1991–2007: RSV and RSW

From 1991 to 2007 the bike was used in two different configurations: first the original RSV 250, then the RSW 250, a new version of the RSV used by factory teams and riders. Another version named RSW 250 LE was raced by semi-works teams while privateer riders usually raced the RSV 250 kit ''production racer''. Initially the front braking system was available either with 273mm carbon discs or in 300mm carbon steel, then from 1994 onwards the only version used was the double carbon disc, either with 255mm or 273mm length. The rear braking system was one-disc carbon steel, initially at 184mm, then from 1996 at 190mm.

2007–2009: RSA

In 2007 the bike was made available in a new version, amended to RSA 250, characterized by many different details from previously, including a revised intake system and the new disposition of the gear unit and of thermal groups. The measurements of the frame changed to use a longer swingarm, and obtain benefits both in acceleration and traction. Another change involved use of three accelerometers to get more data for the management of the power of motion in situations of low adhesion in order to speed up the development of Aprilia RSV 4 which entered the Superbike World Championship in 2009. The new engine was more powerful with a wider operational period, between 6,000 rpm to 13,500 rpm for maximum power. The RSA (and the "evolution" version of the RSW) were used not only by Aprilia, but also by
