The case on its own. Spark's 400 mm titanium Force Evo silencer for the D.65 EWC system, sold without the cover group — the part number to quote when a silencer has to be replaced and everything else on the bike survived.
Key Features
- Force Evo silencer, titanium, 400 mm, for the D.65 EWC system.
- Yamaha R1 and R1M, 2015 through 2025.
- Within the 102 dB limit of the French championship and the Endurance World Championship.
- Supplied without the cover group.
- Specific to the EWC configuration — not the STEP2 part.
- Around a hundred euros less than the complete G00SI39T group.
Why the Two Specifications Are Not Interchangeable
Spark lists separate silencers for the STEP2 and EWC versions of its D.65 system at an identical price — SGCM12400025T and this one. Identical prices for different part numbers mean the same case built to a different interface, not a better or worse product.
The consequence is practical: order by the system you own, not by the description. If your R1 carries the EWC collector GYA8894R, this is the silencer. If it carries the STEP2 collector GYA8880R or GYA8881R, it is the other number. The two look alike enough that a mistake will only surface on the workbench.
The Crash Part
Silencers are consumable in a way collectors are not. A low-side takes the case, the end cap and usually the mounting hardware, while the collector — tucked under the engine — comes through untouched. Being able to buy the case alone is what keeps that a four-figure exhaust rather than a repeat purchase of one.
Check the cover before ordering. If it went down too, the G00SI39T group includes both and costs a little over a hundred euros more than this part.
Fitment & Compatibility
Yamaha R1 and R1M, 2015 through 2025, on Spark's D.65 EWC collector GYA8894R. The complete EWC system is GYA8894T. The silencer with cover group is G00SI39T. The G9999 dB killer fits the Force Evo case.
Road Approval
None. The silencer carries no EC certificate and the system it belongs to has no catalytic converter. Closed circuits only.
