"From the painted then brushed aluminium swing arm, the gloss black paint of the engine, the aluminium detailing on the motor, the way Ducati put the water pump inside the V-twin to give it a cleaner look, and those wheels all gloss black and aluminium. For me it’s the wheels on the S that make it. On the cheaper £15,795 XDiavel it’s pretty much the same spec mechanically but there’s matt paint on the tank and engine, a painted swing arm, less bling wheels and the same 50mm Marzocchi fully-adjustable forks but no Diamond Like Coating as on the S. It also replaces the S version’s top-line Brembo M50 brake calipers for slightly lower-spec, but still good, M4 32 front calipers. Both get full LED lighting front and rear but the S gets a Daytime Driving light to give it that distinctive look so you instantly know it’s an X-Diavel S."
