Oh, and service intervals...


Well, mechanically nothing changed. 7500 mi v. 6000 mi is an adjustment to remove some of the perception that ducs are high maintenance. As the valves go out of spec because of stem elongation, the bike's performance drops slightly. Let it keep staying ever so slightly out of spec, and there's no harm to the motor, just that it won't feel as "tight" or "precise".

The change in intervals has been done over the years by setting the valve clearance limits to a looser spec. The range has increased. No longer does Ducati advise 0.000" closers and 0.004" openers, they have a broader range. Most of the tuners and non-factory advice-givers will still recommend those listed "old-world" specs. Not that you have to use them (and likely it would be expensive to switch over to them the first time since many shims would need changed for those precise numbers)

Anyhow, the number of valves is halved, thus the number of shims is halved. Less to look at to begin with (part of the allure of the 2v Duc engine). Additionally, most 2v Duc engines are naked or semi-naked (all but fully faired supersports). Makes getting in there miles easier. This is why I chose a Monster for my first Duc rather than a supersport (cost kept me away from a superbike. and i'll have some humble pie, also lack of experience on the road).

The new evo cases are lighter by shaving weight off the crankcases themselves. You are saving weight from areas that aren't "risky", like a tighter fit around the shift drum and such at the back of the bike. So that's the skinny on the new motors. The 1000DS has had some issues with fueling and tuning for pipes/intake, etc. Those have all been solved via aftermarket or DP ecu changes.

Can't really think of anything else this morning.


Don't know how a person changes to GP shift on the Hyper or Multi, so g'luck on that if you are used to it on the SBK.

...coulda' got a half fairing SS!
