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.
