About this model
About the Aprilia SX 125
The Aprilia SX 125 is a compact supermoto for A1 licence riders, built around a steel tubular frame with 17-inch wheels and a single rear shock. The 124 cc four-stroke single produces 15 hp and the bike tips the scales at just 127 kg ready to ride, making it one of the lightest and most nimble machines in its class. High-set footpegs, a flat handlebar and firmer suspension give the SX 125 a sporty, active riding stance that stands out among faired A1 rivals. The model has been continuously refined, receiving updated styling and improved electronics for 2025.
The SX 125 is designed for young urban riders who want something more dynamic than a conventional scooter. The elevated seating position gives good visibility in traffic and the supermoto suspension handles kerbs and cobblestones without complaint. Motorway use is limited by the class restrictions, but for everyday city riding it is lively and easy to park. Direct rivals include the Honda CB125R, KTM Duke 125 and Husqvarna Svartpilen 125.

Before you buy
What to check before buying
- Check the front disc and caliper for wear and leaks; aggressive city use wears pads faster than expected.
- Inspect the exhaust for cracks at the weld rings; the high-mount pipe position makes it vulnerable to knock and crash damage.
- Ask for full service history: air filter and valve clearance are commonly skipped on many examples.
- Check the chain tensioner and sprockets for wear; a correctly tensioned chain is essential for smooth drive.
- On pre-2023 examples: verify the ABS system software update has been applied.
