DescriptionThe whole story▼

A set of covers for the openings beside the cylinder heads, high on the engine where the frame bolts to it. Fullsix supplies them together because that is where they belong: two pieces in the same sight line, flanking the same casting.

Key Features

  • Supplied as a set, not singly
  • Mounts shared between engine and frame
  • Autoclave-cured carbon, five versions
  • Streetfighter V4, 2025 and 2026

Weave Direction Is Visible Here

Carbon cloth has a grain, and how it falls around a curve differs slightly between production runs. On parts hidden behind a fairing nobody would ever know. These two sit a hand's width apart in the open on a naked motorcycle, and a mismatch between them is the kind of thing an owner sees every time and a visitor never does. Ordering the set avoids it.

Look at Both Photograph Sets

Fullsix shows these loose on white and fitted to a machine. The loose shots make them look like flat panels; on the bike they are clearly recessed pieces with depth. Worth a minute before ordering, because the shape is not obvious from one view alone.

Fitment and Compatibility

Ducati Streetfighter V4, 2025 and 2026, and the Panigale V4, V4 S and V4 R. The single lower left cover is MD-V425-C76.

Road Approval

No road-traffic approval is documented by Fullsix for the set.
