How about a ktm 400?? vs. the 300 and 525?

The 400 exc is a awesome trail bike. The 525 is a lot heavier so it would not work as well in tight woods but it would go faster on the street. The 300 is a two stroke so its a different animal than the two other bikes. The 300 is the best trail bike ever. I would not convert the 300 to a street bike. Go to ktmtalk.com and read post from riders who have these bikes. its a free site. Also mention the year model of the bikes your looking at.
