If you want a KTM buy a KTM. If you want to step up buy a Berg :cool: There are very few after market parts for the Berg. But they come fully dressed except hand guards. Both 450's the EXC & FE's are great woods bike and full blown racers right out of the crate! Both 450's are short stroke fast revving motors. The Berg will be a left kick start, right side chain with a very good E button. The KTM is a right side kick start, left side chain and a very good E button. The KTM I feel has a more durable counter balancing system than the Berg, but it has improved to almost the same level as the KTM since KTM as took owner ship! :cool: the rear brake pedal is a little hard to use on the Berg due to the cultch being on the other side of the motor and you have to reach in a little further than on the KTM. I have two Husaberg's and really love the bikes, I would buy again. My brother and close friends all ride KTM's and I've rode most of the EXC line 200, 250, 300, 400, 450, 525. I feel there great bikes and are worth buying!
