Yup, but when you're out in the wilderness without a clue and the batteries or the entire device die, it sure would be nice to have that old fashioned compass and map as a backup. I keep wondering what the younger generation would do if a sudden huge EMP were to kill all the electronic devices in the world and shut down all the satellites. I have a feeling the result would be both extremely funny initially, and then extremely sad when everything shuts down and people start dying because they have no clue how to do anything the "old fashioned way". God forbid we have to live in a world without instant and constant connectivity, and an "app" to tell us what to do.

Oh yea...I still keep a compass for the "just in case" situations that are inevitable if you do any wandering around in the woods. And I still like looking at a good map spread out in front of me instead of a 3" screen...I like to get the "big picture" in my head that only a paper map can provide, even when traveling on the bike. But then, I'm a map freak of sorts anyway. I'm getting old, so don't go out for days at a time like I used to, but you can bet your azz I'm going to have a topo map and a compass as a backup, regardless.
In 20 years, people will be as lost as farts in a whirlwind without electronic devices....

Back on topic: I've had three different HD bikes in recent years...a '06 SEUC, '06 SEVROD, and the '11 SERGU, and admit to having all three of them up to speeds equal to or exceeding 110mph, though not for long periods of time, and they were all as steady as a rock. But, none of them had stock suspension either...having your front wheel making constant contact with the pavement is a good thing at those speeds, and the stock front end on a HD does NOT keep the front tire on the ground as much as you think it does if there are any irregularities in the road surface.
