SOHCS:
Just a little idea for easy rear sets in that 400F. simple!
The dismantled motor was of a guy who made all the way to Adria from Czech republic only to break a cyl "bolt". Then I noticed that there were no studs, turns out that in order to be able to take the head and cyl block off, in this 650/50 hybrid he switched from studs to allen bolts that he screws into the cases form above. Havent decided if its smart or stupid.
#642 deserves BOM title, just too cute and clean with motocicliveloci body work.
#672 & # 611 were built by tuning friend Flavio Crispi form Milan, notice his smart hydraulic clutch conversion!
Last two, the Sicilian army of the Mancuso bothers from Palermo, older borther was vice champs last year in 4-str. 500. The bikes are fast, THEY are fast (younger brother in pic does also modern italian SBK) but they push them to the limit too, this time they collected 3 DNF's.... all are with 70's bimota replica bodywork.
