DescriptionThe whole story

A big naked like the KTM 990RC R stops with its front wheel and very little else. For the KTM 990RC R of 2025 that shape is the B005, a 102.2 by 42.0 mm face on a laser-cut backing plate. For the KTM 990RC R that means EX Race: race-level heat resistance without race-level disc wear.

Key Features

  • Heat spreads across the whole 102.2 by 42.0 mm face instead of concentrating at the leading edge
  • Supplied as a pack of two - the exact set the Brembo caliper of the 990RC R takes
  • Predictable in the wet, because the compound does not need temperature to start working on a 990RC R
  • Consistent friction from the first lap to the wear limit, so the braking marker set on a cold 990RC R still means the same thing when it is hot
  • No warm-up needed: the B005 works at the first cold stop of the day, which is why ZCOO sells EX Race for road as well as circuit use
  • Consistent lever travel as the pad thins, so the bite point on the 990RC R does not creep between services

Construction and Material Quality

There is nothing improvised about how a B005 is put together. The B005 plate is laser-cut from an alloy chosen for stiffness at working temperature, not at room temperature. On the 990RC R that translates into a lever position which does not creep as the pad thins.

Performance and Feel

Between roughly zero and 600 degrees the B005 holds a near-constant friction coefficient. Force follows the 990RC R lever from the first millimetre of travel rather than arriving in a step. For a 990RC R that is the difference between a hard stop and a fright.

Fitment and Compatibility

This reference is catalogued for the Brembo-equipped KTM 990RC R, 2025. Front axle only; the B005 has no rear counterpart in the ZCOO programme. The same B005 shape covers 117 further machines in the 2026 catalogue. 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.
