A livery edition of the RS 125 finished in the #31 colours of Tetsuya Harada, the Japanese rider who won the 1993 250cc world title and a string of 250 GPs for Aprilia before leading its 500cc effort in 1999. Mechanically it is the regular RS 125 two-stroke with the race-derived aluminium frame; what sets it apart is the paint scheme honouring the factory rider.
