Evotech Front Caliper Guards are sold in pairs for the BMW GS as the motorcycle has disc brake calipers on each side of the front wheel. We recommend these are fitted on both sides for maximum protection to your calipers and you can ride easier knowing both sides of the wheel are protected. The model-specific design of the brake caliper protectors ensures an accurate fit whilst the durable powder-coating and EP logos offer a discreet, stylish design.
