Nissin Forged 4-Piston Asymmetric Brake Caliper – 100MM Front Wheel Mount

Take your motorcycle's braking performance to the next level with this Nissin-style forged aluminum alloy brake caliper. Engineered specifically for front wheel applications, this 4-piston asymmetric caliper delivers confident, responsive braking with every squeeze of the lever. Whether you're upgrading a street bike or fine-tuning a track machine, this caliper is built to perform.

Key Features

Forged Aluminum Alloy Construction: High-grade aluminum alloy forging provides an excellent strength-to-weight ratio, ensuring long-lasting durability while keeping unsprung weight to a minimum.
4-Piston Design: Four pistons work in unison to apply even, balanced clamping force across the brake pad surface, delivering superior stopping power and precise brake modulation.
Asymmetric Configuration: The asymmetric caliper body is optimized for improved heat dissipation, reducing brake fade during extended or demanding riding sessions.
100MM Installation Lock Point: Precision-machined 100MM mounting holes ensure a secure, rattle-free fit on compatible front fork brackets, optimizing overall brake efficiency.
Front Wheel Braking Specific: Purpose-built for front wheel braking systems, this caliper is designed to maximize stopping performance where it matters most.

Why Upgrade to a 4-Piston Caliper?

Multi-piston calipers distribute hydraulic pressure more evenly across the brake pad, resulting in more consistent and responsive braking feel compared to single or twin-piston alternatives. The asymmetric body design further enhances thermal management, keeping brake performance consistent even under repeated hard braking.

Frequently Asked Questions

Q: What motorcycles is this 4-piston forged brake caliper compatible with?

A: This caliper is designed for motorcycles with a 100MM front fork mounting pitch. It is compatible with a wide range of street bikes, sport bikes, and track bikes that use a standard 100MM radial or axial mount bracket. Always verify your specific model's mounting dimensions before purchase to ensure a proper fit.

Q: What is the advantage of an asymmetric brake caliper design?

A: An asymmetric caliper body is shaped to allow improved airflow around the caliper during riding. This promotes faster heat dissipation from the caliper and brake fluid, reducing the risk of brake fade during repeated or prolonged braking — ideal for spirited street riding or track use.

Q: Is the caliper made from forged or cast aluminum?

A: This caliper is constructed from forged aluminum alloy. Forging produces a denser, stronger grain structure compared to casting, which translates to a lighter yet more durable component that can withstand the stresses of demanding braking scenarios.

Q: Does this caliper come with brake pads included?

A: The listing is for the brake caliper body only. Please source compatible brake pads separately based on your specific caliper and rotor specifications. Consult a qualified motorcycle mechanic for installation and pad selection guidance.
