Who put the “X” in the Diavel’s name and why? Because “X” might mean X Factor, it might mean “Generation X,” or it might mean you’ll soon have an “Ex” if you buy this thing. In any event, you’ll always remember your XDiavel for its stripped-down bobber look and enlarged 1,262cc Testastretta DVT V-twin engine, which is tuned for prodigious low-end torque but which still sings right up to a 9,500-rpm power peak. Visually, the XDiavel also distinguishes itself from the older Diavel by its stubby seat, shorty pipes, and speed-shop-like matte finishes. And dynamically, compared to the standard-issue Diavel, the XDiavel also has launch control and sophisticated Bosch cornering ABS.
The XDiavel S adds wild wheels, Brembo Monoblock front brake calipers, glossy paint, bright trim highlights, Bluetooth, special seat materials, and billet mirrors. On both machines, an impressive 147 ergonomic adjustments of the handlebar, seat, and footpegs can be made, helping riders tailor the bike to their personal preferences. Refreshingly, the sophisticated desmodromic valve train has relatively long 18,000-mile adjustment intervals.
Likes: Hits typical ill-handling power cruisers right between the eyes.
Dislikes: Complex, expensive, and divisively styled.
Verdict: Just possibly, the world's most exotic cruiser.
