I have 2 fx 650's 2 fx 600's . a fc 500. all with big valve heads cams ,trick cranks the usual stuff. etc. a couple wr450's for the kids. a few other junk bikes like the klx 300, and xr650 L. for my wife.
This 06 ktm with a 570 kit and cam will out run all the big bergs and it has a smoother motor. the 8/06 cam is like magic. it is used in the ktm 560. I am having one ground for a 650 berg to see if it works the same as it did on the ktoom. I left ktm for the bergs, I just might be back.
Lets ride.
