DescriptionThe whole story

An RC4R 250 concentrates its braking heat rather than spreading it. The reference is the B002 - 55.0 mm of friction height over 75.5 mm of length, on the Brembo fitment the RC4R 250 uses. EXR reached the market in September 2026 and takes over from EXC Endurance in the B002 too.

Key Features

  • The B002 shape also serves 75 further machines in the ZCOO 2026 catalogue, so availability stays good
  • Machined, not moulded: the B002 plate is cut to the Brembo outline rather than pressed to an approximate one
  • Holds its friction level through the heat cycles an RC4R 250 front end goes through in a single hard ride
  • ZCOO specifies this reference for the KTM RC4R 250 directly, not by cross-reference from a similar machine
  • Shipped in ZCOO's own packaging with the ZRM-B002C code printed on it, so a repeat order needs no guesswork
  • The B002 is dimensionally stable under the clamping load a Brembo caliper generates

Construction and Material Quality

Look behind the friction face of the B002 and the engineering is all about stiffness. Heat enters a B002 at the friction face and has to leave through the plate, which is why the alloy matters as much as the mixture. For the rider of an RC4R 250 the whole of that engineering shows up as one thing: a lever that means the same on the last stop as on the first.

Performance and Feel

ZCOO quotes a figure for EXR that most pad makers avoid quoting at all. Better cold performance was the other half of the change, and on an RC4R 250 used on the road that matters more than the extra force. The KTM RC4R 250 does not need more force; it needs the same force every time.

Fitment and Compatibility

ZCOO catalogues the B002 for the RC4R 250 of 2020. The same B002 shape covers 75 further machines in the 2026 catalogue. Before ordering, check that your caliper takes a pad of 75.5 mm length and 55.0 mm height. Front axle exclusively - there is no rear B002.

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.
