Heloo,
The KTM Duke 390 is for only racing maniacks.
The Design- its really agressive looking, similler to that of 200 in size and shape. Visible differences are orange alloya, a powder coated trellis frame and new graphics, a larger fuel tank and wider handlebars
The Engine and Performance- Its my favorite engine. 373.2cc s ingle cylinder, liquid cooled, massive 43bhp @9500rpm and 35Nm of torque.which gives a great p/w ratio 296bhp per tonne. So because this kind of engine it accelrate 0-100 in just 5.6sec, and thats all racers gone love it. concedering the power the bike handles really well, you can take cornars confidiently. I really dont want to write about the performance because if you really want to know, you should ride it by yourself.
Your really a racing enthuziast the just go for it.
