as someone who owned and raced a 750 bevel twin (and owned a 350 single), i can tell you that the newer bikes are - to me - better in almost every way. they're faster, more reliable, hold their own better against the japanese bikes and have carved out a market niche. there are more models and the pace of innovation seems much faster. now, i will grant you that none are quite as sexy as a 750 sport or a 750ss, and that by going belt rather than bevel you lose something (if only the opportunity to put a sight glass on the top bevel gear casing) but i think the newer bikes are awesome. like, wicked awesome. there are a whole bunch of them i'd like to own. and, having worked on the neanderthal electrical system of a 1973 750 (ok, having NOT worked on it), i think there will be a lot fewer WHAT THE F*** moments with the new bikes.
i'd like to see leica do something similar. move the design forward while not losing touch with the past. you can't run the company on carburated bevel twins forever, and you can't rely on black MPs to make your business forever.
also, it's interesting to note that the old ducatis were really not great race bikes. they had a very slow steering setup and were a pain in the ass to move around. the new ones are as quick to steer as any japanese bike and have kept a lot of the v-twin advantages. this would be like, for example, having an OVF/EVF hybrid on an m10. the new sets of owners made a bet to appeal to performance, raised prices and created a great market for themselves.
private equity is hardly prince charming on a white horse, but in some cases it does work out. i'd like this to be a rejuvenator for leica.
