American IronHorse, a Texas-based motorcycle production company founded in 1995, underwent a complete reorganization in 2007. In the process, its line of motorcycles was significantly trimmed down to just five models for 2008. The Slammer, its top-of-the-line cruiser, was one of the few to make the cut—and it was only in production for one more year before the company folded.
The standard engine was an S & S 1820cc air-cooled V-twin, but buyers could opt for an S & S 117 or 125 engine. In 2007 the Slammer got a new fuel-injection system, which was continued in 2008. The 1820cc offers 110 bph and 115 ft/lbs. of torque; the other engine options offer more, of course. The engine works with a six-speed chain-driven transmission mounted on the right side; final drive is belt-driven. American IronHorse reworked its clutch in 2006, so shifting in the 2008 models is smooth. Stopping power for the 742-pound machine comes from double disc six-piston calipers in front and single disc four-piston calipers in back.
The 2008 Slammer features Venomous dual tanks that run along either side of the backbone. A four-inch top tube stretch and an extreme 45-degree rake contribute to the long 85-inch wheelbase—and to the lean, elegant lines of the bike. The leather seat is set at a low 25 inches just in front of the rear wheel. The Progressive air-ride suspension lets the rider adjust the cruiser’s distance from the road, but the result can be a pretty rough ride. A brawny telescopic fork provides front suspension; rear suspension is twin-sided swing arm and an adjustable spring pre-load shock, with adjustable rebound damping.
American IronHorse offered 18 different base paint options, ranging from Atomic Green to Race Reddi red, and an array of graphics designs, so each buyer could customize the look of his or her bike. Since the custom paint package came with the chromed engine, rims, fork, pipes, and belt guard, the Slammer could come with plenty of bling.
