DescriptionThe whole story▼
There is a moment on every naked bike where the rider asks for more brake than the chassis wants to give. On this machine the reference is the N004, 75.0 mm of friction face in the Nissin caliper. In the N004 the mixture is ceramic-sintered EX Race, mixed for a flat curve rather than a sharp first bite.
Key Features
- Supplied as a pack of two - the exact set the Nissin caliper of the GD125 EXIV takes
- Selected by ZCOO for the Hyosung GD125 EXIV out of the sixteen shapes in the 2026 programme
- No warm-up needed: the N004 works at the first cold stop of the day, which is why ZCOO sells EX Race for road as well as circuit use
- Stable friction from the first squeeze to the wear limit, so the GD125 EXIV brakes the same on a cold morning and at the bottom of a pass
- Country of origin Japan; ZCOO does not source its friction material outside its own plant
- The ceramic layer is sintered to the plate rather than pressed against it, which is what keeps the N004 together at the top of its temperature range
Construction and Material Quality
The N004 is built on the same platform as ZCOO's endurance-racing references. Bonding, not gluing: the ceramic layer of the N004 is fused to the plate under pressure. The result on the Hyosung GD125 EXIV is a pad that wears evenly rather than tapering from one edge.
Performance and Feel
On a GD125 EXIV the second half of a session is where EX Race earns its price. Across 5 model years of the GD125 EXIV the behaviour is the same, because the compound is. On the Hyosung GD125 EXIV that turns a violent event into a metered one.
Fitment and Compatibility
ZCOO catalogues the N004 for the GD125 EXIV of 2012 to 2016. 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. 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.
