Has anyone ridden the new WR450 yet and what are your impressions. I had a 98 WR400, 01 WR250, 01 KTM 520 M/xc and was wondering how you think they compared to any of these or how you liked them. I like that they can finally be fairly quiet without too much loss of power and the e-start is nice but not necessary. I wish it had a 6-speed like some others but probably don't need it. Does it get decent gas mileage on a tank? Or would I be needing an IMS/Clarke tank for the longer hauls? I wonder if it does OK on a MX track too. Is it good in the rocks and nasty tight stuff too. Any actual weight claims too. Thanks for any comments.
