At the heart of the new Diavel is the Testastretta 11 engine that originally appeared in the ground-breaking Multistrada 1200. But is that enough to outgun the Yamaha V-Max?
Yes. The Testastretta 11 has a redesigned cylinder head and cam timing to produce softer power than the original superbike engine on which it’s based – the 11 referring to the angle of valve overlap which has been reduced from the 1198’s 41.
Besides the headline top-end figure of 162bhp, Ducati claim that revised intake and exhaust ports combined with radical adjustment of the cam timing produce strong low rpm torque.
Though Yamaha’s 1600cc V-Max produces significantly more power – making close to 200bhp – it is much heavier, weighing in at 310kg. That’s 103kg heavier than the Ducati.
This means the V-Max’s power-to-weight ratio (0.63bhp per kg) is lower than the Ducati’s (0.78bhp per kg).
