Engine Displacement to Weight (cc) 2 Exterior. Construction. Standard 2010 KTM Duke 690 R. $10,998 MSRP. 2010 KTM Super Duke 990 R. $14,398 MSRP. Powered by a 373cc liquid cooled, 4 stroke, 4 valve single, the little bike punches hard with 44 HP and 27.5 lb-ft of torque. Coupled to a bike that weighs just a hair under 390 lbs wet, almost supermoto levels of power-to-weight are achieved. This means the 390 Duke is extremely flickable, and will happily carve any corner you stick its nose into. instead of pondering about the weight, go test ride one and remember that changing the exhaust and filters + the Akra map make it a lot better than stock.
