Rider Profile

Best ForBest suited to riders who already have some experience with heavy, torque-driven cruisers, since the low-slung chassis and minimal suspension travel demand a deliberate riding style.
PurposeBuilt for stripped-down, stylish urban cruising and short blasts rather than outright speed or distance.
Rider FitThe very low 660 mm seat height makes it accessible for shorter riders, though the forward-set controls and limited ground clearance suit a relaxed, feet-forward posture rather than an athletic riding position.
CharacterA bold, blacked-out custom cruiser that trades comfort and range for attitude, torque, and classic Harley presence.
Not Ideal ForNot a good fit for riders wanting long-distance touring comfort, aggressive cornering ability, or any off-road capability.

2011 Harley-Davidson XL 1200X Forty-Eight Rider Ergonomics Assessment

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

Feet:

At 660mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2011 Harley-Davidson XL 1200X Forty-Eight, with a cramped knee angle of around 70 degrees and an upright riding position.

Data quality: measured. 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.
