KTM Supersport RC 390 2023 A high-performance Supersports vehicle with its origins firmly established in the racetrack, the KTM RC 390 was introduced in 2023. 

The 373 cc liquid-cooled, single-cylinder, four-stroke engine found in the KTM RC 390 is used to its full potential. With updated engine mapping, increased torque, and a smoother, more direct power delivery, this cutting-edge powertrain produces performance that is unrivalled.

The KTM RC 390 accelerates off the line and grabs the lead thanks to a bigger airbox, more torque, and an incredibly smooth throttle response. With a new Ride-by-Wire system, it also has the advantages of optional Quickshifter+, more accurate engine mapping, and traction control.

The KTM RC 390's cylinder head has four valves, double-overhead cams, and ultra-hard carbon-coated cam levers, resulting in more power while maintaining. The KTM RC 390's exhaust features stainless steel headers and an aluminium muffler, taking design inspirations from the MotoGPTM RC16. These components not only look the part, but also give the KTM RC 390 a distinctive, throaty rumble as it surges through the gears and into the redline.

The slipper clutch opens when the engine back-torque is too high and prevents the rear wheel from locking up during harsh braking. It also shuts with the force of the clutch springs when you apply the throttle. This ensures optimal control, prevents unnecessary rear wheel noise, and allows the clutch lever to be depressed with almost no pressure.
