DescriptionThe whole story

On an unfaired machine like the Hyosung GT650 the rider's own body is part of the braking load. ZCOO answers with the N004, 75.0 by 55.3 mm of ceramic-sintered friction material cut for the Nissin caliper. The N004 in EX Race trim is the version ZCOO builds for riders who value feel over first bite.

Key Features

  • Low noise and low rotor scoring, which on a GT650 means the discs outlast several sets of pads
  • Machined, not moulded: the N004 plate is cut to the Nissin outline rather than pressed to an approximate one
  • Runs cooler at the disc than a conventional sinter, because the ceramic film it forms carries part of the load on the GT650
  • Direct replacement for the standard Nissin pad on the Hyosung GT650 - no shims, no spacers, no modification
  • Lever feel on the GT650 stays linear from the first millimetre of travel to full pressure
  • Suits the GT650 on the road as readily as on a circuit, which is what separates the ceramic platform from a pure race sinter

Construction and Material Quality

Every ZCOO reference, the N004 among them, is built around one idea: keep the friction face flat. On a face of 75.0 by 55.3 mm even a small amount of plate flex changes where the pressure lands. None of it is visible once the N004 is in the Nissin caliper, which is precisely the point.

Performance and Feel

The compound was specified for the whole temperature band a GT650 meets, not for the top of it. It works from cold without a warm-up lap and does not turn grabby once the N004 is hot. On an unfaired machine like the Hyosung GT650 that is a control argument, not a comfort one.

Fitment and Compatibility

ZCOO's fitment data gives the N004 for the GT650 built between 2015 and 2015. ZCOO lists no rear pad for the GT650. Before ordering, check that your caliper takes a pad of 75.0 mm length and 55.3 mm height. The same N004 shape covers 12 further machines in the 2026 catalogue.

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.
