Rider Profile

Best ForSuits riders who have moved past a beginner bike and want a light, single-cylinder machine that rewards confident throttle and brake control.
PurposeBest suited to everyday urban riding, twisty backroads, and occasional light green-laning rather than outright speed or long-distance touring.
Rider FitThe 780mm seat height and slim, lightweight chassis make it accessible to riders of average or shorter stature, with easy low-speed manageability.
CharacterA torquey, easy-to-read single-cylinder supermotard that feels nimble, playful, and forgiving in mixed urban and rural riding conditions.
Not Ideal ForNot the right choice for riders chasing high top speed, long motorway touring comfort, or serious two-up passenger accommodation.

1998 Aprilia Pegaso 650 Rider Ergonomics Assessment

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

Feet:

At 870mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with tip-toe one foot on the 1998 Aprilia Pegaso 650, with a cramped knee angle of around 75 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.
