UGR Sports Edition Shark Fin 4-Piston Brake Caliper

Take your motorcycle or electric bike's braking performance to the next level with the UGR Sports Edition Large Radiation Shark Fin Brake Caliper. Engineered for riders who demand track-grade stopping power with street-ready reliability, this four-piston aluminum alloy caliper combines precision CNC forging, advanced heat dissipation, and a double oil-seal design — all wrapped in a razor-sharp black-and-gold aesthetic.

🏁 Track-Grade Four-Piston Braking

Competitive 4-piston structure: Delivers smooth, linear braking feel with exceptional modulation. Gradually apply pressure for controlled deceleration, or squeeze hard for decisive stopping — perfect for both daily commuting and spirited riding.
100mm standard locking point: Large-radius layout generates greater braking torque for confident, simultaneous front-and-rear stopping power.
Zero-delay brake response: Optimized bidirectional oil circuit with strategically positioned inlet and exhaust ports ensures immediate, direct hydraulic pressure transmission.

🔥 Shark Fin Heat Dissipation Design

External fin-shaped structure: The signature shark fin radiator fins dramatically increase surface area, accelerating heat transfer and maintaining stable braking force even during sustained, aggressive braking sessions.
Thermal fade suppression: Long-term continuous braking stays consistent — no fading, no unpredictability, just repeatable stopping performance lap after lap.

✨ One-Piece CNC Forged Aluminum Alloy Construction

High-strength forged aluminum body: Precision CNC-machined from a single billet for maximum rigidity with minimal weight. Impact-resistant and warp-resistant under extreme load.
Black-and-gold competitive finish: Matte black pump body paired with a gold oil nozzle and the UGR brand logo. Sharp, aggressive lines that complement any custom build or modification style.
Hard anodized surface treatment: Anti-oxidation, wear-resistant coating ensures the caliper looks great and performs reliably through years of use without fading or rusting.

🛡️ Double Oil-Seal Safety System

Imported dual oil seals: High-performance seals are anti-aging, heat-resistant, and cold-resistant — effectively preventing oil leakage and air infiltration in wet weather, high-temperature, or low-temperature conditions.
Universal oil pipe interface: Compatible with most standard-spec brake oil lines for maximum fitment flexibility across a wide range of motorcycle and e-bike builds.
Rigorous factory quality testing: Every caliper undergoes high-pressure sealing tests, oil pressure tests, and durability validation before leaving the factory.

Frequently Asked Questions

Q: What motorcycles or electric bikes is this UGR shark fin brake caliper compatible with?

A: The UGR Sports Edition Shark Fin Brake Caliper uses a 100mm standard locking point and a universal oil pipe interface, making it compatible with a wide range of motorcycles, electric motorcycles, and e-bikes that use standard brake oil line fittings. We recommend verifying your current caliper mount spacing before purchasing.

Q: What makes the four-piston design better than a standard two-piston caliper?

A: A four-piston caliper applies clamping force more evenly across the entire brake pad surface, resulting in more linear, consistent braking feel with superior modulation. This means smoother deceleration at lower inputs and stronger, more confident stopping at full squeeze — ideal for both street riding and track use.

Q: How does the shark fin heat dissipation structure work?

A: The external shark fin-shaped fins greatly increase the caliper's total surface area exposed to airflow. As you ride, air passes over and through these fins, carrying heat away from the caliper body much faster than a conventional smooth-body design. This helps suppress thermal fade during sustained or aggressive braking, keeping stopping performance consistent.

Q: Is the hard anodized finish durable for all-weather riding?

A: Yes. The hard anodizing process creates a thick, dense oxide layer on the aluminum surface that is highly resistant to corrosion, oxidation, scratching, and UV fading. The caliper is designed to withstand exposure to rain, road grime, and temperature extremes while maintaining its appearance and structural integrity over the long term.
