2018 KTM RC 390

For 2018 the KTM RC 390 offers a host of features that confirm the READY TO RACE nature of this single-cylinder supersport machine. Thanks to engineering like vertically stacked gearbox shafts, the sophisticated DOHC single of the KTM RC 390 is extremely compact and weighs in at a mere 79lbs. With its four-valve cylinder head with DLC-coated finger followers, dry-sump lubrication with crankcase evacuation, and three-way catalytic converter, it has all it needs to combine 44 hp of maximum power with impressive refinement, extreme reliability and class-leading performance. A PASC slipper clutch keeps the rear end in line while the 320 mm front brake rotor hauls the RC 390 down from speed with impressive bite and power. There is no question the RC 390 is the only choice for those looking for the most performance out of a smaller sportsport mount.
