About the Aprilia RX 50

Powered by a Euro 2 compliant liquid cooled 49.9cc single cylinder two stroke engine, producing about 6 bhp. RRP the RX50 was introduced in 2006.

The engine itself weighs just 15kg and by just including a kick start Aprilia shaved even more off.

The Aprilia SX50 is essentially the same bike but with 17" wheels, road going tyres, a larger 300mm front disc and a 50mm lower seat. Both bikes can be limited for 16 year olds or derestricted to unlock the 50mph top speed.

The wire-spoked 21" front wheel takes a 90/90 tyre and the rear 18" a 110/80.

Rider Profile

Best For	This is a learner-legal 50cc machine best suited to new or younger riders taking their first steps on two wheels.
Purpose	It's designed as a supermoto-styled commuter and playbike for short urban and suburban trips rather than serious performance riding.
Rider Fit	Its low 132 kg weight and 860 mm seat height make it easy to handle and confidence-inspiring for smaller or less experienced riders.
Character	Nimble, light, and eager-revving, it rewards flicking through traffic and tight corners rather than outright straight-line speed.
Not Ideal For	It's not the right choice for highway touring, carrying a passenger comfortably, or riders wanting real power on tap.

Feet:

At 830mm, a rider of 68.9" with a 31" (estimated) inseam will reach the ground with balls of both feet on the 2011 Aprilia RX 50, with a cramped knee angle of around 70 degrees and an upright 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.
