Two years ago, I sold my fully setup and california plated 05 wr450 for a KTM 450. I did that for two reasons. 1) the ergos on the KTM are fantastic, they really are; and 2) the wr450 is really very heavy. I also wanted to try out the orange bikes. Well, that was two years ago. Today, I am riding an 06 ktm300, mainly because that's all I could afford after dumping $10K into that KTM (multiple rebuilds with only 80 hrs) trying to keep it running. It was VERY frustrating to say the least. I had heard about problems with that particular KTM, but in my arrogance, I assumed that I would be the exception... I wasn't. I ended up cutting my losses and parting it out and buying a two stroke (which just happened to be a KTM as well). I like that 300 and will keep it. Its fun, cheap and reliable. But its time for me to get another thumper. I've been looking at my options. KTM seems to have a reliable 450xcw now that gets stupidly good reviews with no reported problems with reliability. KTM also has the 350, which I hear is the perfect size bike. Then there is the wr450. Its newer, better, and still super reliable (or so I've read). Problem is... the WR is advertised as 20lbs heavier than the KTM bikes. That is a lot. But its also about $2K cheaper. Has anyone ridden the wr and the 450xcw and compared them in the real world? Will I really notice the weight of the WR over the KTM? I'm mainly concerned about the technical and rocky trails. At speed, I probably would like the extra weight. Any real world advice is appreciated.
