The RS4 125 is renamed the RS 125 for 2017, to celebrate 25 years of the RS model.

The new RS 125 version is available in two liveries: Silver Speed and Black Speed. Probably the biggest difference with this revamped family involves the powerplant. While the previous generation ran with a two-stroke engine, its successor packs in a cleaner, liquid-cooled, four-stroke thumper. The one-lung mill is slightly oversquare with a 58 mm bore and 47 mm stroke for a total displacement of 124.2 cc and a relatively warm 12.5-to-1 compression ratio.
