The Desmosedici Stradale engine is a 90° V4 with Desmodromic timing, just like the Desmosedici GP from
which it also takes an 81 mm bore (the maximum allowed by MotoGP rules). This has been combined with a
longer stroke than that used in racing (giving a total displacement of 1,103 cm3) to boost low-to-mid rev
torque and reduce maximum revs so that the power is easier to handle. The new Ducati engine puts out a
maximum of 214 hp at 13,000 rpm, making the Panigale V4 the most powerful bike in the segment, yet easy
to handle thanks to a torque of 12.6 Kgm at 10,000 rpm. Despite such outstanding performance, the
Desmosedici Stradale has long maintenance intervals, with valve clearance inspection only necessary every
24,000 km.

Hadn't heard of 'Desmodromic timing before so I googled and this is the result with some interesting comments.

Not a new technology. Plus side: Pretty well eliminates valve float at high rpm. Minus side: Adds a lot of high stress and precision fit components. Believe MercBenz played with this in the 50's/60's in their race cars. Pretty pricey!!
