DescriptionThe whole story

The braking marker is the last thing an SRK 1051 RR rider gives away willingly. The B005 is ZCOO's shape for the Brembo caliper of the QJMotor SRK 1051 RR, 102.2 mm long and 8.05 mm thick. The mixture in this B005 is EXR: up to twenty percent more force in the second phase of braking.

Key Features

  • The B005 is dimensionally stable under the clamping load a Brembo caliper generates
  • Listed for the QJMotor SRK 1051 RR across 1 model year (2026)
  • Rotor-friendly by formulation: the SRK 1051 RR discs see a ceramic film rather than an abrasive
  • The B005 shape also serves 117 further machines in the ZCOO 2026 catalogue, so availability stays good
  • Stable friction from the first squeeze to the wear limit, so the SRK 1051 RR brakes the same on a cold morning and at the bottom of a pass
  • Resists glazing under sustained pressure, which is what ends most organic pads on an SRK 1051 RR

Construction and Material Quality

Look behind the friction face of the B005 and the engineering is all about stiffness. Sintering fuses the ceramic to the plate, which is what lets the B005 hold together where an organic pad has begun to break down. Together they remove the two things that normally end a sintered pad, and the B005 is built against both: fade at the top of the range, and the friction layer lifting away.

Performance and Feel

The mixture in the B005 changed in 2026, and so did the plate behind it. It is rated at or above the EXC Endurance compound it succeeds, and EXC already outlasted EX Race by roughly a factor of two. Which on an SRK 1051 RR is the whole reason to change compound in the first place.

Fitment and Compatibility

The 2026 listing puts the B005 on the QJMotor SRK 1051 RR for the 2026 model years. The same B005 shape covers 117 further machines in the 2026 catalogue. Nothing in the ZCOO range fits the rear axle of the SRK 1051 RR. Before ordering, check that your caliper takes a pad of 102.2 mm length and 42.0 mm height.

Road Approval

No ECE R90 type approval is documented for this pad. It appears neither in ZCOO's own catalogue nor on the European distributor's site, and no approval number is printed on the packaging data available to us. ZCOO itself describes the compound as suited to competition machines and road machines alike, but that is a description of the mixture, not a type approval. Until the distributor confirms an approval in writing, treat this as a track and competition part: in Germany a replacement brake pad without ECE R90 approval may not be fitted to a motorcycle used on public roads. Ask us before ordering if you need this clarified for your machine.
