RCB E2 SERIES BRAKING SYSTEM
RCB S1 SERIES BRAKING SYSTEM
RCB Brake Disc E2 Series (230mm, Front) is a high-performance aftermarket brake rotor engineered by RCB specifically for Yamaha NMAX 155 and Aerox 155 scooter platforms. Crafted from heat-treated, high-grade stainless steel, this front rotor delivers exceptional thermal stability, elevated pad friction, and extended service life under heavy daily commuting and spirited riding.
Featuring an optimized wave pattern and diagonal ventilation slots, the E2 Series rotor rapidly evacuates heat, water, and friction dust, drastically reducing thermal brake fade and maintaining crisp, consistent lever feel.
Key Features
Heat-Treated Stainless Steel: Manufactured from specialized stainless steel alloy treated for high tensile strength, preventing warping and surface discolouration under extreme heat.
Performance Wave & Slotted Profile: Machined wave perimeter and ventilation slots continuously clean the brake pad surface, purge water/debris, and maximize airflow for quick cooling.
Anti-Fade Braking Power: Maintains stable friction performance during prolonged braking, steep descents, or high-speed urban riding.
Lightweight Structural Design: Removes unnecessary material along the outer profile to lower unsprung weight, enhancing front suspension agility and steering response.
Direct Plug-and-Play OEM Replacement: Precision 230 mm outer diameter with exact hub-centering and 3-bolt mounting dimensions for quick installation using factory front calipers and brackets.

Product Structural Form
The E2 Series front disc consists of a solid, single-piece heat-treated stainless steel plate precision-cut via high-energy lasers. The outer braking track features smooth wave-contoured edges and strategically angled ventilation channels to disrupt thermal buildup. The center mounting hub is machined to mirror factory tolerances, ensuring zero lateral runout and elimination of brake lever pulsation.
Operational Safety Notice: Always apply medium-strength thread-locking compound to disc rotor mounting bolts before final torquing. Never contaminate the new rotor friction track with grease or oil during installation. Clean the disc surface with solvent-free brake cleaner prior to riding, and allow 50 km to 100 km for full friction pad bedding.
