I have had KTMs... 450 MXC , 525 EXC , 250XCF , 250 XCF W ( 280 kit) all dual sport bikes . ALL had EE soft seats ( my Berg has a EE soft tall ) . I wanted a 390 , but could not pay asking price ! so I found a smoking deal on a FE 450 loaded with goodies . I am running the mapping on begginner and have a G2 throttle cam ( 400 CAM ) , with butt plug in rear ( muffler ) . My friends say my bike is smooth and about the same as a KTM 400 . I think my 450 has LOTS of power , and if I want the massive power of the 450 again , I just tune it back up . ( stock throttle cam , mapping on race , and remove butt plug ) The 390 is always going to be a 390 . I say buy a left over 2009 FE 450 for a good deal , and detune it ( like I did ) and ride it with cash left over !! My local dealer has a 2009 FE 450 with free headlight /tailight kit on it ! I do love the 390 , but I went where the DEAL was . I think my FE450 rides like a 390 , its very nimble , all 3 Bergs ( 390,450, 570 ) all weigh the same . I think the Bergs all out handle ANY Ktm or DRZ . Its heavy picking it up , but riding it , WOW deels like I am on my 250s again with a MASSIVE motor ! I am very happy with my detuned 450 . Mine is MS street legal , so headlight/tailight/brakelight and 1 fold up mirrior .
All my KTMs did great on street and trail , its a dirtbike , so just remember that as you ride it on the street . But the Berg is CRAZY fast , I run 13/50 gearing to smooth out the power . The stock 13/52 felt " jerky " , snappy , and 1st gear was short . with 13/50 bike is easy to ride now . GOOD LUCK !! I think the Berg ( any Berg ) is the only way to go !!
