Rider Profile

Best ForBest suited to experienced riders who are comfortable managing a long, heavy, extreme-rake custom chopper at low speeds.
PurposeBuilt as a bold, attention-grabbing custom cruiser for boulevard cruising and show-quality style rather than outright performance or practicality.
Rider FitIts low 635mm seat height is approachable, but the extreme 45-degree rake, wide rear tyre, and 320kg weight demand real strength and confidence at parking-lot speeds.
CharacterA muscular, torque-heavy V-twin with aggressive styling that delivers strong straight-line thrust and a commanding road presence.
Not Ideal ForNot for riders seeking nimble cornering, off-road capability, or a lightweight everyday commuter.

2008 American IronHorse Slammer Base Rider Ergonomics Assessment

Calculated in your browser only - your height/inseam are never sent to our servers.

Feet:

At 635mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2008 American IronHorse Slammer Base, with a cramped knee angle of around 70 degrees and an upright riding position.

Data quality: estimated (wheelbase estimated from this category's typical bike, not this model's own spec). Assumes about 30mm of suspension sag once seated (a typical street-bike rule of thumb - stiffer or softer suspension will vary). This is an approximation from category-typical geometry and generic body proportions, not a measurement of this specific bike or you - sit on it before you buy.
