Rider Profile

Best ForSuits riders with at least some prior experience, particularly those comfortable with the tall seat height and single-cylinder power delivery typical of big-bore enduros.
PurposeDesigned as a versatile dual-sport machine capable of light off-road excursions, urban commuting, and occasional longer rides.
Rider FitThe 817mm seat height and tall, narrow build demand a reasonably tall rider or confidence with tiptoe stops at standstill.
CharacterA torquey, easygoing thumper that rewards relaxed, momentum-based riding over outright speed or aggressive cornering.
Not Ideal ForNot the right choice for riders chasing high-speed performance, trackday thrills, or long-distance two-up touring comfort.

2004 Aprilia Pegaso 650 I.e. Rider Ergonomics Assessment

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

Feet:

At 810mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 2004 Aprilia Pegaso 650 I.e., with a cramped knee angle of around 70 degrees and a slightly forward 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.
