A twenty-four-hour race is a different test from a sprint — the same joints heat and cool through pit stops, rider changes and a night session, and a collector that merely survives twenty minutes is not qualified for it.\u003c\/p\u003e\u003cp\u003eThat is the case for buying an endurance-derived part for a bike that will never see Le Mans: whatever margin was engineered in for a twenty-four-hour race is margin you keep on a track day.\u003c\/p\u003e\u003ch2\u003eEWC or STEP2\u003c\/h2\u003e\u003cp\u003eSpark offers two titanium collectors on this bike at the same price, and the difference is the specification rather than the material. Both are D.65, both are titanium, both delete the catalytic converter, and both have their own 400 mm Force Evo silencer group — G00SI39T for the EWC, G00SI40T for the STEP2.\u003c\/p\u003e\u003cp\u003eThe decision you can actually make on paper is the pillion seat. Spark lists the STEP2 systems as compatible with the passenger footpegs and states that the EWC version is not. If someone rides on the back of your R1, take the GYA8880R. If the bike is a track bike with the pillion pegs already removed, the endurance configuration costs you nothing you were using.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eYamaha R1 and R1M, 2015 through 2025.
