DescriptionThe whole story

A 450 SMR concentrates its braking heat rather than spreading it. The reference is the B005 - 42.0 mm of friction height over 102.2 mm of length, on the Brembo fitment the 450 SMR uses. In the B005 the mixture is ceramic-sintered EX Race, mixed for a flat curve rather than a sharp first bite.

Key Features

  • No ECE R90 type approval is documented for this compound - treat the B005 as a track and competition part
  • Pad code ZRM-B005C, 102.2 mm long and 42.0 mm tall - a direct fit in the standard caliper
  • Even pressure distribution across the 102.2 by 42.0 mm face from new to the wear limit
  • 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
  • Rotor-friendly by formulation: the 450 SMR discs see a ceramic film rather than an abrasive
  • Holds its friction level through the heat cycles a 450 SMR front end goes through in a single hard ride

Construction and Material Quality

Construction on the B005 follows ZCOO's racing practice throughout. On a face of 102.2 by 42.0 mm even a small amount of plate flex changes where the pressure lands. Everything about the B005 plate is there to stop the friction face going out of true.

Performance and Feel

Riders moving to EX Race from an OEM organic pad usually describe the 450 SMR's brake as becoming quieter rather than stronger. It works from cold without a warm-up lap and does not turn grabby once the B005 is hot. Which is what makes the B005 the sensible first upgrade on a 450 SMR.

Fitment and Compatibility

ZCOO's 2026 catalogue lists this reference for the KTM 450 SMR across 13 model years (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.
