Constructed from hot-rolled ASTM 4115 material, these connecting rods undergo a case-hardening process to achieve a hardness of 58-62 Rc, ensuring exceptional strength and wear resistance. The innovative design incorporates side scalloping and vent slots, which are crucial for minimizing distortion in the bearing races at high RPMs.\n\nFurther enhancing its robustness, the rods are double-forged to optimize grain flow and ensure consistent dimensions. They are also shot-peened and double-honed, making them highly capable of withstanding significant loads. The small ends feature double-drilled holes to improve lubrication and cooling for the wrist pin bearing, a vital feature in high-stress environments. For superior performance and reduced friction, the included thrust washers and crank pin bearings are finished with a silver coating.\n\n### Key Features:\n\n\t\n- Complete assembly includes rod, crank pin, crank pin bearing, top-end bearing, and thrust washers.\n\t\n- Manufactured from hot-rolled ASTM 4115 material with a case-hardened finish (58-62 Rc).\n\t\n- Advanced design elements such as side scalloping and vent slots reduce high-rpm distortion.\n\t\n- Double-forged construction promotes improved grain flow and dimensional stability.\n\t\n- Shot-peened and double-honed for superior strength under heavy operational loads.\n\t\n- Double-drilled small ends enhance lubrication and cooling of the wrist pin bearing.\n\t\n- Silver-coated thrust washers and crank pin bearings offer increased lubricity.\n\n### Technical Specifications:\n\n\t\n- Big End Bearing Dimensions: 34mm x 42mm x 20mm\n\t\n- Big End Bore Diameter: 42.00mm\n\t\n- Big End Width: 19.95mm\n\t\n- Center to Center Length: 103.50mm\n\t\n- Pin Diameter: 34.00mm\n\t\n- Pin Length: 60.80mm\n\t\n- Small End Bearing Type: Bushing\n\t\n- Small End Bore Diameter: 18.00mm\n\n### OEM Part Number Cross-Reference:\n\n\t\n- YAMAHA: 5TA-11651-00-00\n\t\n- YAMAHA: 5XD-11651-00-00","weightGrams":null,"fitments":[{"make":"YAMAHA","model":"WR 450F","cc":null,"notes":null,"years":"2003–2006"},{"make":"YAMAHA","model":"WRF 450","cc":null,"notes":null,"years":"2003–2006"},{"make":"YAMAHA","model":"YZ 450F","cc":null,"notes":null,"years":"2003–2005"},{"make":"YAMAHA","model":"YZF 450","cc":null,"notes":null,"years":"2003–2005"}],"collections":[{"name":"Crankshafts & Parts","url":"https://www.2brosparts.com/api/agent/collection/GB/crankshafts-parts"},{"name":"Connecting Rod","url":"https://www.2brosparts.com/api/agent/collection/GB/connecting-rod"}],"links":{"page":"https://www.2brosparts.com/products/connecting-rod-03-05-yzf450-hot-rods-8621-yamaha-mx","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/b6f8d4f2d810:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/b6f8d4f2d810:1"}},"market":{"country":"GB","countryName":"United Kingdom","locale":"en-gb","currency":"GBP","exchangeRateFromGbp":1,"pricesIncludeUkVat":true,"checkoutTax":null,"delivery":[{"name":"Standard","description":"Orders £15.00–£59.99 · 2–4 business days","carrier":null,"estimatedDays":"2–4 business days","price":{"amount":4.99,"formatted":"£4.99"},"free":false,"minimumOrder":{"amount":0,"formatted":"£0.00","gbp":0},"weightGrams":null},{"name":"Standard","description":"Orders £60.00 and up · 2–4 business days","carrier":null,"estimatedDays":"2–4 business days","price":{"amount":0,"formatted":"£0.00"},"free":true,"minimumOrder":{"amount":60,"formatted":"£60.00","gbp":60},"weightGrams":null}],"storeUrl":"https://www.2brosparts.com"},"navigate":{"start":"https://www.2brosparts.com/api/agent","search":"https://www.2brosparts.com/api/agent/search/GB/{words+joined+with+plus}"},"howToBuy":{"summary":"Build a basket for the shopper and give them one checkout link.
