Arrow Indy-Race Slip-On Silencer – Aluminium Dark – Kawasaki ZX-10R/RR (2021-2026) 71928AKN

The Arrow Indy-Race 71928AKN brings the aesthetic language of Arrow's racing heritage directly to the Kawasaki ZX-10R and ZX-10RR, pairing a darkened aluminium canister with a carbon end cap for a finish that reads as purposefully aggressive without sacrificing road legality. Developed specifically for the 2021-2026 ZX-10R and ZX-10RR, it delivers a measurable improvement in throttle response and a genuine step in mid-range performance, all from a unit weighing just 2.12 kg.

Key Features

• Dark-finish aluminium canister with carbon end cap — a visual signature that complements the ZX-10R's sharp bodywork without the weight penalty of steel
• Stainless steel internals for outstanding thermal durability and long service life, paired with a titanium mid-pipe for consistent heat resistance
• Weighs only 2.12 kg, contributing to improved handling balance and reduced unsprung mass over the stock unit
• E-number type approval included — fully street-legal for daily road use across Europe straight from the box
• DB killer supplied as standard, allowing volume management for road riding or removal for unrestricted track sessions
• Designed to integrate with Arrow headers and other Arrow slip-ons to build a complete performance exhaust system

Design, Finish and Heritage

Arrow has built its reputation on the race circuits of MotoGP, World Superbike and the Italian national championships. The Indy-Race line draws directly on that pedigree, translating the proportions and material choices of Arrow's competition canisters into a road-homologated package. The Dark finish — a controlled anodising process applied to the aluminium shell — gives the 71928AKN a low-key, almost industrial character that sets it apart from polished or raw-aluminium siblings in the range. Paired with the carbon end cap, the result is a cohesive, premium look that ages well and resists the discolouration that affects lesser finishes under heat cycling.

Performance and Construction

The canister measures 220 mm in length with a 60 mm inlet diameter and a 58 mm outlet diameter — dimensions Arrow has arrived at through extensive flow-bench and on-bike development with the ZX-10R platform. The aluminium outer shell keeps mass to a minimum, while the stainless steel interior components handle the extreme thermal and acoustic demands of a high-revving inline-four. The titanium mid-pipe adds another layer of heat tolerance and corrosion resistance throughout the service life of the system. Throttle response sharpens noticeably across the mid-range, and the Indy-Race delivers a characteristic Arrow soundtrack — full and purposeful at road speeds, borderline spectacular with the DB killer removed on track.

For best results, Arrow recommends a dedicated ECU remap or fuel module calibrated for the open exhaust. This ensures the engine management fully capitalises on the improved exhaust flow and avoids any lean running at partial throttle.

Fitment and Compatibility

This slip-on is developed and approved exclusively for the following motorcycles:

• Kawasaki ZX-10R — model years 2021, 2022, 2023, 2024, 2025, 2026
• Kawasaki ZX-10RR — model years 2021, 2022, 2023, 2024, 2025, 2026

The 71928AKN mounts directly to the factory header without modification. It can also be combined with an Arrow header and further Arrow slip-on units to form a full Arrow exhaust system for additional performance gains.
