DescriptionThe whole story

The SRT 450 RX teaches braking, and it teaches it through one front disc. The SRT 450 RX takes the B002: a 8.5 mm stack of ceramic-sintered material across 75.5 by 55.0 mm. The B002 in EX Race trim is the version ZCOO builds for riders who value feel over first bite.

Key Features

  • Shipped in ZCOO's own packaging with the ZRM-B002C code printed on it, so a repeat order needs no guesswork
  • Pad code ZRM-B002C, 75.5 mm long and 55.0 mm tall - a direct fit in the standard caliper
  • Backed by the ZCOO 2026 catalogue listing for the QJMotor SRT 450 RX, 2026
  • Part number Z-B002-EX, EAN 4950545750020
  • 75.5 by 55.0 mm friction face at 8.5 mm total thickness, cut for the Brembo caliper of the QJMotor SRT 450 RX
  • Wear stays even across the 75.5 mm of friction face rather than concentrating at the leading edge

Construction and Material Quality

What sits behind the friction material on a B002 matters as much as the mixture itself. The ceramic content is what lets the B002 form a protective film on an SRT 450 RX disc instead of abrading it. It is also why ZCOO can quote fade resistance beyond 600 degrees for the B002 without qualifying it.

Performance and Feel

There is nothing dramatic about the first squeeze of an EX Race B002, and that is deliberate. Force follows the SRT 450 RX lever from the first millimetre of travel rather than arriving in a step. The QJMotor SRT 450 RX does not need more force; it needs the same force every time.

Fitment and Compatibility

Fitment covers the QJMotor SRT 450 RX from 2026 to 2026 with the Brembo caliper. Before ordering, check that your caliper takes a pad of 75.5 mm length and 55.0 mm height. The same B002 shape covers 75 further machines in the 2026 catalogue. The reference is a front pad; ZCOO lists no rear equivalent.

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.
