I am just curious about he ktm 620sx. Theres alot of people complaining about the maitenence and valve adjustments and all that on the "new" four strokes. Ive never heard anybody complain about a xr 400 etc. So is the ktm more like a xr or crf engine wise?

KTM-620 is like your Honda XR 400 or 650. Older and easier to maintain.
The KTM-450RFS and 525RFS are like your CRF 450. These are racing bike and require a little more TLC.
