Each combustion stroke transmits the force from the piston to the \u003cstrong\u003econnecting rod and crankshaft\u003c\/strong\u003e, and the more the RPM, compression, and power increase, the greater the inertia loads borne by the entire assembly.\u003c\/p\u003e\n\u003cp\u003ePolini uses a \u003cstrong\u003ereinforced connecting rod\u003c\/strong\u003e and a 10 mm piston pin, maintaining the size used in numerous original Minarelli Vertical configurations. The assembly is supplied with the \u003cstrong\u003eneedle bearing suitable for the 10 mm pin\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eIn addition, the crankshaft is \u003cstrong\u003ebalanced to reduce vibrations and mechanical losses\u003c\/strong\u003e and receives a heat treatment intended to increase its strength. In a high-revving engine, proper balancing not only improves operation: it also reduces the stresses transmitted to bearings and crankcases.\u003c\/p\u003e\n\u003cp\u003ePolini specifies this crankshaft for setups with \u003cstrong\u003e50cc and 70cc cylinders\u003c\/strong\u003e, making it a good foundation for tuned Minarelli Vertical engines where the original crankshaft is starting to become a weak point.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003e10 mm pin\u003c\/strong\u003e makes it possible to maintain compatibility with pistons designed for this size, making it an especially interesting option for both original-configuration engines and Sport builds.\u003c\/p\u003e\n\u003cp\u003eDuring installation, we also recommend replacing the \u003cstrong\u003ecrankshaft bearings and seals\u003c\/strong\u003e and properly checking the axial play and the alignment of the assembly. In a tuned engine, reusing worn bearings can quickly compromise a new crankshaft.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical characteristics\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Polini.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRange:\u003c\/strong\u003e For Race.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReference:\u003c\/strong\u003e 210.0049.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine:\u003c\/strong\u003e Minarelli Vertical 50 2-Stroke.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine families:\u003c\/strong\u003e CY \/ MY \/ CW.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePiston pin:\u003c\/strong\u003e 10 mm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStroke:\u003c\/strong\u003e original.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnecting rod:\u003c\/strong\u003e reinforced.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBalancing:\u003c\/strong\u003e specific to reduce vibrations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTreatment:\u003c\/strong\u003e heat treatment to increase strength.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeedle bearing:\u003c\/strong\u003e included for 10 mm pin.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended application:\u003c\/strong\u003e 50cc \/ 70cc cylinders.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturing:\u003c\/strong\u003e Made in Italy.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCompatible engines\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMinarelli Vertical 50 2-Stroke CY\u003c\/li\u003e\n\u003cli\u003eMinarelli Vertical 50 2-Stroke MY\u003c\/li\u003e\n\u003cli\u003eMinarelli Vertical 50 2-Stroke CW\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Polini Motori s.p.a.","offers":[{"title":"Default Title","offer_id":67881237381511,"sku":"210.0083","price":139.39,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0860\/6223\/5959\/files\/210.0083-12.webp?v=1793790308","url":"https:\/\/motoscoot.net\/en\/products\/crankshaft-polini-minarelli-vertical-10mm-pin","provider":"Motoscoot","version":"1.0","type":"link"}
