Encyclopedia
The Aprilia RS 125 R is a race motorcycle
manufactured by Aprilia
to race in the Grand Prix motorcycle World Championship
, built to replace the old Aprilia AF1. It was first debuted in , and it had many upgrades since. The bike won ten World Championship (one rebranded as Derbi
and one as Gilera
).
In 1991 the original tank was 12 liters, which became 13 in 1994 and 14 in 1995; the original carburator was a Dell'Orto VHSB 39, which was upgraded to a Dell'Orto VHSD 41 in 1996 and to a Dell'Orto VHSG 42 in 2006.
Since 1996 the brake specification has gone from a single front brake disc 300 mm in carbon steel to a single brake in carbon, with a diameter of 275 mm disc; in 2000 the bike returned to a double disc front braking system .
Since 2007, the bike is available in a new version, called RSA 125, for some riders. The RSA has many new details than the previous model, including improvements in the intake system and the engine. The old version, with some updates from the RSA, is still used as a customer bike and it's called the RS 125 LE.
The RSA (and the "evolution" version of the RS 125) are used not only by Aprilia, but also by Gilera
and Derbi
(rebranded as such), since all three brands belong to the Piaggio
group.
