DISC BRAKE BIKE HERO XTREME 200S REAR

The Disc Brake Bike Hero Xtreme 200s Rear delivers instant stopping power, exceptional thermal fade resistance, and smooth, predictable brake lever modulation for your motorcycle or scooter. Manufactured to stringent OEM metallurgical standards, this heavy-duty stainless steel brake disc rotor replaces scored, warped, or thinned factory discs, eliminating brake shudder, lever pulsation, and extended stopping distances across all riding conditions.

Workshop Guide & Diagnostic Standards for Disc Brake Bike Hero Xtreme 200s Rear

Upgrading your vehicle with this precision-ground Disc Brake rotor ensures maximum braking efficiency, prevents high-speed brake fade, and protects your brake caliper pistons and pads from thermal damage.

1. High-Carbon Heat-Treated Stainless Steel Metallurgy

This brake disc rotor is precision stamped from premium Japanese SUS420 martensitic high-carbon stainless steel sheet. Quenched and tempered to HRC 36–40 hardness, the rotor provides superior tensile strength and surface abrasion resistance against aggressive semi-metallic and sintered brake pads. In addition, the balanced grain structure prevents surface micro-cracking and deformation under severe emergency braking from triple-digit speeds.

2. Cross-Drilled Cooling Vents & Wave Outer Geometry

Computer-engineered with precision CNC cross-drilled holes and wave outer perimeter contours, this rotor maximizes airflow turbulence to dissipate intense frictional heat rapidly. The ventilation holes continuously evacuate vaporized friction resins and moisture films, ensuring instant, fade-free pad bite during wet monsoon highway riding and aggressive downhill descents.

3. Double-Disc Precision Surface Grinding & Zero Runout

Both friction contact faces undergo simultaneous double-disc CNC surface grinding to achieve absolute surface parallelism. With total indicator runout (TIR) held under 0.05 mm and disc thickness variation (DTV) controlled below 0.01 mm, this rotor completely eliminates annoying brake lever pulsation, front-end handlebar judder, and uneven pad wear.

4. Anti-Corrosion Zinc Electroplating & Hub Cavity Protection

The rotor hub mounting flange and non-swept surface areas are treated with an advanced anti-corrosion zinc electroplating and phosphate passivation seal. This impermeable protective layer withstands severe salt spray, acidic road wash, and monsoon humidity, preventing unsightly red-rust accumulation on your alloy wheel hub assembly.

5. Factory PCD Mounting Hole Alignment & Chamfered Edges

The central hub bore and mounting bolt pitch circle diameter (PCD) are CNC-machined to original factory tolerances for an effortless, direct bolt-on fitment. Precision chamfered bolt holes prevent stress concentration risers and ensure flush seating of high-tensile disc mounting bolts without thread binding.

6. Thermal Expansion Relief & Anti-Warpage Architecture

The rotor features engineered expansion slots along the inner and outer circumferences that allow the friction ring to expand and contract symmetrically under rapid heating cycles. This stress-relief design prevents radial dishing and conical distortion, preserving true planar alignment throughout the service life of the rotor.

7. Workshop Installation Protocols & Bedding-In Guidelines

Workshop technicians must clean both rotor surfaces thoroughly with solvent-based brake cleaner to remove transit anti-rust oil coatings before installation. Always install fresh brake pads when replacing the disc rotor. Tighten high-tensile disc mounting bolts in an alternating crisscross pattern using thread-locking compound, torquing to manufacturer specifications. Guide the rider through a 100-kilometer progressive bedding-in protocol, avoiding panic stops to establish a uniform pad material transfer layer on the rotor face.
