One of my cars was a 66 VW Beetle with 50 hp, and it took myself and my new wife halfway across the USA and back. And you need what to go down the freeway? On two wheels? That VW Beetle had a 1600cc engine. With 50 hp. And what do you "need"?
When I looked at my current bike, I considered the weight. I like to take pictures to share where I've been. But I knew with the bike I had at 570 lbs, I'd already passed up numerous stops simply because of the weight. And the bike you're considering is easily a hundred pounds more.
I've been riding a bike with a wet weight of 470 lbs. for the last several years and 66,000 miles. I've never really considered another bike for those trips. And you are looking at a bike 200 lbs more?!?!?!?!
Why?
