ER70 seems to be the first one to mention the "weight" of these bikes. IMO they are all too heavy. 300 lbs is too heavy for a 250 cc dual sport.
There is no reason for them to weigh over 270 lbs.
Why did Yamaha bother with the pretty aluminum frame, if not to save weight?
And the Honda is 320 lbs? How many 450s can you think of that weigh that much?
I hear folks talking about how well the WR250 handles the slab, going 65 mph for hours & hours.... I love riding small dual sports, but not for miles of interstate riding. Then again, I live in the middle of the mountains, surrounded by the Pisgah & Cherokee NF's, so I guess I have a different perspective.
