The RC 125 is KTM's small-capacity supersport-styled machine, built around a 125 cc single that shares its engine design with the Duke 125. Its bodywork borrows the look of the larger RC 390 and it is positioned for markets with tiered licensing, where its power sits at the entry-level licence limit. The chassis is a steel trellis-style frame with WP suspension and Brembo-developed brakes, with ABS fitted as standard (it can be switched off).
