DescriptionThe whole story▼

The Dax's 124 cc single is the same compact engine family as the Monkey's, and it sits in plain view below the pressed-steel frame. The Gilles OFC adds a coloured ring to its oil filler.

Key Features

  • Thread M20 x 2.5, head diameter 29.5 mm
  • Hexagon socket plus the enclosed tool for opening and closing
  • High-grade aircraft aluminium
  • Fitted in a few seconds, according to Gilles
  • Distinctive Gilles design
  • No registration required, according to Gilles

Type JB04

Gilles lists the OFC-20-25-1 for the Dax from 2022.

A classic touch

Silver or gold suit the Dax's retro look.

Small engine, easy upkeep

The 124 cc single needs little more than regular oil checks and changes, and many Dax owners do both themselves at home. A cap that opens cleanly with a hexagon key, and a coloured ring that makes the filler easy to spot, suit that kind of home maintenance.

Road Approval

No registration required, says Gilles, and no TÜV either: the OFC goes on the Honda ST125 Dax without an inspection and without any change to the papers.

Scope of Delivery

One oil filler cap with M20 x 2.5; 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.
