for my 1994 Tour, over 80tkm (50tmls) wghen I sold it and it is still going strong, now only on the race track.
Still the same crank, conrod, valves, guides...
My SZR has over 50tkm with no problems and haituao revving over 8000, sometimes to 9.
I lost track of the red one.
The green one spent the better part of its life with an Odo, so I cannot say but that engine has been "tampered with" far too much to be of any interest here.
Customer's engine here on the bench with 35tkm looks like new inside; cross-scorcing of the honing stones is still strongly visible. He pushes it, tho.
Like I always say, XTZ engines are unbreakable as long as you treat them right: no low RPM under load, proper time to warm up, decent oil.
