Rider Profile

Best ForThis bike suits an experienced rider comfortable with a long, heavy, raked-out custom cruiser that demands deliberate, low-speed handling skill.
PurposeIt's built as a show-quality boulevard cruiser and style statement rather than a performance, touring, or off-road machine.
Rider FitThe extremely low 660 mm seat height and stretched, laid-back riding position favor shorter riders and relaxed cruising rather than aggressive body positioning.
CharacterA big-inch, chrome-and-billet custom with a springer-style front end, fat rear tyre, and V-twin rumble that rewards riders who value presence and style over agility or speed.
Not Ideal ForThis is not the bike for riders seeking cornering agility, off-road capability, or serious long-distance touring comfort.

2011 Ultra Lowdown Drop Seat 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 Ultra Lowdown Drop Seat, 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.
