Define "lightweight":
I think that Husaberg has me beat by 75 lbs even before my luggage.
He's might have you by more than that. Mine is 233 dry, and it only holds 2.4 gallons of gas and about 3.7 drops of oil. The Husaberg is the lightest bike I have -- and I've got a couple of small (<250cc) trail bikes.
But, the 'berg is a bit high strung for an 'adventure bike', IMO. Sure, it's a hell of a lot of fun, but I consider mine more of a toy than anything. In fact, I wouldn't want to live off of my Husaberg for more than one night. Hell, I think I'd rather take *any* of my other bikes on a longer trip (including the CM-400 rat bike).
The Husaberg just isn't the right bike for it, IMO. The bikes handle so damn good, I can't bring myself to load it down and kill the performance (also, I can't get myself to slow down and enjoy the scenery when I'm riding it :bike_rider: ). The Husaberg is too much of a 'dirt bike with plates'.
But hey - that's just my opinion, based on my travel style, and what I like / don't like. If someone else thinks differently, that's cool. Because in the end, we all know that the 'best' bike out there is - you guessed it: The one between your butt and the ground.
