The Aprilia SX 50 is just as fun as its sportier sibling, the RS50, but is easier to use and much more comfortable - especially for taller riders.

The SX 50 is an ideal first partner if you want to pass your full UK motorbike test and like riding off the beaten track You can ride it on a provisional driving licence, providing you've done a CBT, meaning it's among the cheapest ways into two-wheeled fun.

This version of the Aprilia SX 50 went off sale in 2018 and was replaced by a new Euro4-compliant version. It remained a two-stroke, however. 

There is a thriving online community for Aprilia owners at the Aprilia Forum.

The chassis can handle way more than the 50cc lump will ever be able to throw at it, and as such it's great fun keeping the momentum up in corners. The suspension may be non-adjustable but it copes fine with hard cornering and braking.

No amount of throttle or clutch slip will ever get the Aprilia off the line quickly, from then on up, however, it's a gas. Gather a bit of momentum and things get much better. Despite the single figure power output, the light, well-spaced gearbox helps keep the tacho needle firmly in the top half of the rev counter. Expect to see 60mph in top gear with the right conditions.

If you buy a second-hand SX 50 then chances are it's spent most of its life being ridden hard by a 16-year-old who only put cheap oil in it. Check for signs it's not been looked after.

We've got just one Aprilia SX 50 owners' review on the site, with an overall score of 5 stars out of 5. The owner loves their two-stroke off-roader, although they do report some problems with the bike's top end.

At £2399 the SX was cheaper than the RS 50 but offers the same performance. If you really want to look after it you'll have to use top quality two-stroke oil, which isn't cheap.

In 2019 you could still buy the Euro4 SX 50, priced at £3499. It was available in red and green colour schemes. We've yet to review this model. 

Equipment

3 out of 5 (3/5)

As you'd expect on a supermoto, equipment is basic, with only the bare essential clock functions and non-adjustable suspension. But you don't really need anything else.
