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.
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.
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.
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.
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?
£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.

New model for 2008.
Aprilia RX125: same frame, engine, suspension and bodywork as the SX125, but the enduro-style RX version features larger wheels (21" front & 18" rear), different gearing and knobbly tyres. It's also £200 more expensive.

Looks great. sounds okay for a 125. but had all kinds of problems from not starting well to the speedo breaking

Great second hand bargain!
£1700 11kW 2009 @5800 miles. Bought it with nothing done to it... Only things i've had to do is rebuild it, de restrict it and changing the brake pads this week. Tyres have done 7600 miles and don't need changing.. Great buy

Great when it starts!
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.
