LighTech Track-Use Rearsets Kawasaki ZX-4 RR (2023-2025) FTRKA014

If your Kawasaki ZX-4 RR sees regular track days, the LighTech FTRKA014 rearset system is the straightforward upgrade that delivers genuine racing ergonomics without unnecessary complexity. Developed in collaboration with MotoGP, Moto2, WSBK and WSSP teams, it brings competition-grade control to your ZX-4 RR for the 2023–2025 model years.

Key Features

• CNC-machined from Ergal 7075-T6 aluminium throughout — lightweight, rigid and highly resistant to fatigue under repeated track use
• Levers pivoted directly on the footpeg for the most direct, tactile shift and brake feel possible
• Oversized bearings on all pivot points maintain smooth, precise lever action even under sustained hard use
• Ergonomic heel guards keep your boots located securely on the pegs through fast direction changes and heavy braking zones
• Compatible with GP-shift (reverse shift pattern) — note that the shift load cell (Reload Cell) must be reconfigured when using reverse shift
• A direct bolt-on fitment for the ZX-4 RR, making it an accessible track-day upgrade whether you are a seasoned club racer or an enthusiastic newcomer to circuit riding

Built for the Track, Engineered by Racing

LighTech's rearset programme draws on decades of involvement at the highest levels of road racing. The FTRKA014 is the product of that experience distilled into a system sized for the ZX-4 RR's inline-four platform. Every component is machined in-house from Ergal 7075-T6, the same high-strength aluminium alloy used in aerospace and motorsport applications. The result is a rearset that weighs noticeably less than the standard assembly while being considerably stiffer where it matters.

The decision to pivot the brake and gear-change levers directly on the footpeg — rather than on a separate sub-bracket — reduces the number of flex points in the system and shortens the mechanical path between your input and the component being actuated. Pair that with the oversized bearings and you have a setup that feels immediate and consistent lap after lap.

Practical Trackday Value

Not every track-day rider needs a full bespoke race build, but every track-day rider benefits from controls that are properly positioned and mechanically precise. The FTRKA014 strikes that balance well: it is a complete, ready-to-fit system that requires no fabrication or specialist knowledge to install, yet it is built to the same standard as components seen in professional paddocks. For riders who use their ZX-4 RR primarily on track but want a dependable, repeatable upgrade rather than an exotic one-off, this rearset represents excellent value.

Important Safety Notice

The LighTech FTRKA014 rearset system is designed exclusively for closed-circuit track use. It is not TÜV-certified and is not approved for use on public roads. When fitting the system with a GP-shift (reverse shift) configuration, the shift load cell (Reload Cell) must be reconfigured accordingly before use.
