More recent examples last longer than earlier bikes but frequent oil changes are essential for engine longevity (30-50k; neglected bikes took out the camshaft at 12k). Top end and big-end noises should be viewed with fear. Vibes at 5500 revs normal but should smooth out thereafter. Uni-track and disc wear. Engine needs spark plugs every 5k. Some bargains out there.
