Aprilia Rs 125 Extrema 93

Overview[edit]

Presented in the Spring of '92 and sold from June, the RS 125 Extrema replaces the previous series AF1 reaches its peak with the Futura Pro Sports, presented just before the Extreme.

As we saw in the 90s with AF1 AF1 Futura Summary Sport and '90, '92 sees the coexistence of two different models in two series: first the Futura AF1 Sport Pro and other new series RS Extrema Autumn '92 also available in new color replica Reggiani. However, unlike the '90s when both the Sports Summary and future are presented in time to take part in the Sport Production championship, for the '92 season, only the Futura Pro Sports is submitted in time to be entered in the league. So while the future Pro Sport is marketed primarily to be sold to those who run sports league in production, the RS Extrema lives its first year of life only as a street bike.

The Extreme is essentially a new bike to the future and an exciting new addition to "dress" features a new fairing and a beautiful, flowing tail, the most important changes are a brand new chassis - in aluminum - designed from scratch and to mark the sign of discontinuity with the AF1 series, a new aluminum swingarm with two arms instead of the single-arm steel previously used. Unfortunately, the quality of the Extrema is lower than the previous Futura in some detail how the rider and passenger footrests, but the quality of assembly and painting is still better.

The Extrema remains in production until the end of '94 and is flanked by two versions produced in Sport Production in '93 and coloration Reggiani Replica Replica Chesterfield in '94.
