URCRAZY; never seen a KTM atv. Do you know what type of frame that's being used? If the new 650 honda performs like a 650 then I would have to get that monster. I had a chance to ride with a friend of mine that has the 450r with pipe/jet kit & his jaw, just dropped after witnessing the acceleration of my KTM 525sx. The 450r is sweet, no doubt but since I already have a 01 Raptor with pipe/jet kit, cam, piston, etc. it holds it on pretty well and I would be starting from scratch. Hopefully the new 650 can make me out to be a believer.
