Overall Rating 3 out of 5

Apart from the tinny two-stroke noise coming out the back of the SX125 and RX125 the new learner strokers could pass for a bigger supermoto. But get on board and you’ll find that the power and handling simply doesn’t match up to the looks.

Ride Quality & Brakes 3 out of 5

Those wide alloy bars give great steering, but even here at the top end of the 125 supermoto class the suspension doesn’t match up to the racy looks. Huge travel and soft springs mean the bike pitches back and forth and loads up in corners. Sticky tyres keeps them right side up, but you expect more from Aprilia. Good over rough surfaces though.

Engine 2 out of 5

In days gone by performance two-strokes were about hard-hitting top end power, but emissions law has put paid to that. The once class-leading Aprilia engine has had it’s goolies removed to satisfy Euro3, and the weak bottom end builds in to an unexceptional top-end. Only low-rev fuelling is better than before.

Build Quality & Reliability 3 out of 5

The build quality is superb – shiny fasteners, beautiful alloy components and tough looking plastics are up the spec of the rest of the Aprilia range. The 20 year-old engine should be reliable between piston ring changes given the necessary care – but since when do teens lavish care on a bike?

Value & Running Costs 2 out of 5

£3099 is a lot of money for a 125, especially given that the eco-changes have taken away some of the performance edge. It’s nicely built, but we’re not sure it’s worth the cash for a bike you might only keep for six months. Find an Aprilia SX125 for sale.

Insurance group: 7 of 17 – compare motorcycle insurance quotes now.

Equipment 4 out of 5

The area where the SX125 and RX125 scores over rivals is in kit – Brembo brakes, a digital dash and beautiful alloy spoked rims look lovely. But Aprilia still hasn’t equipped the motor with RS125’s electric start – so it’s left-side kickstart only. Compare and buy parts for the Aprila SX125 in the MCN Shop.

Great when it starts!

23 February 2009 by Brockfish

Bought from new. Fantastic looks / kit / handling, but very poor starting; would sometimes refuse to start. Dealer said it was 'technique' but I never had a problem with my old off-road DT250! Sold as a result. Read more
