The Aprilia RS125 is a GP derived replica sport production motorcycle. It is powered by a single cylinder 2-stroke, Nikasil coated aluminium cylinder block, liquid cooled 124.8cc Rotax engine.

Aprilia has had many Grand Prix victories in the 125cc and 250cc 2-stroke classes. With years of racing experience, Aprilia has released a new version of the RS125 with new looks, performance & styling.

Key features of the new Aprilia RS125 are: New frame technologies that promise superb agility and are much lighter than previous model. Combined with new frame structure and material the frame is a re-creation of the one used on the Aprilia GP125 racing bike. New racing wheels with Y-spoke configuration make the rim lightweight while retaining high strength. They are made from a die cast moulding process which reduces unsprung weight and guarantees rigidity under racing conditions.

The Aprilia RS125 is noted by many people as its engine is prone to breaking up easily in high revving situations. This means the engine needs to be rebuilt several times.
