The Performance Machine 125 x 4 Race Series Radial Mount Caliper with ARC technology is engineered for high-performance braking in powersports applications. Constructed from CNC-machined billet aluminum, this caliper offers exceptional rigidity, which translates into a consistent and crisp braking feel. Its design is optimized for radial mount applications with a 108mm bolt spacing, ensuring compatibility with a variety of motorcycle setups. The caliper is specifically designed to be used with .200-inch thick discs, providing reliable and efficient stopping power. Performance Machine’s innovative ARC (Advanced Radiant Cooling) technology enhances heat dissipation, allowing the caliper to maintain optimal performance even during extended or demanding riding sessions. This breakthrough in piston and caliper design addresses one of the most critical factors in high-performance braking: heat control, which helps prevent fading and maintains brake feel under stress. The caliper comes with chrome mounting hardware for easy installation and is compatible with both ABS and non-ABS systems, making it versatile for different motorcycle configurations. Made in the USA, this caliper embodies quality manufacturing standards and durability, ensuring long-lasting performance on the road or track. Whether you are upgrading your existing braking system or building a custom high-performance setup, this caliper offers the precision and cooling efficiency necessary for demanding riding conditions, all while maintaining a sleek gunmetal grey finish for a modern aesthetic.
