It is intended to work together with the \u003cstrong\u003e115LMR cylinder\u003c\/strong\u003e and \u003cstrong\u003eMetrakit crankcases\u003c\/strong\u003e, providing the solid foundation needed for a build of this calibre.\u003c\/p\u003e\n\u003cp\u003eBy increasing the stroke to \u003cstrong\u003e52 millimetres\u003c\/strong\u003e, the engine gains real displacement and allows the \u003cstrong\u003eengine to rev higher\u003c\/strong\u003e across the entire RPM range. It is necessary to replace the stock crankshaft with this model when installing large bore kits, as the original component would not withstand the inertia or mechanical stress, eventually leading to failure. Thanks to its \u003cstrong\u003especific balancing\u003c\/strong\u003e, vibrations at high RPM are reduced, allowing the engine to run more smoothly and with greater reliability.\u003c\/p\u003e\n\u003cp\u003eThe construction stands out for its \u003cstrong\u003e85 millimetre\u003c\/strong\u003e diameter flywheels, which provide optimised inertia to maintain speed. In addition, it features a \u003cstrong\u003e105 millimetre\u003c\/strong\u003e long connecting rod and a \u003cstrong\u003e20 millimetre\u003c\/strong\u003e crankpin, oversized dimensions to withstand the force of a 115cc explosion without flexing or compromising the bearings, ensuring the \u003cstrong\u003emotorcycle increases RPM\u003c\/strong\u003e with complete safety.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStroke:\u003c\/strong\u003e 52 millimetres\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnecting rod length:\u003c\/strong\u003e 105 millimetres\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlywheel diameter:\u003c\/strong\u003e 85 millimetres\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrankpin diameter:\u003c\/strong\u003e 20 millimetres\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Metrakit crankcases and 115LMR cylinder\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\u003eEuro 3 2006-2017\u003c\/li\u003e\n\u003cli\u003eEuro 4 2018-2020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TXT Exhaust","offers":[{"title":"Default Title","offer_id":55523111174529,"sku":"TXT-MOT-CIG52","price":571.36,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0860\/6223\/5959\/files\/TXT-MOT-CIG52.webp?v=1776091851","url":"https:\/\/motoscoot.net\/en\/products\/txt-exhaust-crankshaft-c-52mm-derbi-euro-3-4","provider":"Motoscoot","version":"1.0","type":"link"}
