I have one ace that just rolled over 100,000kms, It killed one battery since 97 and needed new clutch parts at 80,000. The rear shock went twice and the major chasis bearings were replaced at50,000. I´m looking at replacing alternator brushes this winter. It runs smooth and stronger than ever, recently dynoed at 125 at the back tire. The second ace is the race bike with 70,000km on the clock and has given me less problems.
