My parts bike had 180,000 miles (close to 300,000 kilometers). It was running well, but the transmission was shot and PO said head could not be rebuilt again. It had gone through a few final drives. On disassembly, I found a torched bearing deep in the block and that oil/coolant had mixed. Otherwise, there were still lots of useable parts.
My keeper bike has only about 45,000 miles, but it's fun to know that many parts have almost 4 times the mileage.
