Spark builds R6 silencers at two inlet diameters: 60 mm and 65 mm. This one is 65. The Grid-O silencer GYA8867ST is 60. Five millimetres is invisible in a listing photograph and fatal at the workbench.\u003c\/p\u003e\u003cp\u003eIf the system on the bike is a STEP 3 titanium kit, 65 is what it wants.

This article is the group — the body plus the connecting hardware, ready to bolt on. SGCM12400028T is the same 400 mm Force Evo case listed as a spare part, sixty-one euro less, without that hardware.\u003c\/p\u003e\u003cp\u003eOrder the group if the old silencer went down the road with its fittings attached. Order the spare part only if you still have the clamps, the bush and the bracket in front of you and know they are serviceable.\u003c\/p\u003e\u003ch2\u003eWhat the Evo Case Is\u003c\/h2\u003e\u003cp\u003eRibs run back along the titanium body and converge towards a racing-style carbon end cap. The ribbing stiffens the sleeve, which lets Spark keep the wall thin, and the taper is what makes a Force Evo recognisable across a paddock.\u003c\/p\u003e\u003cp\u003eIn the full STEP 3 system this case is the one Spark rates at 102 dB — the configuration built to clear the limit most European circuits publish.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eYamaha R6 and YZF-R6 Race, 2017 to 2026, on Spark's 65 mm STEP 3 systems.
