{"product_id":"kit-admision-derbi-variant-carburador-24mm-metrakit","title":"Derbi Variant intake kit Carburettor 24mm Metrakit ","description":"\u003cp\u003eIf you notice that your \u003cstrong\u003eDerbi Variant\u003c\/strong\u003e is lacking that final push or that the engine falls short when you demand more, the problem is usually in the intake. The stock system greatly limits the \u003cstrong\u003eair and fuel flow\u003c\/strong\u003e, preventing \u003cstrong\u003ehigh-displacement\u003c\/strong\u003e cylinders from breathing as they should to deliver their full \u003cstrong\u003epower\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eWith this \u003cstrong\u003eMetrakit intake kit\u003c\/strong\u003e, we install a \u003cstrong\u003ereed valve spacer\u003c\/strong\u003e made from high-strength \u003cstrong\u003e7075 aluminium\u003c\/strong\u003e. Its \u003cstrong\u003eultra-short\u003c\/strong\u003e structure positions the reeds very close to the \u003cstrong\u003ecrankcase\u003c\/strong\u003e, which drastically improves \u003cstrong\u003epre-compression\u003c\/strong\u003e and the intake angle of the mixture. This results in a much more aggressive \u003cstrong\u003ecrankcase filling\u003c\/strong\u003e, making the bike \u003cstrong\u003erev up\u003c\/strong\u003e with immediate \u003cstrong\u003etorque\u003c\/strong\u003e from low RPM. In addition, its precision machining allows you to keep the \u003cstrong\u003eoriginal engine mounting shaft\u003c\/strong\u003e without complications.\u003c\/p\u003e\n\u003cp\u003eThe heart of the kit is the \u003cstrong\u003eMetrakit V4X reed valve\u003c\/strong\u003e, developed by \u003cstrong\u003eMoto Tassinari\u003c\/strong\u003e. By using a \u003cstrong\u003edouble prism system\u003c\/strong\u003e with \u003cstrong\u003e4 carbon petals\u003c\/strong\u003e, the opening surface is twice that of a conventional reed valve. This allows the \u003cstrong\u003eengine to rev higher\u003c\/strong\u003e at high RPM and gives \u003cstrong\u003einstant throttle response\u003c\/strong\u003e, as carbon reacts much faster than standard metal or fibre reeds. The \u003cstrong\u003emachined aluminium intake manifold\u003c\/strong\u003e together with its \u003cstrong\u003erubber connector\u003c\/strong\u003e ensure that the \u003cstrong\u003eMRDII 24mm carburettor\u003c\/strong\u003e sits at the exact angle, avoiding turbulence and ensuring a constant flow to the cylinder.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpacer material:\u003c\/strong\u003e CNC machined 7075 aluminium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReed valve:\u003c\/strong\u003e V4X by Moto Tassinari (4 petals)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReed material:\u003c\/strong\u003e Carbon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector diameter:\u003c\/strong\u003e 35 millimetres\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCarburettor compatibility:\u003c\/strong\u003e MRDII 24mm and 28mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine compatibility:\u003c\/strong\u003e Start, Start 3 and Start 5 crankcases\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eThe kit includes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReed valve spacer\u003c\/strong\u003e in 7075 aluminium\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eMetrakit V4X reed valve\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntake manifold\u003c\/strong\u003e in machined aluminium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRubber connector\u003c\/strong\u003e specific for MRDII carburettors\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eMRDII 24mm carburettor\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-pressure gasket set\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSteel bolts\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCompatible models\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDERBI\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eVARIANT START\u003c\/li\u003e\n\u003cli\u003eVARIANT START 3\u003c\/li\u003e\n\u003cli\u003eVARIANT START 5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Metrakit","offers":[{"title":"Default Title","offer_id":55539511329153,"sku":"911D1140","price":269.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0860\/6223\/5959\/files\/911D1140.webp?v=1777039345","url":"https:\/\/motoscoot.net\/en\/products\/derbi-variant-intake-kit-carburettor-24mm-metrakit","provider":"Motoscoot","version":"1.0","type":"link"}
