Aprilia RS125


  • Cool exhaust, big bike size
  • Looks good and goes well


  • No fuel level indicator, tyres
  • On the pricey side


It's powered by a Euro 4 compliant liquid cooled 124.2cc single cylinder four stroke engine, producing 14.8bhp at 10,750rpm and maximum torque at 8,000rpm. RRP is £4,700 or £4,800 for the MotoGP Replica which includes the quickshifter.

Features include:

  • Aluminium frame
  • 300mm disc up front with J.Juan radial 2 piston caliper
  • 218mm at the rear with J.Juan single piston caliper
  • Bosch single channel ABS system
  • 41mm upside down fork with 110mm travel
  • Rear shock with 120mm travel
  • LED tail light
  • 6 speed gearbox and fuel injection

Rather confusingly the 2017 RS125 replaces the 2011-2016 RS4 125, which itself replaced the 2006-2012 two stroke RS125. Compared to the old version it's Euro 4 compliant and now has ABS.

The Tuono 125 is basically the same bike without a fairing, a mini fly screen, black swingarm, more pillion friendly one piece seat, 10mm lower seat height and a more relaxed riding position.

There's space for an iPad mini under the seat and a USB port can be added for recharging. Uniquely the exhaust is completely hidden in the bottom of the fairing so it looks great from both sides and the 6 split-spoke cast Aluminium 17" wheels take a 100/80 tyre at the front and 130/70 at the rear.

Accessories include a quickshifter, USB port and smartphone connectivity.

Colours: Black, silver, red/green/white (MotoGP)

Model History

Aprilia launched the RS125R Extrema in 1992 with a 125cc single cylinder 34bhp engine, restricted to 15bhp to comply with UK law. There are some unrestricted examples knocking around but make sure that they can be ridden legally.

In 1996 the dropped the R and Extrema from the name and started calling it just the RS125. It gained an new Rotax 122 engine and new fairing but the weight remained at 142kg wet.

In 1999 there was another fairing and air duct change while the wheels moved from 3 spoke to 5 spoke.

2006 introduced a modern fairing styled on the RSV1000R, Y-spoke wheels, halogen lights and digital dashboard.
