Take the brilliant chassis that underpins the Ducati 848, add a smaller version of the Testastretta engine from the Diavel and heaps of killer styling. What you end up with is the new Ducati 848 StreetFighter that was unveiled recently. Ducati decided to downsize the engine from the Diavel instead of just modifying the 848 mill for more low end torque.
The main advantage of this kind of a setup is that the motor won't be as temperamental as a reworked replica-racer engine. It might also carry the Diavel’s 24,000 km valve clearance intervals and such.
Technical specifications have not yet been released, but proportionally calculating the power output (yeah, yeah, we know this is not how it works) leads to a figure of about 130hp which should be great considering the spread of torque you get with that engine!
