A silencer and its cover sold as one group is a service-friendly arrangement rather than a marketing bundle — one part number, one box, everything that hangs on the connecting pipe.\u003c\/p\u003e\u003cp\u003eFor a customer that translates into fewer questions during a rebuild. If the tail of the exhaust needs replacing after a long season, this number replaces all of it in one go.\u003c\/p\u003e\u003ch2\u003eWhat EWC Costs You\u003c\/h2\u003e\u003cp\u003eSpark states that the EWC version is not compatible with the passenger footrests, and that is the one thing worth checking before committing to this half of the range. The STEP2 systems keep them; the endurance configuration does not.\u003c\/p\u003e\u003cp\u003eOn a bike that has never carried a pillion it is not a cost at all. On a road-registered R1 it is the difference between a motorcycle two people can use and one that seats a rider only — and no amount of racing pedigree makes that decision for you.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eYamaha R1 and R1M, 2015 through 2025, on Spark's D.65 EWC collector GYA8894R.
