RCB E2 SERIES BRAKING SYSTEM
RCB S1 SERIES BRAKING SYSTEM
RCB R34 4-Piston Radial Caliper (Universal) is a high-performance monoblock brake caliper engineered to deliver superbike-grade stopping power to street, track, and custom motorcycles. Fitted with 34mm dual-opposed pistons and pre-installed premium sintered brake pads straight out of the box, this radial caliper provides incredible structural rigidity, razor-sharp initial bite, and outstanding resistance to thermal fade.
Key Features
Includes High-Performance Sintered Brake Pads: Comes ready to install with pre-fitted sintered metallic brake pads. Sintered compounds fuse metallic particles under extreme heat and pressure, providing maximum friction coefficient (HH rated), instant stopping torque, and exceptional durability under aggressive track or high-speed braking.
34mm Oversized Pistons: Features four 34mm opposed pistons with drilled, heat-dissipating titanium/chrome-plated finishes to distribute even clamping pressure across the sintered pads while keeping fluid temperatures low.
Radial Mounting Architecture: Mounts perpendicular to the axle to eliminate caliper flex under heavy braking loads, delivering direct, uncompromised lever feedback and precise modulation.
High-Rigidity Monoblock Body: Precision CNC-machined from lightweight, high-strength aluminum alloy to reduce unsprung weight at the front wheel while maximizing structural integrity.
Universal Radial Fitment: Available in standard 100mm and 108mm radial mounting pitches for both Left-Hand (LH) and Right-Hand (RH) setups.
Universal Vehicle Compatibility & Fitment
Because this is a Universal Radial Caliper, mounting it onto standard axial forks requires a model-specific radial adapter bracket matching your fork spacing and brake rotor diameter:
100mm / 108mm Radial Spacing: Fits a wide array of sportbikes and custom setups (Yamaha YZF-R3/R15, MT-15, Aerox, Sniper 150/160, KTM Duke/RC series, Honda CBR series, and custom superbike builds).
Pad Replacement Standard: Uses the popular 4-pad radial configuration. When replacing the included sintered pads in the future, it is fully compatible with Vesrah SD-9031, Vesrah VD-9031JL, or equivalent Brembo 4-pad radial sintered pads.

Why Sintered Pads Come Standard
Unlike organic or semi-metallic pads, sintered metal pads excel in extreme heat environments. They do not glaze easily during repeated hard deceleration, making them the preferred choice for aggressive street riding, stunt performance, and track days where fade resistance and firm lever feel are paramount.

Product Structural Form
The caliper body showcases a rigid, split-half bolted construction with a wide-open top bridge to allow massive airflow directly over the brake pads. The radial mounting lugs are precision-machined to ensure perfectly square alignment with the brake rotor, guaranteeing parallel pad wear and zero rotational flex.
Braking Safety Notice: Installing a new brake caliper involves opening the hydraulic braking system. Any trapped air in the lines will result in complete brake failure. If you are not experienced in bleeding hydraulic brakes, this installation must be performed by a certified motorcycle mechanic. Always thoroughly wash away any spilled brake fluid with soapy water, as it is highly corrosive to paint and plastics.
