Rider Profile

Best ForThis bike suits complete beginners and learner-licence riders taking their first steps on two wheels.
PurposeIt's built as a simple, economical commuter for short urban and suburban trips rather than performance riding.
Rider FitIts low seat height and light dry weight make it very manageable for shorter or less experienced riders.
CharacterIt has an unpretentious, low-stress personality suited to easy-going, practical riding rather than thrills.
Not Ideal ForIt's not the right choice for riders wanting highway touring, spirited cornering, or genuine off-road capability.

2007 Hartford HD-125S Rider Ergonomics Assessment

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

Feet:

At 780mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2007 Hartford HD-125S, with a cramped knee angle of around 70 degrees and a forward-leaning 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.
