The GMA ENGINEERING BY BDL Billet Brake Caliper delivers a high‑performance, lightweight solution for rear brake applications on classic street‑style motorcycles. Constructed from billet aluminum and finished with a long‑lasting anodized coating, the caliper is engineered for durability and precise heat dissipation. The kit includes hanger brackets and brake pads, and is designed for a 5/8" bore master cylinder, ensuring proper hydraulic flow and braking response. It is not compatible with older 3/4" bore Wagner or Kelsey‑Hayes die‑cast calipers, nor with imported stainless steel rotors, which could compromise performance.
Available in a range of classic styles and clear or black anodized finishes, the 10" rotor‑size, 2‑piston caliper is tailored for rear mounting on models from the 1973‑1980 BT era and beyond. Configurations include CALIPER RR 73‑80BT CL ANO, CALIPER RR 73‑80BT CL BLK, CALIPER RR 81‑84FX CL BLK, CALIPER RR86‑99FLT CL ANO, CALIPER RR85‑99FXR SM BLK, CALIPER FR73‑83FLH CL ANO, and CALIPER FT 74‑77FX CL ANO, among others. Each option retains the same core billet construction and anodized finish, providing a consistent, high‑quality braking experience across a broad range of vintage and modern street‑style motorcycles.
