DescriptionThe whole story

There is very little thermal mass in the front end of an KTM RC4R 250. The RC4R 250 takes the B002: a 8.5 mm stack of ceramic-sintered material across 75.5 by 55.0 mm. In EX Race form it is the compound an RC4R 250 rider can use from the first cold stop of the day.

Key Features

  • 75.5 by 55.0 mm friction face at 8.5 mm total thickness, cut for the Brembo caliper of the KTM RC4R 250
  • Low noise and low rotor scoring, which on an RC4R 250 means the discs outlast several sets of pads
  • The Brembo caliper spreads under peak pressure; the B002 plate is cut stiff enough to keep the friction face flat while it does
  • Consistent across the whole 1-year listing for the RC4R 250, so a used bike takes the same reference as a new one
  • The friction material and the B002 plate are made in the same Japanese plant
  • One pack holds the two pads for a single caliper - an RC4R 250 with twin front discs therefore needs two packs

Construction and Material Quality

Every ZCOO reference, the B002 among them, is built around one idea: keep the friction face flat. The B002 plate is cut to the Brembo window rather than trimmed down from a larger blank. None of it is visible once the B002 is in the Brembo caliper, which is precisely the point.

Performance and Feel

What the B002 in EX Race buys is predictability, not a headline figure. The lever pressure needed for a given deceleration barely moves as heat builds through a session on the RC4R 250. Which is what makes the B002 the sensible first upgrade on an RC4R 250.

Fitment and Compatibility

Listed by ZCOO for the KTM RC4R 250, model years 2020, on 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.
