Some of the intricacies of the Lego Creator Expert Harley-Davidson Fat Boy include solid-disc Lakester wheels, teardrop fuel tank with printed Harley-Davidson logos, and a Milwaukee-Eight engine. The really cool part is the Milwaukee-Eight V-twin which sports moving pistons that engage when you spin the rear wheel. The handlebar turns the front wheel, you can move the gearshift and the kickstand also deploys. You even get dual exhausts and levers for the transmission and brakes, all capped off by the same Wicked Red color scheme as the actual bike too. The bricked-up bike model measures more than 7 inches high, 7 inches wide, and 12 inches long, and, with 1,023 pieces in the box, it'll probably make for a nice long afternoon of assembly.
