A sport bike version of the 390 Duke, the KTM RC390 was presented at the 2013 EICMA motorcycle show in Italy.
Its most details had leaked a few weeks earlier.The 2014 model bike has the same 373 cc engine making a claimed
44 hp (33 kW) @ 9,500 rpm with a claimed weight without fuel of 147 kg (324 lb).
With a fuel capacity 10.0 l; 2.20 imp gal (2.64 US gal),the wet weight would be 154.2 kg (340.0 lb).
The frame of the RC is a different single piece trellis frame than the Duke,
which KTM says is stiffer than the 390 Duke.
The tires are Metzeler 110/70ZR17 front and 150/60ZR17 rear.
Where the Duke has a steering head angle of 65° (or 25° rake), the RC’s fork
has a steeper 66.5° head angle (or 23.5° rake).
The 1,340 mm (53 in) wheelbase is 27 mm (1.1 in) shorter than the Duke.
