JT Brake Rotor — Yamaha Front (JTD4103SC01)
Product Details

JT's competition-grade stainless rotors with the patented conical self-cleaning hole pattern — the disc you want when you're racing through mud, sand, or wet grass.

  • Patented conical self-cleaning hole design (GB Patent 2476859) — unique hole geometry pushes pad debris and grit clear of the friction surface every revolution.
  • Fully heat-treated stainless steel, machined to tight tolerances and engineered to resist warping at sustained high temperatures.
  • Race-tested compatible with all three pad chemistries — full sintered, semi-sintered, and organic — without modification.
  • Specially machined surface geometry enhances heat dissipation through the disc face.
  • Premium-quality replacement for modern off-road, motocross, and dual-sport models.
  • Consistent braking performance in wet, muddy, and dry conditions.
