DescriptionThe whole story

Learning to brake late on a 321RR is easier with a pad that behaves predictably. The reference is the B007 - 51.0 mm of friction height over 85.0 mm of length, on the Brembo fitment the 321RR uses. In the B007 the mixture is ceramic-sintered EX Race, mixed for a flat curve rather than a sharp first bite.

Key Features

  • Heat spreads across the whole 85.0 by 51.0 mm face instead of concentrating at the leading edge
  • The friction blocks are separated so the B007 material can expand into the gaps rather than against itself
  • Tested and specified for the 2023 to 2025 model years of the Kove 321RR, not extrapolated from a neighbouring year
  • Resists glazing under sustained pressure, which is what ends most organic pads on a 321RR
  • Ceramic-sintered EX Race compound: on the 321RR the braking force rises in proportion to lever pressure instead of snapping in
  • Selected by ZCOO for the Kove 321RR out of the sixteen shapes in the 2026 programme

Construction and Material Quality

What sits behind the friction material on a B007 matters as much as the mixture itself. Bonding, not gluing: the ceramic layer of the B007 is fused to the plate under pressure. That is why the B007 holds a consistent contact patch deep into its service life.

Performance and Feel

EX Race trades a little initial aggression for a friction level that does not move on the Kove 321RR. Force follows the 321RR lever from the first millimetre of travel rather than arriving in a step. Which is what makes the B007 the sensible first upgrade on a 321RR.

Fitment and Compatibility

The 2026 listing puts the B007 on the Kove 321RR for the 2023 to 2025 model years. Before ordering, check that your caliper takes a pad of 85.0 mm length and 51.0 mm height. The same B007 shape covers 111 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.
