DescriptionThe whole story▼

The GSX-R 1000 has used two engine generations in this listing: the WVCY of 2012 to 2016 and the WDM0 of 2017 to 2025 with variable valve timing. Gilles lists the OFC-20-15 with M20 x 1.5 thread for both.

Key Features

  • Thread M20 x 1.5, head diameter 29.5 mm
  • Distinctive Gilles design
  • All four anodised colour inserts included
  • Hexagon socket plus the enclosed tool for opening and closing
  • High-grade aircraft aluminium
  • No registration required, according to Gilles

Not for the 2026 GSX-R1000R

For the 2026 GSX-R1000R, Gilles lists the OFC-20-25 instead, which is a separate product.

Track use

This cap has no safety-wire holes; check your race rules if wiring is required.

Two generations, one cap

Even though the engine changed considerably with the 2017 model, the oil filler thread stayed the same in Gilles' list.

Road Approval

Gilles marks the OFC as not requiring registration on the Suzuki GSX-R 1000. The cap replaces the original one, and nothing has to be entered in the vehicle documents.

Scope of Delivery

One oil filler cap with M20 x 1.5; the kit includes the four inserts and the opening tool.

Fitting

Swap the caps with the bike upright and the engine cold. Hand-tight first, then snug with the tool; overtightening does nothing for the seal.
