The AdaptivMount Sportbike Mount Type D is designed with a combination of high strength steel and aircraft grade anodized aluminum. Patent pending Adapti-Sorb Anti-Vibration Technology greatly reduces vibrations transferred from the bike to the mounted gadget. The double ball-joint design provides a high degree of freedom for optimal positioning, easy adjustment, and simple installation.

The Sportbike Mount Type D is designed for most Ducati motorcycles.

Steering-stem nut needs to be removed to fit this.

How to Remove the Steering-stem nut From the Triple Tree

🔧 Tools Needed

• 30 mm socket → Steering-stem nut

• Torx T45 or T50 → Top-clamp pinch bolts

• Torque wrench (for reassembly)

• Soft towel (to protect top clamp)

Step-by-Step Removal

1. Loosen the fork-tube pinch bolts on the top triple tree

There are two pinch bolts (one on each side).

• Do not remove them completely.

• Crack them loose so the clamp releases tension from the centre nut.

If you do not loosen these, the centre nut will feel “seized”.

2. Remove the steering-stem nut

Use a 30 mm socket.

• Turn anticlockwise.

• This nut sits on a splined shaft, so it may feel snug until broken free.

Nothing will spring out — the lower triple clamp holds the actual preload and bearings.

3. Lift the centre insert

Once the nut is off:

• The centre piece (the decorative / cover plate with holes) lifts out.

• Some models have a rubber O-ring — lift gently.

• On V4S/V4R, this piece may also house the Öhlins preload adjuster sockets.

4. Inspect for a circlip (on some variants)

Some Panigale V4 top clamps have a retaining circlip under the cover.
If yours has one:

• Use picks/circlip pliers.

• Remove the clip → then the centre section comes free.

Most 2020–2021 V4 Base & V4S do not have the circlip — it's just compression-fit under the top nut.
