This bike has a servo brake system that is prone to failure in old age. Very expensive to repair, many just bypass the abs (02-and on in this series). It also has an O-ring seal that is between the engine case and the clutch housing that fails and oils up the clutch, very expensive to repair. If your a mechanic your good. It is a heavy bike. Is this what your are looking for? All the rubber bits are old and crumbling, will need replacing, including brake lines and ignition wires. Probably the engine breather hose too. The list is long with the down side of things. With this in mind even 2500$ looks expensive to me.
