From the Parts Catalogue, it appears there are 6 lobes.

Also appears to be plain bearing cams like the DS1k.

Never had my hands on a DesmoTre, so I'm depending on Ducati's info....

putting 6 lobes for 3 valves blows my mind.

i guess it is cnc nowadays so who cares, but sheesh..  seems they could have designed a single rocker/lobe setup.

"Yelling out of cars, turning your speakers out the window to blast your music onto the street, setting off M-80 firecrackers, firing automatic weapons into the airâ€"these are all well and good. But none of them create a merry atmosphere of insouciance and bonhomie quite like a revving motorcycle.

Speeddog is correct. I still have mine apart doing the valves.
It's much easier than a 4V. same as a 2V just one more due to the single cam.
Plus the cover gaskets are reusable for some reason.

IIRC, the ST3 head has the same bolt pattern as the DS1000 motor (same bore and stroke too)
