86000 miles on mine, bought it new in November 2003 with 1 mile on the clock. Still sounding sweet
Only major problem was the sprocket nut which was finally resolved by my own fix. (documented in the downloads section).
Connector on the main wire to the ignition corroded from arcing and burned out and the side stand switch stopped working recently.
Replaced the connector and cleaned up the internals of the side stand switch.
Connector took 30 minutes to replace
and side stand switch took 2 hours to take off clean and put back on.
No engine out just a little ingenuity
New Motad down pipes at 84000 miles a year ago.
Only other changes were hyperpro fork springs and Hagon rear shock
Not used as often as it was, since there are 2 other bikes in the garage.
Fazer 1000 has 48000 km (6000km when bought by my son in 2010) and Serow has 34000 km (21000Km when I bought int in 2011)
