Arizona’s DP Customs has unveiled its latest project, The Mack, based on a 2000-model Harley-Davidson XL1200. According to Jarrod and Justin Del Prado — the brothers who make up DP Customs — the machine was “built to perform with no expense spared.” A new 1250cc motor is decked out with performance cylinders, pistons, ported heads, big valves and Screamin’ Eagle cams, all coated with an ultra-thin bright aluminum coating. Additional performance upgrades include forks and shocks from Ohlins, brakes from Brembo and carbon fiber wheels from BST. A diamond-stitched seat draped in Alcantara completes the look. As for whether The Mack belongs on the race track or the street, the guys at DP Customs put it succinctly: the answer is both.
