Spark Exhaust Full System Titanium Kawasaki ZX-10 R/RR (2021-2026) GKA8849T

A full titanium exhaust system that shaves 4 kg from your Kawasaki ZX-10 R/RR and transforms its throttle response — without demanding a track day to justify the upgrade. The Spark GKA8849T is equally rewarding on a Sunday morning road ride as it is on circuit, thanks to the removable DB-Killer that lets you dial the sound to suit the moment.

Key Features

• Dramatic 4 kg weight reduction — from 7.8 kg down to just 3.8 kg — sharpening chassis dynamics and reducing unsprung mass for noticeably more agile handling.
• Full titanium construction throughout: header (d.65), collector and Force Evo slip-on silencer (350 mm) deliver outstanding heat resistance and long-term durability.
• Titanium end cap adds structural rigidity while keeping the overall look purposeful and race-inspired.
• Removable DB-Killer measures approximately 104 dB at 5,500 rpm when fitted — remove it for unrestricted track use whenever needed.
• Supplied with a complete fitting kit including the bracket for mounting the silencer directly to the original rear frame — no fabrication required.
• Compatible with original fairings and both standard and kit radiators, making installation straightforward for home mechanics and professional workshops alike.
• Handcrafted in Italy — Spark's hallmark attention to weld quality, fitment tolerances and finish sets this system apart from mass-produced alternatives.

Build Quality and Everyday Usability

Titanium is the engineering choice for riders who want the benefits of reduced weight without sacrificing service life. The header pipe, specified at 65 mm diameter, is TIG-welded to Spark's usual exacting standard and resists the discolouration and heat fatigue that afflict stainless or mild-steel systems over time. On the road, the removable DB-Killer keeps the system socially acceptable — and road-legal in many markets — while still delivering the characteristic Spark exhaust note that rewards hard acceleration.

The 350 mm Force Evo silencer is sized to tuck neatly within the ZX-10 R/RR's bodywork envelope, preserving the bike's clean lines. The full mounting kit included in the box means you are not hunting for hardware; Spark supplies every bracket, spring and fastener needed to complete the installation in a single session.

Performance and Track Use

Removing 4 kg from the exhaust system has a disproportionate effect on how a superbike feels: less rotational and unsprung mass translates into faster steering, improved braking stability and a livelier throttle. Spark's full system — rather than a slip-on alone — maximises the header scavenging effect and optimises mid-range torque delivery across the ZX-10 R/RR's rev range. For maximum power gains, pairing the system with a dedicated race mapping or a dyno session is recommended to allow the engine management to fully exploit the improved gas flow.

Fitment and Compatibility

This system is engineered specifically for the following models:

• Kawasaki ZX-10 R (2021, 2022, 2023, 2024, 2025, 2026)
• Kawasaki ZX-10 RR (2021, 2022, 2023, 2024, 2025, 2026)

Compatible with original fairings and both standard and aftermarket kit radiators. The supplied bracket mounts directly to the stock rear frame — no modification needed.
