In many series the machine is required to run a standard airbox, so tidying what sits above the head is one of the few areas where anything can be done at all.\u003c\/p\u003e\n\u003ch2\u003eHeat Cycles Are the Test\u003c\/h2\u003e\n\u003cp\u003eWhat defeats an improvised cover is not pressure but the constant expansion and contraction between a cold start and a hot head. A race bike sees that cycle several times a day, every event. Aluminium expands at a rate close to the head itself, which is why the fastener keeps its tension where a bodged plate loosens.\u003c\/p\u003e\n\u003ch2\u003eEasy Access on an Inline Four\u003c\/h2\u003e\n\u003cp\u003eThe reed valve housings sit along the top of the head, all four reachable once the airbox is out. Compared with doing the same job on a V-twin or a V4, this is straightforward — one of the reasons it is such a routine modification on this bike.\u003c\/p\u003e\n\u003ch2\u003eFitment\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eHonda CBR 600 RR (2003–2026)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eRoad Approval\u003c\/h2\u003e\n\u003cp\u003eNone.
