DescriptionThe whole story▼

The MT-10's crossplane four comes from the R1, retuned for more midrange torque. Gilles lists the OFC-27-30, with M27 x 3.0 thread, for its oil filler.

Key Features

  • Thread M27 x 3.0, head diameter 35.3 mm
  • Holes for a safety wire
  • High-grade aircraft aluminium
  • Fitted in a few seconds, according to Gilles
  • Distinctive Gilles design
  • No registration required, according to Gilles

RN45 and RN78

The listing covers the MT-10 and SP from 2016 and the RN78 from 2022.

Crossplane character

The crossplane crank gives the engine its uneven firing and its distinctive sound, and it is the heart of the MT-10's appeal.

Wire holes

Like every OFC-27-30, this cap has holes for a safety wire, which is useful if the MT-10 is taken to track days with strict technical rules.

Colours

Blue suits Yamaha's colours; silver and gold stand out on the dark engine, and red is included as well.

Road Approval

According to Gilles, the OFC oil filler cap needs no approval on the Yamaha MT-10; the description says plainly that no TÜV is required.

Scope of Delivery

One oil filler cap with M27 x 3.0; 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.
