G'Day,

Pitbikes are a different due to 10",12",14" wheels, many different brake calipers will fit easily without modifications.
Will be using 8" wheels and brake caliper choices are quite limited due to size to one piston / two piston calipers: Brembo, AP-Racing, Nissin, Tokico or one-off custom CNC brake calipers.
