Remove the reed valves and the head is left open; JP ES 042 is the machined plate that closes it.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFor the Aprilia Tuono 457, 2024 through 2026\u003c\/li\u003e\n\u003cli\u003eCNC-machined aluminium plate in place of the original PAIR cover\u003c\/li\u003e\n\u003cli\u003eSeals the cylinder head port after the reed valve is removed\u003c\/li\u003e\n\u003cli\u003eBolts to the original mounting points\u003c\/li\u003e\n\u003cli\u003eNo electrical connection — this is the mechanical part of the delete\u003c\/li\u003e\n\u003cli\u003eSame part number as the RS 457\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhat the Plate Does and Does Not Do\u003c\/h2\u003e\n\u003cp\u003eIt closes a hole. That is the whole job, and it is worth being clear about it: the plate does not stop the ECU from looking for the PAIR solenoid, and on its own it will leave a fault on the dashboard. The solenoid eliminator is the part that handles that, and the two are usually bought together.\u003c\/p\u003e\n\u003ch2\u003eVisible on a Naked Bike\u003c\/h2\u003e\n\u003cp\u003eOn the faired RS this plate is hidden behind bodywork. On the Tuono the cylinder head is largely on show, so the finish of anything bolted to it is part of how the engine looks. A machined and anodised plate reads as intentional; a flat blank does not.\u003c\/p\u003e\n\u003ch2\u003eFitting It\u003c\/h2\u003e\n\u003cp\u003eUnbolt the reed valve cover, remove the valve, clean the face, fit the plate with the original fasteners. There is nothing to time, adjust or bleed, and the engine can be started immediately afterwards — with the caveat that the dashboard will show the PAIR fault until the electrical side is dealt with.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAprilia Tuono 457 (2024–2026)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eRoad Approval\u003c\/h2\u003e\n\u003cp\u003eNone.

Clean the mating face properly before fitting: the original gasket surface usually carries a ring of baked-on residue that will hold the plate off just enough to weep once the engine is hot.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: JetPrime\u003c\/li\u003e\n\u003cli\u003ePart number: JP ES 042\u003c\/li\u003e\n\u003cli\u003eType: SLS\/AIS block-off plate\u003c\/li\u003e\n\u003cli\u003eFunction: CNC-machined cover plate replacing the original PAIR cover\u003c\/li\u003e\n\u003cli\u003eMaterial: CNC-machined aluminium\u003c\/li\u003e\n\u003cli\u003eInstallation: plug-and-play, no modification to the original wiring\u003c\/li\u003e\n\u003cli\u003eFitment: Aprilia Tuono 457 (2024–2026)\u003c\/li\u003e\n\u003cli\u003eRoad approval: none — closed-circuit and race use only\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JetPrime","offers":[{"title":"Default Title","offer_id":53627274428682,"sku":"JP ES 042","price":12900.0,"currency_code":"LKR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/14_0_dd5ca576-07ca-4f3f-ae92-f1516f7c3e14.png?v=1788520219","url":"https:\/\/inter-pace.com\/en-lk\/products\/jetprime-sls-ais-block-off-plate-aprilia-tuono-457-es-042","provider":"Inter-Pace","version":"1.0","type":"link"}
