DescriptionThe whole story▼
Built for riders who demand race-level performance from every session, the Spark Exhaust Force Evo full system is engineered specifically for the Aprilia RS 660 from 2020 through 2026. A stainless steel header paired with a titanium silencer and carbon end cap shaves 0.7 kg off the stock system, sharpen throttle response and deliver a raw, track-bred exhaust note that makes the RS 660's parallel-twin come alive.
Key Features
- Genuine weight saving of 0.7 kg over the OEM system (5.4 kg vs 6.1 kg stock) — measurable improvement to handling agility and mass centralisation.
- Stainless steel header for long-term corrosion resistance and efficient gas scavenging.
- Titanium slip-on silencer with a signature ribbed housing and seamlessly integrated carbon end cap for a purposeful, race-shop aesthetic.
- Optimised exhaust routing improves gas flow, sharpens throttle pick-up and unlocks maximum engine output.
- Removable db killer (part number G9999) included — run open on track, compliant on road.
- Full fitting kit supplied, including a dedicated pillion footpeg-compatible bracket for a clean, stress-free installation.
Force Evo Silencer Construction
The Force Evo name denotes Spark's evolved iteration of their race-proven Force silencer design. The titanium canister features a characteristic pressed rib along the body that flows visually into the carbon fibre end cap, giving the system a cohesive, competition-inspired appearance without a gram of unnecessary material. At approximately 99 dB measured at 5,500 rpm, the exhaust note is purposeful and characterful — the kind of sound that rewards hard acceleration without becoming tiresome on longer rides.
Performance & Track Use
Replacing the entire OEM exhaust path from header to silencer exit means the Force Evo is free to optimise flow at every stage, rather than simply uncorking a restriction at the can. The result is improved throttle response across the mid-range and a more linear power delivery that rewards precise corner-exit technique on circuit. For riders looking to extract the maximum from the upgrade, an ECU remap or rolling-road calibration is strongly recommended to fully exploit the improved breathing.
