aprilia SX 50



Heir to a recent prestigious off-road history, culminating in the winning of 7 world titles in Supermotard, Aprilia SX distils all the advantages of larger engines down  to 50ccs because Aprilia always uses competitions as the testing ground for new ideas and solutions to spread across the range, from the most powerful model to entry level machines.

Sophisticated chassis design

The sophisticated chassis design is a point of excellence on every Aprilia and is the result of years of experimentation when producing high-quality frames. Take a close look at the SX 50’s new perimeter frame and you’ll see all those years of experience. At 860mm high, the new tapered, compact saddle easily accommodates rider and passenger in a comfortable position, providing ample freedom of movement. The lockable fuel cap fits perfectly to the tank and significantly improves the mobility of the passenger in longitudinal movements.

A latest generation engine

The liquid-cooled single-cylinder two-stroke engine is characterised by an intake reed valve. Use of the latest technology allows this new engine to deliver exceptional performance for the category at a contained weight.
The lubrication uses a separate mixing system with a variable capacity volumetric pump. Starting is handled by the kick starter. Compliant with Euro 4 regulations, it comes with an electronically controlled carburettor and three catalysers for controlled emissions and consistently high levels of performance.

The lines are decisive and dynamic

Completely new, the lines are decisive and dynamic, expressing a contemporary style true to Aprilia's sporting DNA with streamlined fairings, enriched with racing style graphics. The headlight is integrated into the fairing and delimits the new digital instrument panel, complete, clear, modern and easily accessible thanks to the new more ordered positioning of clutch and brake cables.
