MXS GP4 Four-Piston CNC Motorcycle Brake Calipers | 100mm Universal

MXS GP4 Track-Grade Four-Piston Radial Motorcycle Brake Calipers

Upgrade your motorcycle's braking performance with the MXS GP4 Four-Piston Radial Brake Calipers — engineered for riders who demand precision, durability, and style. Whether you're commuting daily or pushing hard on the track, these CNC-forged calipers deliver consistent, linear braking force with outstanding feel and control.

🔩 GP4 Track-Grade Four-Piston Architecture

Featuring four synchronised pistons, the MXS GP4 delivers uniform, linear braking force across the full pad surface. The result is a clear, controllable brake feel that helps shorten stopping distances and significantly improves riding confidence — lap after lap or commute after commute.

🏗️ Integrated Forging + CNC Precision Milling

The caliper body is forged from a single piece of high-strength aluminium alloy, then precision-milled on multiple axes for exact tolerances. This construction produces a shell with exceptional rigidity, far superior impact resistance, and deformation resistance compared to standard cast calipers. The lightweight design also reduces unsprung mass, improving suspension response and overall handling agility.

📐 100mm Standard Mounting — Broad Compatibility

The fixed 100mm locking hole spacing makes these calipers directly compatible with a wide range of electric motorcycles, electric light motorcycles, and the vast majority of scooters — including popular brands like No. 9 and Xiaoniu. No adapter bracket required, no drilling, no grinding — simply align with existing holes for a clean, straightforward installation.

🌬️ Streamlined Hollow Heat-Dissipation Structure

The unique hollow streamlined body design promotes active air circulation around the caliper, rapidly dispersing frictional heat generated during intensive or prolonged braking. This keeps brake performance consistent even during extended downhill runs, preventing the thermal fade that plagues lesser calipers.

🔒 Precision-Sealed Hydraulic Circuit

High-temperature-resistant oil seals combined with precision-machined piston components ensure zero oil leakage even under long-term, high-intensity use. Hydraulic pressure remains stable and consistent, so your brake feel stays firm and predictable — never getting soft or spongy over time.

✨ Premium CNC Metal Finish

Multi-angle CNC milling creates striking three-dimensional contour lines with a refined metal brushed texture and an embossed MXS brand logo. These calipers don't just perform — they make a visual statement that complements any performance motorcycle build.

🛞 High-Performance Brake Pads Included

Each set includes dedicated high-performance brake pads with a stable friction coefficient across a wide temperature range. Quiet operation, extended wear life, and gentle treatment of your brake disc mean lower long-term maintenance costs and a consistently smooth braking experience.

Frequently Asked Questions

Q: What motorcycles are compatible with the MXS GP4 four-piston brake calipers?

A: The MXS GP4 calipers use a standard 100mm mounting hole spacing, making them directly compatible with most electric motorcycles, electric light motorcycles, and the vast majority of scooters and pedal motorcycles. No adapter bracket is needed — they bolt directly to existing mounting points on compatible models.

Q: Are the MXS GP4 calipers suitable for both left and right sides?

A: Yes. The MXS GP4 calipers are designed as a universal left and right fitment, so a single purchase covers both sides of your motorcycle's braking system, ensuring balanced, symmetrical performance.

Q: Do the calipers come with brake pads?

A: Yes. Each set includes dedicated high-performance brake pads engineered specifically for the GP4 caliper. They offer a stable friction coefficient across temperature ranges, quiet operation, and extended wear life that's gentle on brake discs.

Q: How does the hollow streamlined design prevent brake fade?

A: The caliper's hollow streamlined body channels airflow directly around the caliper housing during riding, dramatically accelerating heat dissipation. This keeps operating temperatures lower during sustained or intense braking, maintaining consistent braking feel and preventing the performance degradation associated with excessive heat buildup.

Q: What material are the MXS GP4 calipers made from?

A: The calipers are constructed from high-strength aluminium alloy — first forged as a single integrated piece, then precision-machined via multi-axis CNC milling. This process yields a body that is both exceptionally rigid and lightweight, outperforming standard cast aluminium calipers in durability and deformation resistance.
