Much like the Hellfury, the Diabolus is best described as an aggressively designed custom chopper sporting modern, unconventional design cues, similar in design to the real-life West Coast Choppers El Diablo. In comparison to the Hellfury, the bike is identifiable by its thinner frame, different exhaust pipes, exhaust note, and an added buddy bar above the rear fender. The bike is available with any one of two gas tank design and any one of two exhaust pipe deigns.
The unfinished GTA IV version of the bike differs slightly from the final TLAD design, featuring a more compact and less radically designed gas tank that features the Diabolus name, and lacking any rear license plate.
The Diabolus in The Lost and Damned is a gang vehicle ridden by members of The Lost Brotherhood.
The Diabolus' performance is fairly poor, as the bike has only average acceleration and a top speed of around 120 kph/74 mph. The bike suffers from poor steering that constantly results in understeers and wide turning radius's if cornering in full throttle. In other respects, the bike's grip and brakes are average.
Although the bike is durable in firefights, its long length, as are many long choppers in the game, makes it impractical for agile chases, and is normally incapable of performing wheelies or stoppies.
The Diabolus is featured extensively in The Lost and Damned's storyline as the bike of choice for several prominent Lost members, including Jason Michaels, Brian Jeremy, Terry Thorpe and Clay Simons, and feature unique color scheme:
While these bikes features colors that are consistent throughout their appearances in The Lost and Damned, their gas tank and exhaust pipe designs may change in each appearance.
