Bonamici Racing Top Yoke Street – Kawasaki ZX-10 R / ZX-10 RR (2016-2020) PSK1

The Bonamici Racing PSK1 street top yoke is a precision-engineered replacement upper fork bridge for the Kawasaki ZX-10 R and ZX-10 RR (2016–2020), designed to sharpen steering response and improve chassis stability on the road. Machined in Italy from high-tensile aluminium and offered in anodised black or anodised silver, it is a direct-fit upgrade that installs without modification and includes preparation for the ignition key block as standard.

Key Features

• High-tensile aluminium construction delivers a robust, lightweight platform that resists flex and maintains consistent geometry under hard cornering loads.
• Street-tuned geometry optimises steering precision and front-end feel for road riding, striking the ideal balance between agility and straight-line stability.
• Pre-machined ignition key block recess simplifies installation and retains full factory switchgear compatibility — no drilling or adaptation required.
• Direct OEM-replacement fitment: no frame modifications, no adapter brackets, and no compromise to the bike's safety-critical steering assembly.
• Available in anodised black or anodised silver finishes, both applied to a high standard that resists corrosion and complements the ZX-10 R / ZX-10 RR bodywork.
• 100% Made in Italy — produced at the Bonamici Racing facility under the same quality controls applied to their motorsport components.

Build Quality and Design

Bonamici Racing manufactures the PSK1 from high-tensile aluminium using CNC machining processes that hold tight tolerances throughout the fork leg clamp bores and steering stem interface. The result is a yoke that seats squarely on the forks without shimming or reworking, preserving the precise caster and trail figures that Kawasaki engineered into the ZX-10 R platform. The hard anodised finish adds a layer of surface hardness that stands up to weather, road grime, and the inevitable knocks of everyday use far better than a painted or bare-metal surface would.

Street Application

Unlike track-only geometry parts that sacrifice road manners for outright lap-time, the PSK1 street version is calibrated for public road riding. The steering geometry promotes confidence at both low-speed urban speeds and the higher pace of sweeping A-roads, giving the rider a direct, communicative connection to the front wheel without demanding the constant physical input that aggressive race geometry can impose over a long ride.

Fitment and Compatibility

The Bonamici Racing PSK1 top yoke is a confirmed direct fit for the following models:

• Kawasaki ZX-10 R (2016, 2017, 2018, 2019, 2020)
• Kawasaki ZX-10 RR (2016, 2017, 2018, 2019, 2020)

The component mounts without any modification to the frame or existing steering assembly. The pre-machined key block preparation retains the standard ignition location.
