Rider Profile

Best ForBest suited to riders who already have experience with heavy, long, low-slung cruisers and understand how a springer front end changes low-speed handling.
PurposeBuilt for laid-back boulevard cruising and show-stopping style rather than outright speed or distance-eating touring.
Rider FitThe low 640mm seat height helps shorter riders reach the ground, but the substantial dry weight and long wheelbase demand solid upper body strength for slow-speed maneuvers and parking.
CharacterA classic American cruiser statement piece with a nostalgic springer front suspension, wide rear tire, and deep V-twin rumble that prioritizes attitude and presence over performance.
Not Ideal ForNot for riders seeking sharp cornering ability, off-road capability, or a nimble machine for tight city traffic and quick direction changes.

2004 Harley-Davidson FXSTSI Springer Softail Rider Ergonomics Assessment

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

Feet:

At 640mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2004 Harley-Davidson FXSTSI Springer Softail, 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.

Risk: THESE SITUATIONS COULD CAUSE SERIOUS PERSONAL INJURY OR CREATE A FIRE HAZARD FOR PERSONS OR PROPERTY ON OR NEAR THE MOTORCYCLE.

Remedy: DEALERS WILL TEST EACH CANISTER FOR BLOCKAGE, THEN REPLACE AS NECESSARY. THE RECALL BEGAN NOVEMBER 4, 2004. OWNERS SHOULD CONTACT HARLEY-DAVIDSON AT 1-414-343-4056.
