Bought a '04 KTM450EXC and wasn't all that impressed with the power. Seemed like I was always shifting trying to keep the revs up. I'm now looking at a host of bikes from a used '13 KTM500 for $7K (perfect condition) to a left over '13 YZ450F for $4.5K that I could spend the cold winter turning it into a street capable weapon. My question is... is it worth it? Or do I look for a WR? My concern is that the WR will be relatively close to the KTM's power delivery whereas the YZ will be nasty to the bone. There will be no WOT situations to worry about as most of the time will be spent on single track,dirt roads and windy back country roads. Are there parts and pieces available to convert the YZ... road legality is my main concern... and that it not look like some POS when I'm done.
