Galfer Brake Pads — Sur-Ron Ultra Bee (Zoom Hydraulic Caliper)
Brake Pads
Sur-Ron Ultra Bee uses Zoom hydraulic calipers with mineral oil — NOT DOT fluid. Galfer BFD-series OEM replacement pads for the Zoom caliper. Specific Galfer BFD part number not confirmed in catalog research — verify part number with ECR before ordering. Available in semi-metallic (standard) or ceramic race compound (rear only). Do NOT assume these fit Sur-Ron Storm Bee — Storm Bee uses a Zoom caliper but potentially a different model requiring verification.
