My son is moving up from a klx110 to a 65. I have almost made my mind up on buying a ktm65 reason why not the kx or rm is that I like the suspension a lot better and the hydro clutch. So here is questions I'm ask if you guys can help me out on please, we are looking at a really clean ktm65 2008 with out the power valve. The 2009 released the power valve motors, should we really be looking for a 2009 or newer for the power valve ..? We plan on doing a lot of trail riding and twice month track riding maybe more not sure as of now And last ?is I here people saying the ktm cost more to take care of but when I compare parts ktm vs kx the parts are like $10-$20 more for ktm.. If maintenance the bike regularly there should not be a problem right ..? But my big ? Is power valve and are we really going to notice on track compared to power valve bikes ?
