  • Distinctive Gilles design

  • Hexagon socket plus the enclosed tool for opening and closing
  • High-grade aircraft aluminium

Type SC89

Gilles lists the OFC-20-25-1 for the NT1100 of 2025.

Touring routine

The tool fits easily in the luggage for top-ups on the road.

Shared engine

The NT1100's twin also powers the Africa Twin and the Rebel 1100, all three with the same M20 x 2.5 filler thread.

Road Approval

Gilles marks the OFC as not requiring registration on the Honda NT1100. The cap replaces the original one, and nothing has to be entered in the vehicle documents.

Scope of Delivery

The OFC cap with M20 x 2.5, four coloured inserts to choose from, and the Gilles tool.

Fitting

With the engine off and cool, unscrew the original filler cap and screw the OFC in by hand. Tighten it with the supplied tool; firm is enough. Choose the insert colour you want and check the oil level as usual.
