Rider Profile

Best ForThis is an ideal bike for new or learner riders, including those on a restricted license, thanks to its light weight and modest power output.
PurposeBuilt as a sporty, race-replica styled machine for learning proper sportbike ergonomics and cornering technique at accessible speeds.
Rider FitIts low 120 kg weight and compact dimensions make it very manageable for smaller or less experienced riders, though the sporty seat height and committed riding position suit shorter to average-height riders best.
CharacterA nimble, high-revving little sportbike that rewards momentum-carrying, corner-focused riding rather than straight-line speed.
Not Ideal ForThis is not the right bike for experienced riders seeking real power, highway touring comfort, or two-up long-distance travel.

2016 Aprilia RS4 125 Rider Ergonomics Assessment

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

Feet:

At 820mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 2016 Aprilia RS4 125, 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.
