SO, I have a modded XR400 (that I paid $2500 for) in current dual sport trim. I have a top speed of around 93 mph with 16/45 gearing and I get there quite quickly. I have the opportunity of purchasing a WR400 that has been dual sported for $2700. So, even though I like my XR and it works for me, I am always looking to upgrade. My question is, is the WR400 a significant upgrade? Will it be more exciting or reliable? Also, I understand the WR makes more HP, but how much torque does it have in comparison to the XR4?
