DescriptionThe whole story▼

The Ninja 300 is a popular first sports bike and a regular on track days, where the oil level is checked before each outing. The Gilles OFC-30-15 replaces the filler cap with a machined one, M30 x 1.5, with a 39.5 mm head and one of four anodised inserts.

Key Features

  • Thread M30 x 1.5, head diameter 39.5 mm
  • High-grade aircraft aluminium
  • Fitted in a few seconds, according to Gilles
  • Distinctive Gilles design
  • All four anodised colour inserts included
  • No registration required, according to Gilles

Type EX300

Listed for 2013 to 2017.

Track days

At the circuit, the enclosed tool opens the cap quickly for a top-up between sessions, and the anodised insert makes the cap easy to spot.

Road Approval

According to Gilles, the OFC oil filler cap needs no approval on the Kawasaki NINJA 300; the description says plainly that no TÜV is required.

Scope of Delivery

The OFC cap with M30 x 1.5, four coloured inserts to choose from, and the Gilles tool.

Fitting

With the engine off and cool and the bike upright, clean around the filler opening so no dirt falls into the engine. Unscrew the original cap, screw the OFC in by hand and tighten it with the supplied tool; firm is enough, because overtightening does nothing for the seal. Fit the insert colour you want and check the oil level as usual.
