The Force Evo in titanium, 400 mm, sized for the D.60 STEP2 system — the case with the rib that converges into the carbon end cap, and the one the factory runs in the Endurance World Championship.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eForce Evo silencer group, titanium, 400 mm, for the Yamaha R1 and R1M.\u003c\/li\u003e\n\u003cli\u003eFor Spark's D.60 STEP2 manifold.\u003c\/li\u003e\n\u003cli\u003eWithin the 102 dB limit of the French championship and the Endurance World Championship.\u003c\/li\u003e\n\u003cli\u003eTitanium case with a rib running into the lines of the carbon end cap.\u003c\/li\u003e\n\u003cli\u003eThe silencer fitted to Spark's EWC full titanium system.\u003c\/li\u003e\n\u003cli\u003eTakes the G9999 dB killer as an option.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eForce or Force Evo\u003c\/h2\u003e\u003cp\u003eBoth clear the same limit, so this is not a choice about legality. The Force is Spark's long-running case: cylindrical, plain, with a straightforward mounting interface. The Force Evo is the newer design — a ribbed titanium sleeve closed by a carbon end cap, with the rib carried into the end cap's lines.\u003c\/p\u003e\u003cp\u003eAround fifty euros separates them at this length. What that buys is the appearance of the silencer Spark puts on its endurance racing bikes rather than the one it has sold for years, on a bike where the silencer is the only part of the exhaust anyone sees.\u003c\/p\u003e\u003ch2\u003eWhat a Silencer Group Contains\u003c\/h2\u003e\u003cp\u003eSpark sells these as groups rather than as bare cases: the silencer together with the parts needed to hang it on the connecting pipe. That matters when you are replacing a damaged silencer rather than building a system, because the mounting hardware is what usually gets bent in the crash that killed the silencer.\u003c\/p\u003e\u003cp\u003eA dB killer is not part of it. Spark's stated aim for this range is to meet the limits without one, and the Force Evo does at 102 dB.
