DescriptionThe whole story▼

If the fork of your Triumph Thunderbird (2016–2017) is weeping oil, this SKF seal kit from Wilbers is the matching replacement. Per kit you seal one fork leg of the Thunderbird.

Key Features

  • Low friction for a sensitive fork
  • Protects the stanchion surface
  • Fork: Showa, 47 mm
  • One leg per kit; two kits for the complete fork
  • Patented SKF compound in the distinctive green colour

One Kit, One Leg

In the box: one oil seal and one dust wiper. Two kits cover the whole Showa, 47 mm fork of the Thunderbird.

Why Green

SKF designed the green seal around a patented base material. On the Thunderbird, it keeps the fork sealed without making the response stiff. On the Thunderbird's fork tubes the seal works gently.

Keeping the Thunderbird Fork Tight

The Showa, 47 mm fork of the Thunderbird relies on two seals per leg to keep oil in and dirt out. With fresh SKF seals the fork of the Thunderbird responds noticeably finer. For a cruiser like the Thunderbird, a sensitive fork is worth a lot.

Related Wilbers Parts

Pair the seals with Wilbers fork oil in the right viscosity. Opening the fork is also the chance to fit new Wilbers springs on the Thunderbird.

Signs of Worn Seals

Wipe the fork tubes of the Thunderbird clean and look again after a ride; fresh oil means a leaking seal. Oil on the brake disc or pads is a safety risk; replace leaking seals promptly. Seals are cheap compared with the work of opening the fork twice.

Fitting

Use new fork oil when you reassemble the fork.

Does It Fit Your Bike?

Wilbers specifies it for the Triumph Thunderbird from 2016 to 2017, vehicle type B16BA/BK01. It is matched to the Showa, 47 mm fork. Different fork versions may need a different seal; check the fork maker and size.
