In practice, this means \u003cstrong\u003egreater strength at high RPM and a wider safety margin\u003c\/strong\u003e when you fit higher-performance cylinders, exhausts, or carburetors.\u003c\/p\u003e\n\u003cp\u003eThe key difference in this version is the \u003cstrong\u003e85 mm connecting rod\u003c\/strong\u003e. Being longer than the usual size, it allows for a different engine geometry and can help reduce the connecting rod working angle during the piston stroke. This reduces part of the lateral thrust on the piston and cylinder, something especially valuable in engines that operate at \u003cstrong\u003ehigh revs and with demanding builds\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eHowever, a longer connecting rod also changes the position of the piston inside the cylinder. For that reason, when fitting this crankshaft, it is necessary to \u003cstrong\u003eshim the base of the cylinder\u003c\/strong\u003e to restore the correct assembly height and leave the piston in the proper position relative to the cylinder head.\u003c\/p\u003e\n\u003cp\u003eThat adjustment is not just a matter of installation. Modifying the cylinder height also changes the \u003cstrong\u003esquish\u003c\/strong\u003e, so it is essential to measure and correct it before starting the engine. A squish that is too tight can cause the piston to contact the cylinder head, while one that is too wide can worsen combustion and reduce performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does the 85 mm connecting rod provide?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGreater connecting rod length\u003c\/strong\u003e for specific high-performance setups.\u003c\/li\u003e\n\u003cli\u003eA smaller connecting rod working angle during part of the piston stroke.\u003c\/li\u003e\n\u003cli\u003eLess lateral thrust on the \u003cstrong\u003episton and cylinder\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003eA more suitable foundation for engines operating at \u003cstrong\u003ehigh RPM\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003eMore scope for developing Racing setups with specific engine geometries.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWrist pin:\u003c\/strong\u003e 12 mm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnecting rod length:\u003c\/strong\u003e 85 mm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnecting rod type:\u003c\/strong\u003e machined.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e horizontal Minarelli.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct:\u003c\/strong\u003e crankshaft.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e this crankshaft with an 85 mm connecting rod \u003cstrong\u003emust not be installed as a direct replacement without checking the engine geometry\u003c\/strong\u003e.
