Rider Profile

Best ForThis lightweight, low-powered supermotard is best suited to beginner and novice riders building confidence, or licensed learners looking for a nimble first bike.
PurposeIt's designed for playful, flickable fun on tight urban streets and twisty backroads rather than outright speed or distance riding.
Rider FitThe tall 905mm seat height and slim, minimal 101kg dry weight suit riders comfortable balancing a tall stance, though shorter riders may need to tip-toe at stops.
CharacterIt has the character of a scrappy, agile mini-motard that rewards aggressive body language and quick direction changes over raw acceleration.
Not Ideal ForThis is not the right bike for highway touring, carrying a passenger, or riders who prioritize outright power and long-distance comfort.

2005 AJP PR4 125 Supermotard Rider Ergonomics Assessment

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

Feet:

At 850mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with tip-toe one foot on the 2005 AJP PR4 125 Supermotard, with a relaxed knee angle of around 130 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.
