Boony, you’re kinda right, but also kinda wrong. The WR is lighter as well as faster. I know you are sick of hearing it, but trust me, there is a HUGE difference!
Now, I’m not a DRZ basher, I loved mine and they are a great bike. But, they are heavy, there is no two ways about it. And even more than the amount of weight is the way the DRZ carries its weight, making it feel heavy.
If there is any one advance in new bikes (like the Why Zee) that is ground-breaking, I think it is the way/location the weight is carried. Lower the fuel tank, change the angle of the head, whatever, but they are on to something. Exciting stuff!
