DescriptionThe whole story

Learning to brake late on a 450 SMR is easier with a pad that behaves predictably. ZCOO cuts the B005 at 102.2 by 42.0 mm to fill the Brembo caliper window of the 450 SMR. What is new on the KTM 450 SMR is the compound - EXR, on a backing plate alloy specified with it.

Key Features

  • Stable friction from the first squeeze to the wear limit, so the 450 SMR brakes the same on a cold morning and at the bottom of a pass
  • Low noise and low rotor scoring, which on a 450 SMR means the discs outlast several sets of pads
  • Part number Z-B005-EXR, EAN 4950545771773
  • Selected by ZCOO for the KTM 450 SMR out of the sixteen shapes in the 2026 programme
  • Rotor-friendly by formulation: the 450 SMR discs see a ceramic film rather than an abrasive
  • The friction material and the B005 plate are made in the same Japanese plant

Construction and Material Quality

Look behind the friction face of the B005 and the engineering is all about stiffness. On a face of 102.2 by 42.0 mm even a small amount of plate flex changes where the pressure lands. On the 450 SMR that translates into a lever position which does not creep as the pad thins.

Performance and Feel

Durability is the quiet part of the EXR argument. EX Race is the control mixture; EXR takes the harder bite EXC was known for and rebuilds the progressiveness around it. On a light machine the tyre sets the limit long before the B005 does, so consistency beats power.

Fitment and Compatibility

ZCOO catalogues the B005 for the 450 SMR of 2013 to 2025. Before ordering, check that your caliper takes a pad of 102.2 mm length and 42.0 mm height. The B005 is a front pad only. The same B005 shape covers 117 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.
