Like a few other custom bike builders, American IronHorse had a short, but sweet, run. Its start-up in 1995 brought a well thought-out, perfectly constructed gaggle of choppers to the custom business. All the tin and leather were designed and fabricated in-house. The powder-coated frames were specially designed by Daytec for the American IronHorse line-up. The engines were modified the factory, and the transmissions were made by Baker. The custom bikes were all hand-built in a state-of-the-art, 224,000 square foot factory in Fort Worth, Texas. Sadly, building one of the best custom choppers out there didn't pay off in the long run, and it became one of those businesses that got hit hard by the turn of the economy. By spring of 2008, production ceased and its assets were sold at auction.
The IronHorse line-up starts with the basic S&S 111 ci engine, but since so many were produced the 117 ci or 124 ci engines are also likely options. Keep in mind, the more horsepower, the less S&S warrantied them. The Slammer pro-street has the 111 ci. All of the AIH engines come chromed or polished and feature diamond-cut, powder-coated barrels to match the paint. They're paired with a Baker six-speed transmission, and it’s an impressive ride.
The Slammer pro-street sports an A-frame softail-style swing-arm, combined with a pair of Progressive manually adjustable shock absorbers, and it provides a much gentler ride than appearances would indicate. As with all the AIH bikes, the front suspension is telescoping front forks and are raked at 42 degrees (38° frame plus 4° raked triple trees) add to the frame the patented Super Stretch, five gallon tank, and you've got ride that will go places. Rear suspension is a twin-sided swing arm with Progressive shocks, sitting atop a huge 10.5-inch wheel with an equally fat Metzeler 280/35V R18 tire. Instrumentation is simple but efficient, with a speedometer, odometer, trip meter, tachometer, hi/low beam, turn signals, and Neutral-light all housed together and easy to read, with the exception of the digital information center, which can be tough to decipher in the sun.
With 4.8 inches of ground clearance and weighing in at 610 pounds dry, the 100 inch long bike is just a little bit shorter than several AIH models, making its turning radius slightly easier. The solo leather seat puts the driver at 26.3 inches off the ground and the forward controls combined with the rake is more comfortable than expected for a variety of riders' sizes. Strangely, the shorter statured riders seem to like the seat and fit, better than the taller riders. The extra fat rear tire makes this pro-street a thing of beauty, but don't plan of enjoying the twists with it.
