Only 718lbs, lol. Riding in the rain, not for me, I'll be one of those fair weather/recerational riders, and rely on my other vehicle for rain.
+40# of fuel ("in running order" means with oil, filter, brake fluid, etc., but with only a splash, if any, fuel in it) = ~760#.
There are 2 of us at my house, and we have 2 cars, 1 SUV, 1 truck, and a bike. If you put any miles on, especially in the PNW, you WILL ride in the rain. With this bike, you will really want to rely on your car for the lion's share of your rain riding, though, because as I said, they're seriously not great in the rain. I'm not sure why they even put bias ply tires on anything any more, given the leaps and bounds that radials have made in the last 20 years (they were better than bias plys when they came out, and they're ~3-4 generations better than they were even in 2003-2004)...
It's obvious that your mind is made up, for whatever reason, and you don't have to justify it to me or anybody else. You can't ever justify an hobby, anyway... Having said that, you live in a GREAT place to RIDE in the mountains, and I'd really hate to see you pick a bike that's best suited to cruising in northern Indiana or Iowa, without riding anything else. I mean, if you just want to do poker runs, bar-hop, and putt around, they really are good for that. Please, please, please, at least ride a modern American, Japanese, or European "standard" type bike or 3, before you throw down that kind of cash on something that's going to be a real hinderence if you find out that you like RIDING rather than CRUISING. If you just want "american", then the Buell Lightning or Ulysses are great bikes (the latter being the more comfortable of the 2). And if you do end up buying the Switchback, PLEASE PLEASE PLEASE get the ABS model! I'm serious about bias plys sucking in the rain, and ABS is about the best way to at least somewhat combat that in a panic stop, especially if you get caught in the start of a rain and all the oil from the road is floating at the top.
