DescriptionThe whole story

Weight is the defining fact of a machine like the Indian Challenger 1890. ZCOO lists the B007 here, cut to 85.0 by 51.0 mm for the Brembo caliper carried by the Indian Challenger 1890. In EXR the Challenger 1890 gets the compound ZCOO now points endurance and sprint racers toward.

Key Features

  • Predictable in the wet, because the compound does not need temperature to start working on a Challenger 1890
  • Heat spreads across the whole 85.0 by 51.0 mm face instead of concentrating at the leading edge
  • Consistent lever travel as the pad thins, so the bite point on the Challenger 1890 does not creep between services
  • Initial bite in the order of EXC Endurance, with a progressive build-up that returns the modulation EXC traded away
  • Tested and specified for the 2020 to 2023 model years of the Indian Challenger 1890, not extrapolated from a neighbouring year
  • Sized for the braking energy a 1769 cc machine generates, not scaled down from a larger reference

Construction and Material Quality

The B007 is made by Okada Corporation in Japan. Expansion gaps between the friction blocks let the B007 material grow into the gaps when hot instead of building stress against itself. Both details exist so the B007 keeps its pressure distribution honest as it wears down.

Performance and Feel

The change from EXC to EXR is not only in the friction mixture. The reworked progression is what keeps the additional force usable at full lean. On a Challenger 1890 the front brake works hardest at the moments the rider least expects it.

Fitment and Compatibility

For the Challenger 1890 of 2020 to 2023 the B007 is the shape ZCOO lists. The same B007 shape covers 111 further machines in the 2026 catalogue. Nothing in the ZCOO range fits the rear axle of the Challenger 1890. Before ordering, check that your caliper takes a pad of 85.0 mm length and 51.0 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.
