RCB Universal Brake Fluid Tank Holder is a premium, high-strength mounting bracket engineered explicitly for custom handlebar configurations and radial master brake cylinder installations (such as the RCB S1 or S1-FL series). When upgrading to an aftermarket master cylinder that features an external reservoir pot, a highly rigid, adjustable mounting arm is critical to keep your hydraulic fluid perfectly stabilized.
Machined entirely from T6 billet aluminum, this holder replaces flimsy, generic stamped-metal tabs with a vibration-resistant, multi-axis adjustable support strut that prevents fluid aeration and complements your cockpit’s custom aesthetic.
Key Features
-
Premium CNC-Machined Billet Aluminum: Fully sculpted from a solid block of high-tensile T6 aluminum alloy. This structural material completely eliminates bracket flex and limits cockpit vibration, protecting your reservoir from fatigue cracking over time.
-
Multi-Axis Articulated Joints: Designed with flexible pivot points that allow you to adjust the precise tilt angle and height of your reservoir pot. This ensures the internal intake port remains fully submerged in fluid regardless of your handlebar rake or sweep angle.
-
Vibrant Hard-Anodized Resistance: Sealed in a deep, premium hard-anodized treatment (available in signature RCB Gold, Matte Black, Racing Red, Blue, and Silver). This finish provides heavy UV protection to prevent sun fading and resists chemical weathering from accidental brake fluid contact.
-
Vibration Isolation Spacer Geometry: Engineered with precision-fit socket shoulders that dampen low-frequency engine harmonies, preventing your brake fluid from foaming up or trapping unwanted micro-bubbles inside the master pump system.
-
Universal Bolt-On Compatibility: Features standard mounting diameters designed to bolt directly onto mirror mount threads, master cylinder clamp posts, or aftermarket triple-tree accessory brackets.
