About the Aprilia SX 50
Powered by a Euro 2 compliant liquid cooled 49.9cc single cylinder two stroke engine, producing around 6 bhp.
The engine itself only weighs 15kg and by only including a kick starter Aprilia shaved even more off.
The Aprilia RX50 is essentially the same bike but with larger spoked wheels, off-road tyres, a smaller front disc and a 50mm higher seat. Both bikes can be limited for 16 year olds or derestricted to unlock the 50mph top speed.
The wire-spoked 17" wheel takes a 110/80 tyre at the front and 130/70 at the rear.

| Best For | Best suited to young or novice riders, often pre-licence teens, learning throttle control and bike handling in a low-stakes environment. |
| Purpose | Built as a lightweight supermoto-styled 50cc machine for playful street riding, learner training, and short sporty jaunts rather than serious performance. |
| Rider Fit | Its featherweight 99 kg build and low-effort controls make it extremely easy to handle and flick around for smaller or lighter riders. |
| Character | A cheeky, nimble little supermoto that encourages flickable, energetic riding despite its modest two-stroke power output. |
| Not Ideal For | Not suitable for taller or heavier adults, highway commuting, or anyone wanting real straight-line speed or long-distance comfort. |
