What category is the 2016 Aprilia RS 125?

Slightly confusingly the 2017 RS125 replaces the 2011-2016 RS4 125, which itself replaced the 2006-2012 two stroke RS125 In the majority of countries, however still continues to carry the RS4 moniker in some!

compared to the previous version it is Euro 4 compliant and now comes with ABS.

Optional Extras include a quickshifter, USB port and smartphone connectivity.

There is a MotoGP Replica edition which includes the quickshifter.

Rider Profile

Best For	Ideal for beginners and A1 licence holders; a forgiving, learner-friendly sportbike that also rewards experienced riders honing technique.
Purpose	A pint-sized track-styled sportbike built for spirited backroad riding, carving corners, commuting, and learning proper sport riding skills.
Rider Fit	Light 144kg with a committed sport riding position: clip-on bars, 820mm seat and rear-set pegs. Compact and manageable but leaning-forward and firm.
Character	A miniature superbike with real GP-inspired attitude — eager, revvy single that must be worked hard, delivering big-bike thrills at modest speeds.
Not Ideal For	Not for those wanting outright speed, relaxed touring comfort, two-up practicality, off-road use, or a laid-back upright commuter.
