This is the RS 125 model variant of the Aprilia range, available to buy at On Yer Bike.
Sharp, sporty and ready for the open road, this brand new Cyanide Yellow learner-legal sports bike arrives with 2 keys and rider aids that build confidence from the very first ride. If you want race-inspired looks without stepping up to a big, intimidating machine, this is where the story starts.
This 2026 Aprilia RS 125 is powered by a 124cc single-cylinder, liquid-cooled four-stroke engine producing 15 hp, which is the maximum allowed for the class. It is eager and revvy, and the compact chassis feels light and agile, so it is just as happy threading through town traffic as it is carving along a twisty B-road. The riding position is tucked and sporty, yet it remains manageable for newer riders. ABS keeps braking stable and predictable in poor conditions, while Traction Control adds extra reassurance on slippery surfaces. It is perfectly suited to holders of an A1 motorcycle licence, making it an ideal learner-legal sports bike, a stylish commuter and a great first step into the world of full-size supersport machinery.
The bike is supplied by On Yer Bike, an official Aprilia dealer near Aylesbury, UK.
