At work here is again a compact, single cylinder lightweight engine. The 373.2 cc mill weighs just 36 kilograms. Double overhead camshafts, four valves, a forged piston and a Nikasil-coated cylinder work to deliver 44 hp/32kW. Force feed lubrication with crank case evacuation lowers the crank drive’s rolling resistance, contributing to the powerful torque says KTM. The KTM 390 Duke retains the ultra-light trellis frame and cast aluminium swingarm shared with the Duke 200. The trellis frame of course had to enhanced to handle the increased power from the 390’s engine. As with all other katooms, suspension components by WP Suspension are top notch. Disc brakes have been developed by Brembo and the disengageable 9MB ABS by Bosch are standard.
The new 390 Duke weighs in at less than 150 kilograms fully fuelled, leaving you straddling a very competent handling package which we estimate might be priced at around 2 Lakhs. As we’ve seen before expect the engine bottom to be shared with a new Pulsar, expected to be launched in both naked and fully faired versions.
Details are limited now, do check back when we have more information. Meanwhile, feast on these images!
