New rims have helped shave an impressive 3.4 kg unsprung weight off the RC390 and the upgraded ByBre braking system shave another kg  while the frame is now 1.5 kg lighter also.

EURO5 updates on the liquid-cooled, single-cylinder four-stroke engine with twin overhead camshafts, four valves, and electronic fuel injection have helped boost torque with the aid of a new air-box design.

From an electronic standpoint, the new generation KTM RC 390 sets the benchmark for the small displacement Supersport segment, boasting a selection of rider aids usually only available on bigger motorcycles, namely Supermoto ABS, Lean angle sensitive Cornering ABS and Cornering MTC, along with the optional Quickshifter+.
