I like both bikes. Having owned a WR400 in the past and ridden the newer 450's more recently though I have to admit to sharing the same opinion as the Cycle World shootout noted above . The 450 just doesn't FEEL any lighter then the 650 in the woods, despite being lighter "on paper". It seems to get compared to the 650 instead of the other 450's that are along for a ride. And the motor feels like a 125 compared to the grunt of the BRP. I like the WR but it is not a "lightweight" alternative to a 650R. The 450's magic button IS nice though, but of course unlike my old WR400, the Honda actually starts!
