Yes, a center stand attaches to the frame in the same way as most side kick stands, with a dished plate above the framework right behind the seat post and behind where the rear fender bolts to the frame. I don't know the name of that spot, but you know where I'm referring to. The dished plate has a hole in it for a bolt which sandwiches the frame members to each side and bolts on through to the stand, either a side kick stand or a center stand. The reason I like the center stand is that my bikes tend to get heavy above with engine and gas tank, controls, etc. and there is a greater tendency for the bike to tip over, especially with just one point of contact with the ground. If the ground is soft, that is bad news for either kind of stand, so the larger the points of contact, the better. Rear drop stands which attach near the axle on vintage bikes have a nice retro look to them, but are kind of a pain to keep clipped up while riding... probably why they were replaced with the handy and quick "kick stand" coming off to one side. When I was a boy it was uncool the use the stand at all... you got off the bike at a run and just dumped it on the ground. Girls used the kick stand. Manly type boys dumped it. Ha! Maybe that's one reason vintage boys bikes are so often beat up beyond recognition and girl's bike fifty years old look faded, but otherwise ready to ride.
