DescriptionThe whole story▼
Spark describes this one in a single sentence: the same kit that won the WSSP300 class in 2024. Full titanium collector, Force Evo silencer, carbon cover — the 2024 evolution of a programme that has been running on this motorcycle since 2018.
Key Features
- Full titanium racing system for the Yamaha R3 and YZF-R3.
- 2024 evolution: titanium collector, Ø60 mm, with a Force Evo titanium silencer.
- Carbon fibre cover on the silencer.
- The kit that took the WSSP300 class win in 2024.
- dB killer included.
- 2019 model year needs a specific bracket to keep the original footpegs.
The 2024 Evolution
Spark's R3 system has been developed continuously rather than launched once. The first version came out of Luca Bernardi's 2018 Italian SSP300 title, further work followed on Team Machado's WSSP300 machines and with Team MMR in CIV 2020, and this is where that line stands now.
What changed for 2024 is the silencer. The Konix builds use a wedge-shaped case; this one carries the Force Evo, the ribbed titanium case with a carbon cover, and it is the combination Spark's own description ties to the 2024 WSSP300 class win.
A Claim Spark Makes Itself
Manufacturers are usually careful with race claims. Spark is not being careful here — the Italian product note says plainly that this is the same kit that won in WSSP300 in 2024, not a replica of it and not inspired by it.
On a class where the machines are close to standard and the exhaust is one of the few free components, that is worth more than it would be in a prototype series.
Carbon Cover
The Force Evo case comes with a carbon fibre cover, which is a heat shield first and a styling item second. On a 321 cc racer with the silencer tucked under the tail unit, keeping heat away from the bodywork is not optional.
What Spark Does Not Publish
There is no weight figure and no decibel figure for this specific kit on Spark's page. The measured numbers Spark gives for this platform — 102, 104, 107 and 112 dB — belong to the Force 300 mm, the Force 300 mm Ø60, the Konix and the MotoGP respectively, and the Force Evo is a different silencer from all four.
So we quote none of them here. What is documented is the material, the construction and the race result.
A Note for 2019 Machines
Spark specifies a particular bracket on the 2019 model year if the original footpegs are to be kept, and lists this kit among those it applies to. Give us the model year with the order and we will arrange it.
Fitment & Compatibility
Yamaha R3 and YZF-R3, 2015 onwards — Spark's own model list runs to 2024, the price list to 2026. The Konix builds of the same platform are GYA8833T in full titanium and GYA8856T with a stainless collector.
Road Approval
None. Spark lists this system as not approved; it is built for closed-circuit use and must not be fitted to a motorcycle ridden on public roads.
