Engine
Boasting the latest generation of KTM's LC4c engine, the KTM 125 SMC R features a compact, 124 cc single-cylinder powerplant, churning out impressive power and effortless acceleration. This makes it ideal for charging through motorway traffic, or playing around in the parking lots.

THE BACKBONE
Frame
The new design features a 2-piece construction composed of an all-new steel trellis main frame with a pressure die-cast aluminum subframe. Not only designed for overall looks, the primary objective of the frame design is to enhance vehicle dynamics by augmenting torsional rigidity, improved agility, and enhanced feedback from the chassis.
