Hi all. I'm new to this 4-stroke game, I've been an oil burner all my life (KDX200 & 2x KX250's) but trail riding up against a squadron of 4-bangers (3xYZ450f's, a RM-Z450, and a CRF450) my KX250 is getting a displacement complex, not to mention I'm ringing it's neck. My friends and I all ride geared MX's on the trails as they are slick, quick and nimble. I've got the opportunity to throw a leg over an '04 KTM 450 EXC which would be great to get the wide ratio box and trail set up but I have never ridden one before and same goes for my mates and I don't want to hop on a trail tracktor. Could someone please shed some light on what I should expect with regard to the power curve, gear ratios, and reliability of the 450 EXC. . . . and any other little tricks I should know about it. Thanks Crew.
