Me too, just shy of 53,000. Had an expensive replacement when the ECU/CDI went ka-put... that was at least 25,000 miles ago now though. Had to replace starter solenoid too. Apart from that just usual stuff for me. May have to replace clutch cable soon for first time.

My old man has 80,000 on his now. He's replaced ECU/CDI and a coil. That's it, just general wear and tear parts.

The bikes electrics take a real battering riding all year round in the UK, so do the calipers!
