I have a 1984 cb650SC I bought in 1998 and the only problem I can directly relate to age is the turns signals have a plastic or rubber like spacer between the chromed part and the mount on the motorcycle and they became brittle and all broke one summer about4 years ago, other than that as far as I know all the fuel vacuum and brake lines are original. I have put on one set of front brake pads and changed brake fluid, rear drive lube, spark plugs, and other routine maintenance. Don't used electric vests or gloves on older bikes because the stators/electrical system are not rated for them(don't ask me how I know). It is a great ride, quick, sporty and rated at 430 pounds or so dry so unlike my Goldwing you don't feel like an aircragt carrier on maneuvers.
