Sorry to hear you didn't keep the Harley. Perhaps you will give them another go one day. Have to admit mine, which I've owned since '06 has been no trouble at all and I do about 4000 miles per year. Engine is solid mounted in frame and I find the twin balancer shafts do a good job of keeping vibration levels down, though I rarely ride the machine above 75mph. Also perhaps drier climate in S.France makes ownership easier!
Cheers
