Aprilia RX 125

Which RX 125 is on sale in 2026?

Aprilia France sells the 2025 model year RX 125, the only one listed on its website, in a single version. Unveiled at the EICMA show in Milan in November 2024, it builds on the 2021 bike with a Euro 5+ engine, completely redesigned bodywork, a shorter silencer with a matte black cover, full LED lighting and a colour digital dash. Two colours are available: Varanus Black (black and red) and Cubozoa White (white with purple graphics and red details). No 2026 version or replacement has been announced.

The RX 125 is the enduro member of Aprilia’s 125 family. Its sister, the SX 125, is a supermoto with 17-inch wheels built on the same base; the RS 125 and Tuono 125 share its displacement and power, but not its frame, which is aluminium on those bikes. According to Piaggio Group Japan, the RX 125 is built in China.

How much does it cost?

Aprilia France lists it at a recommended retail price of €4,500 including VAT, the same as in Italy and Germany. It costs slightly less than the Yamaha WR125R (€4,799); Fantic, Beta and SWM do not list prices on their websites. Until 31 October 2026, the Aprilia Days offer extends the warranty from 2 to 4 years. The RX 125 is not sold in the United States.

How good is the engine?

The 124.2 cc single (58 x 47 mm) is liquid-cooled, with double overhead camshafts, four valves, electronic fuel injection and a six-speed gearbox. Aprilia quotes 15 hp (11 kW) at 10,500 rpm and 11.4 Nm at 8,500 rpm in its technical specifications; the launch press release gives 11.5 Nm. According to Aprilia, the move to Euro 5+ cost nothing in performance. The 2021 version had received a new cylinder head, camshafts, intake and exhaust, an iridium spark plug and a Marelli MIUG4 ECU.

Aprilia publishes neither a top speed nor a fuel consumption figure for this version. In 2022, Moto125.cc recorded a true 109.1 km/h (119 km/h on the speedometer) with the Euro 5 version. The 2018 Euro 4 version was rated at 2.73 L/100 km. With only a 7-litre tank, range remains limited.

How does it ride?

The chassis is a true enduro design: steel twin-spar frame, steel swingarm, 41 mm upside-down fork with 240 mm of travel, and a progressive-linkage monoshock with preload adjustment (220 mm of travel according to the technical specifications, 210 mm according to the press release). The 21- and 18-inch spoked wheels carry 90/90-21 and 120/80-18 knobby tyres. Braking combines a 260 mm wave disc with a two-piston floating caliper and a 220 mm rear wave disc, with Bosch front-wheel ABS whose rollover-mitigation function limits rear-wheel lift. The seat stands at 905 mm and the wheelbase measures 1,425 mm.

On the 2018 version, Visordown and Bennetts BikeSocial described a light, agile and predictable bike; Moto.it praised suspension well calibrated for off-road use. The original CST tyres were judged vague on the road and insecure in the wet, and the fork a little soft (BikeSocial, Motociclismo.es). Aprilia does not specify the tyre brand fitted in 2025.

What equipment?

The equipment remains simple: no riding modes and no traction control. The new colour dash shows the gear engaged, maximum speed reached, two trip meters, average speed, trip time and instantaneous and average fuel consumption. Lighting is full LED, a skid plate protects the engine, and a USB socket, sold as an accessory, fits under the seat.

Who is it for?

Aprilia aims the RX 125 at young A1 licence riders from the age of 16; in France it can also be ridden on a car licence after the 7-hour training course. It suits riders who want a genuine lightweight off-road bike, usable in town and on trails. Its 905 mm seat does, however, call for long legs. For more road and less dirt, the Tuono 125 is the brand’s alternative.
