Regarding the rear hub, I obtained it quite a few years ago from Disco Volanti Motorcycles here in the UK who in turm obtained it direct from the manufacturer Menani in Italy. I have a suspicion though that these hubs are no longer made, but I could be wrong. I've just tried to look for one at M3 Racing but the web site appears to have expired. Anybody know why? I do know that Paul McGhie had an original Honda one for sale a few years ago, but I don't know if he still has it. I could ask if you wish.
