Rider Profile

Best For	Well suited to beginner and learner riders thanks to its light weight, low power, and manageable seat height.
Purpose	Designed primarily for light trail riding, green-laning, and off-road learning rather than speed or distance.
Rider Fit	Its low dry weight and tall but slim enduro seat make it easy to manage for smaller or less experienced riders once moving, though the seat height can challenge shorter riders at a stop.
Character	A nimble, playful small-capacity enduro that rewards momentum and finesse over outright power.
Not Ideal For	Not suited for riders wanting high-speed touring, motorway cruising, or carrying a passenger in comfort.

Units

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

Feet:

At 830mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with balls of both feet on the 2015 Aprilia RX 125, 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.
