DescriptionThe whole story▼

When precision control and rider safety are non-negotiable, the Bonamici Racing rearset kit K020 delivers the engineering confidence that track and road riders demand. Designed specifically for the Kawasaki ZX-6R, 636 and RR from 2018 to 2026, this CNC-machined aluminium rearset system offers millimetre-accurate adjustability combined with a black anodised finish that resists wear and corrosion across every session.

Key Features

  • Millimetre-precise position adjustment for both the foot brake lever and gear shift pedal, allowing you to dial in an ergonomic setup that suits your exact riding style and body geometry.
  • Supports both standard and reverse (GP) shift patterns, making the K020 a genuinely versatile choice for road, track day and race use without requiring additional components.
  • Integrated return spring in the foot brake lever ensures consistent, reliable pedal return under braking — a critical safety characteristic at the limit.
  • Anti-slip footpeg surfaces retain boot grip even in wet or demanding conditions, reducing rider fatigue and improving overall control confidence.
  • Rubber-tipped gear shift pedal tip absorbs vibration and maintains positive shift feel, complementing the precision of the aluminium structure.
  • Direct bolt-on fitment — no modifications to the frame or subframe required for the ZX-6R / 636 / RR application.

Engineering and Build Quality

Every component of the K020 rearset is CNC-milled from high-grade aluminium billet, a process that guarantees dimensional accuracy and eliminates the porosity weaknesses associated with cast parts. The black anodising treatment penetrates the surface layer of the aluminium rather than sitting on top of it, providing meaningful protection against abrasion, track debris and the elements — while retaining the aggressive, purposeful aesthetic that defines Bonamici Racing's catalogue.

The return spring integrated into the brake lever arm is a detail that distinguishes a professional-grade rearset from an aftermarket approximation. Consistent spring tension means the lever returns to the same position every time, giving the rider predictable brake pedal feel and reducing the cognitive load during fast lap sequences or emergency braking on the road.

Road and Track Use

The K020 is equally at home on a Sunday morning back-road run as it is in pit lane ahead of a club race. The choice between standard and reverse shift patterns means this single kit can serve a commuter-cum-track-day rider without compromise. Adjust footpeg height and fore-aft position to match your knee angle in the corners, set the brake lever to suit your foot arch, and the Kawasaki ZX-6R transforms into a machine that feels bespoke to you — because, in practical terms, it is.
