DescriptionThe whole story▼
Crafted in Italy from aerospace-grade titanium with a hand-finished carbon end cap, the Spark Exhaust Konix Evo is where Italian exhaust heritage meets modern superbike engineering. Designed specifically for the Aprilia RSV4/1100 Factory, RF and RR (2017-2020), this slip-on silencer strips 1.8 kg from the stock system — cutting carried weight from 3.6 kg down to just 1.8 kg — sharpening chassis dynamics and throttle response in a single swap.
Key Features
- Titanium canister construction: light, heat-resistant and built to last the lifetime of the bike
- Carbon end cap adds visual drama and structural rigidity without adding weight
- Removable DB-killer gives you 107 dB at 5,500 rpm on track or a civilised 104 dB at 5,500 rpm on the road
- 1.8 kg weight saving over the original silencer, directly improving mass centralisation and handling
- Made in Italy — every canister hand-assembled to Spark's exacting production standards
- Complete installation kit included: all exhaust springs and mounting hardware supplied
Design, Finish and Heritage
The Konix Evo carries the unmistakable aesthetic of Italian performance manufacturing. The raw titanium canister develops a distinctive heat-blued patina over time, making each silencer genuinely unique to the rider and machine it serves. The carbon fibre end cap is not a cosmetic afterthought — it reinforces the outlet under sustained high-temperature use while providing the visual contrast that sets the Konix Evo apart from lesser aftermarket options. Spark Exhaust has been producing race-bred exhausts in Italy for decades, and the GAP0405 reflects that lineage in every weld and finish detail.
Performance and Sound
Beyond the visual upgrade, the Konix Evo delivers a measurable improvement in throttle response and mid-range feel on the RSV4 platform. The freer-flowing canister reduces back-pressure across the rev range, and the 1.8 kg reduction in unsprung and carried mass translates directly into more agile direction changes — a genuine advantage on both road and circuit. The aggressive exhaust note — 107 dB open, 104 dB with the DB-killer fitted — is characterful without being anti-social. For those chasing maximum power, Spark and Inter-Pace recommend pairing this slip-on with a dedicated race map or a custom dyno session to extract the full potential of the revised exhaust flow.
