RCB S1-FL Replacement Lever (Right Hand Side) – Gloss Black is a high-performance control component engineered exclusively as a direct-fit replacement blade for the RCB S1-FL Master Brake Pump Series.
Unlike the standard S1 series, the S1-FL relies on a specific layout featuring a collapsible folding mechanism. If you take a spill on the track or the street, this right-hand replacement lever restores your front braking layout back to factory specification without requiring a full purchase of a brand-new master cylinder master assembly.
Key Features
-
90° Collapsible Folding Design: Engineered with a robust pivot hinge that allows the lever blade to fold upward up to 90 degrees during an impact. This drastically reduces the likelihood of the lever snapping or bending during low-sides or stationary drops.
-
Forged Alloy Strength: Crafted via a high-density forging process rather than generic casting, providing superior grain structure density and impact resistance compared to standard aftermarket blades.
-
Hard Anodized Black Finish: Treated with a heavy-duty, hard-anodized deep black coating. This chemical bonding prevents fading from UV exposure and resists corrosive damage from harsh brake fluids (DOT 4).
-
Ergonomic Span Adjustment: Features an inline dial mechanism, allowing you to fine-tune the lever’s starting distance from the handlebar grip to optimize leverage for your specific hand size.
