries ensure exceptional hydraulic efficiency and consistent lever behaviour, even under prolonged heat cycles.
