Pretty much covers it right there. I would be more concerned about a 10 year old bike with 5000 miles than a 10 year old bike with 50000 miles. Gaskets dry out when bike doesn't run. Carb gets gummed up etc.
My 08 street bob has 29000 kms on the bottom end now and 7000ish on the top. Runs like a dream.
When we tore it apart to put the new jugs and heads on the cams looked pretty much new other than the center where the pushrod was riding and the stock jugs and pistons looked newish.
These twin cam engines will last 100000 miles properly maintained.
