DescriptionThe whole story

Engineered exclusively for track use, the Termignoni GP2R-R slip-on kit transforms the Kawasaki ZX-10 R/RR (2021-2026) into a sharper, more responsive machine. Built around a stainless steel silencer and a matching stainless steel link pipe, this kit delivers optimised throttle response and a race-tuned exhaust note that the stock system simply cannot match.

Part numbers, current Termignoni 2025 price list: K089094SO03 is the complete kit — GP2R-R slip-on silencer and the matching link pipe under a single part number, nothing else required. SO0309440III is the silencer on its own; it still needs link pipe K08909430I, which is not included and is ordered separately. Both options are designed exclusively for closed-circuit racing on the Kawasaki ZX-10 R/RR and are not approved for road use.

Key Features

  • Full stainless steel construction throughout — both the GP2R-R silencer and the link pipe resist corrosion and withstand sustained high-heat race conditions.
  • Optimised exhaust flow via the dedicated link pipe K08909430I, contributing to improved throttle response and overall track performance.
  • DB Killer included — gives you adjustable sound output to meet circuit noise regulations without compromising the exhaust character.
  • Available as a complete kit (silencer + link pipe) or as the slip-on silencer alone, giving you flexibility to build around parts you already hold.
  • Race use only — designed without road-homologation hardware, keeping the system light and fully focused on circuit performance.

Build Quality and Performance

Termignoni has long been the name behind factory-level exhaust systems on WorldSBK machinery, and the GP2R-R carries that pedigree directly to club and endurance racers. The stainless steel silencer (part number SO0309440III) is constructed to handle the thermal and mechanical loads of back-to-back track sessions, resisting heat discolouration and fatigue far better than OEM-grade mild steel alternatives. The link pipe (K08909430I) is engineered to pair precisely with the silencer, ensuring gas flow is uninterrupted from the header collector to the outlet — a pairing that produces the throttle response improvements Termignoni's engineers designed the system around.

Track Suitability and Important Notes

This kit is intended purely for closed-circuit competition use. It does not carry road-use homologation and must not be fitted to any motorcycle operated on public roads.

Fitment and Compatibility

The Termignoni GP2R-R slip-on kit is a direct-fit replacement for the Kawasaki ZX-10 R and ZX-10 RR covering model years 2021 through 2026. No additional brackets or adaptors are required when used with the specified link pipe.
