ApriliaRX 50

Description

The Aprilia RXV and SXV were the first bikes in the world to break the ‘single cylinder’ taboo and install a high performance twin in enduro and supermotard motorcycles. At the time it was seen as an almost impossible challenge to develop an off-road twin that would still be accessible to the riding public. But Aprilia’s R&D had the conviction, determination and experience for the job, and victories in top level competitions soon came flooding in, followed by the world supermotard championship title.

But at Aprilia, we have never been satisfied to rest on our laurels. We see racing as the most effective method of testing new ideas and solutions that we can then introduce across the range, from our flagship model to our 50 cc machines.

The new babies in the Aprilia range, the RX and the SX, are inspired by Aprilia’s world-beating off road twins. The RX 50 and SX 50 are clearly dedicated to young riders seeking the best technology around plus head-turning good looks.

The RX 50 enduro and SX 50 supermotard are high performance 50 cc machines. They are both powered by an engine of the latest generation and feature the sort of chassis that many big can only envy.

Don’t be fooled by the size of the 50 cc engine. The RX and SX are real motorcycles, and just at home on tough racing circuits as they are on the daily trip from home to school or college.

Their design speaks for itself. Their sharp, clear-cut lines derive directly from the RXV/SXV off-road style icons. Just as their bigger sisters before them, the RX and SX are on their way to create a whole new fashion in 50 cc styling.
