Commonly installed in Yamaha off-road and motocross engines to compress the air-fuel mixture and transfer combustion force to the crankshaft. Maintenance teams and engine technicians use this part for repair, rebuild, and performance restoration of worn piston assemblies.\u003c\/p\u003e\n\u003ch3 data-section-id=\"plkbhx\" data-start=\"408\" data-end=\"427\"\u003eApplications:\u003c\/h3\u003e\n\u003cp data-start=\"428\" data-end=\"909\"\u003eThe Yamaha 7KA-11631-00-A0 Piston Assembly is used in Yamaha engine systems where efficient combustion and compression are critical for performance and durability. It is commonly found in Yamaha off-road motorcycles and motocross bikes, operating within the cylinder bore to convert combustion pressure into mechanical motion. This component is essential during engine rebuilds and maintenance cycles to restore compression, reduce blow-by, and maintain consistent engine output.\u003c\/p\u003e\n\u003ch3 data-section-id=\"68ulmp\" data-start=\"911\" data-end=\"942\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-start=\"943\" data-end=\"1589\"\u003e• Brand: Yamaha\u003cbr data-start=\"958\" data-end=\"961\"\u003e• Part Number: 7KA-11631-00-A0\u003cbr data-start=\"991\" data-end=\"994\"\u003e• Product Type: Piston assembly\u003cbr data-start=\"1025\" data-end=\"1028\"\u003e• Function: Compresses air-fuel mixture and transfers combustion force\u003cbr data-start=\"1098\" data-end=\"1101\"\u003e• Application: Motorcycle engine cylinder and crankshaft system\u003cbr data-start=\"1164\" data-end=\"1167\"\u003e• Fitment: Yamaha off-road motorcycles (model-specific compatibility required)\u003cbr data-start=\"1245\" data-end=\"1248\"\u003e• Material: Cast or forged aluminum alloy for high heat resistance\u003cbr data-start=\"1314\" data-end=\"1317\"\u003e• Mounting Location: Cylinder bore within engine block\u003cbr data-start=\"1371\" data-end=\"1374\"\u003e• System Role: Converts combustion energy into mechanical motion\u003cbr data-start=\"1438\" data-end=\"1441\"\u003e• Configuration: Includes piston body (rings, pin, clips typically sold separately or in kit)\u003cbr data-start=\"1534\" data-end=\"1537\"\u003e• OEM Status: Genuine Yamaha replacement component\u003c\/p\u003e\n\u003ch3 data-section-id=\"1ln9bp8\" data-start=\"1591\" data-end=\"1617\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-start=\"1618\" data-end=\"1698\"\u003e• Yamaha 7KA-11631-10-A0\u003cbr data-start=\"1642\" data-end=\"1645\"\u003e• Yamaha 5NY-11631-00-A0\u003cbr data-start=\"1669\" data-end=\"1672\"\u003e• Yamaha 3BN-11631-00-00\u003c\/p\u003e","brand":"Yamaha","offers":[{"title":"New","offer_id":51733928083758,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_6e8921cc-fefa-4535-8de5-bdd2e461bc0e.jpg?v=1770604228","url":"https:\/\/plgautomation.com\/products\/yamaha-7ka-11631-00-a0-piston-assembly","provider":"PLG Automation ","version":"1.0","type":"link"}
