2013 Aprilia SX 50

Posted on by  

With its long list of victories in various races, the Aprilia has proved us that is one of the best companies when it comes to motorcycles. Thanks to its wide experience in this segment the company gets better and better with every year that passes.

Needless to say that Aprilia puts all this experience in its new models and the so called “babies” make no exception.

Therefore, despite its compact dimensions the SX 50 is backed up by the Aprilia’s legacy so it offers top notch performances. Especially designed for young riders the new 2014 Aprilia SX 50 is powered by a 49.9 cc, liquid cooled, single cylinder two stroke engine with light alloy cylinder. The unit is fueled by a 7 liter fuel tank and sends its power to the rear wheel through a six speed transmission.

The Aptilia SX 50 is offered with a base price of $4,593.

Overview

Aprilia SX 50

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.

The new perimeter frame forms a direct connection between the steering head and the swingarm pivot, in line with the latest off-road developments. The frame is made from high strength steel to absorb all the stress that hard off-road riding can transmit. This synthesis of strength and lightness is the perfect match for the characteristics of the RX/SX 50. The suspensions are another one of the strong points of these exceptional motorcycles. At the front there is a mighty fork with 40 mm stanchions giving a wheel travel of 195 mm, more than enough to absorb even the hardest knocks. At the back, the high strength steel swingarm is damped by an advanced hydraulic monoshock giving a generous 180 mm of rear wheel travel to ensure that the RX/SX 50 can tackle even the toughest terrains.

Verdict

Aprilia SX 50

The Aprilia SX 50 looks like a mature enduro bike, but it doesn’t offer the expected performances. Try to push it a little but harder and you’ll find its limitation pretty fast. So it does exactly what it promises to, being a tamed motorcycle developed for young and beginner riders. Its price however, is a bit too much for a bike that is unlikely to be kept around more than one yer.
