DescriptionThe whole story▼

Kawasaki builds the ZX-10RR in small numbers as the machine its race programme is homologated from, and most of them spend their lives between a paddock and a trailer. Some do not. PSK3 is the Bonamici Racing upper fork yoke for owners in the second group: a billet replacement for the 2021-onwards ZX-10RR that keeps the ignition lock, and with it the ability to use the bike on the road.

Key Features

  • Machined with the recess for the original ignition barrel, so a road-registered RR stays road-usable after the yoke is changed.
  • Cut from solid high-strength aluminium alloy — a billet part holds its clamping geometry in a way a casting cannot guarantee.
  • Micro shot-peened with steel balls, a surface treatment that puts the outer layer of the metal into compression and lifts its fatigue strength.
  • Black or silver anodising for corrosion and wear resistance.
  • Bonamici Racing, made in Italy. Part number PSK3.

Why an RR Owner Would Change the Yoke at All

The RR already leaves the factory with the expensive parts fitted, so the reasons for a new top clamp are not about weight. They are about handlebar position and about the clamping itself. A billet yoke lets you run the clip-ons where you want them and gives a clamping face that has been machined rather than cast, which matters when the fork tubes are being asked to work at circuit loads for twenty minutes at a time. If you are running the bike on a kit ECU and adjusting the front end between sessions, the yoke stops being cosmetic.

The Lock Is the Whole Decision

Bonamici offers this clamp in two specifications and the difference is one feature. PSK3 accepts the original ignition lock. The race version, PSK3R, does not — once it is fitted the barrel cannot be put back. For a bike that is trailered to every event that is no loss at all. For one that is ridden to them, it ends the conversation.

Fitment and Compatibility

Machined for a single machine:

  • Kawasaki ZX-10 RR — model years 2021 through 2026

The 2016-2020 ZX-10RR uses PSK1 and is not interchangeable.

Road Approval

No ABE and no EC type-approval exists for this part. Because a fork yoke carries chassis loads, German road use without a Teilegutachten is at the owner's risk and affects the operating permit. On a closed circuit the question does not arise.
