Tough old four with slightly dubious main bearings if oil changes neglected but can run to 100k when both engine and chassis rot stops it dead – wiring loom rots, tank rusts, top end breaks, etc! Early Z’s had quick wear s/a bearings, later models had needle rollers. Use Metz or Pirelli tyres and Dunlopads. Custom version, better finish, handling naff. Try to avoid anything with more than 75k on the clock. Still some nice ones.
