Melotti Racing's aluminium AIS Valve Cover closes the gap that leaves on the YZF-R3's cylinder head, built specifically for this engine.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAIS valve cover for the Yamaha YZF-R3, 2015 to 2020\u003c\/li\u003e\n\u003cli\u003eMelotti part AIS.YA.1151\u003c\/li\u003e\n\u003cli\u003eAluminium construction for track bikes removing the AIS system\u003c\/li\u003e\n\u003cli\u003eFits without removing the reed valves, reusing their existing gasket\u003c\/li\u003e\n\u003cli\u003eRubber plug included to seal the air-box opening\u003c\/li\u003e\n\u003cli\u003eSame part also listed for the Yamaha YZF-R25\u003c\/li\u003e\n\u003cli\u003eBlack finish\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eConstruction and Material Quality\u003c\/h2\u003e\n\u003cp\u003eMelotti machines the AIS.YA.1151 in aluminium, shaped to seal exactly the hole a YZF-R3 is left with once its AIS lines and valve are stripped out for track use. It is built so the reed valves behind it never have to be disturbed: the existing gasket under them stays in place and seals the new cover too, which saves a part and a step compared with covers that demand a fresh gasket. A rubber plug supplied in the kit closes the matching hole in the air box, keeping the induction tract sealed once the AIS hardware itself is gone.\u003c\/p\u003e\n\u003ch2\u003eA Small Bike's First Race Build\u003c\/h2\u003e\n\u003cp\u003eA YZF-R3 bound for a lightweight or novice class usually goes through a short, well-worn list of changes before its first scrutineering, and removing the AIS system sits near the top of that list for most series. Melotti built this cover around how that job is actually done in a home garage or a small team's van: no new gasket to source, no extra machining, just the cover and the supplied plug replacing hardware that has already come off. It is one of the cheaper items on a first-season build sheet, but it is also one that almost every raced YZF-R3 ends up wearing before its first flag drops.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cp\u003eMelotti lists the AIS.YA.1151 for the Yamaha YZF-R3 built between 2015 and 2020, and our listing follows that range. The identical part is also catalogued in our shop for the Yamaha YZF-R25 of the same years, since both engines share the same AIS layout. It pairs naturally with Melotti's brake reservoir guard and Öhlins shock reservoir guard, also listed for the YZF-R3.\u003c\/p\u003e\n\u003ch2\u003eRoad Approval\u003c\/h2\u003e\n\u003cp\u003eWe hold no ABE for the AIS.YA.1151, and a bike with its AIS system removed is not something that can be registered for road use in that state.
