I'm in the market for a new 4-stroke, and am mostly considering either a YZ or WR 450...but have lately been looking at KTM's too. I have searched and read all previous posts about all three bikes. That said, does anyone have any PERSONAL experience with the '05 bikes? I do both desert and tight woods riding, with little or no MX. I'm about 6' tall, 160 lbs, and a novice rider. The things that concern me about the WR are that Yamaha totally screwed up everything to make it green sticker compatable. Why can't they just make a YZ with WR components? From what I've read, the WR is VERY hard to re-jet, not to mention all the other "free" mods that you have to do to it, just to get it to run. I really want electric start and lighting, but from what I've read, I'd rather go with a YZ and a auto-clutch than buy an '05 WR, just because of all the crap that you have to do to the WR to make it run. What concerns me on the KTM is reliability, support, ease of maintenence, cost, and cost of parts. From looking at the pictures, I can't see where the oil filter is...I've read that it's just a screen that you get to on the bottom of the engine, and it has a history of stripping out. What about valve adjustments? Do you have to do them more often than the Yammi? What about replacement parts? Are they as readily available, and do they cost more? Also, how is KTM at customer service? Are they willing to pony-up and fix stuff that is a manufacturing defect, even out of warantee? Lastly, what do they cost? The KTM website doesn't list prices. From what I've read on this forum, the KTM costs at least $1000 more than yammi.
