Brembo 07KA21SP Prime Sintered Rear Brake Pads are designed for riders who want dependable stopping performance, consistent control, and long service life. Developed specifically for rear brake applications, these pads use a high-performance sintered compound that maintains a stable friction coefficient across a wide range of riding conditions. Whether you are commuting, touring, or riding aggressively, they provide predictable braking response in both dry and wet environments.
The sintered formulation delivers strong initial bite with smooth, progressive modulation, helping riders manage rear-wheel braking with confidence. Excellent heat resistance allows the pads to maintain reliable performance during repeated braking, demanding road use, and high-temperature operation. Their low-wear characteristics support extended pad life and dependable mileage while helping preserve consistent braking efficiency throughout the service interval. This makes them a practical upgrade over standard original-equipment-style pads for compatible Harley-Davidson and Kawasaki motorcycles.
Brembo 07KA21SP rear pads are compatible with select 2014-2017 Harley-Davidson Sportster models, including the XL1200CX Roadster, XL883N Iron 883, and XL883L SuperLow, as well as the 1996-1997 Kawasaki ZX750 Ninja ZX-7RR. Always verify the motorcycle model, year, and brake configuration before installation. Properly bed in new brake pads according to the motorcycle manufacturer’s recommendations to achieve optimal contact, control, and stopping performance. For riders seeking durable rear braking performance with a consistent feel, these Brembo Prime pads offer a reliable sintered-compound solution.
