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.
