The Suzuki GS450 was really a 400 on steroids. In Japan, 400cc bikes are popular because they classify as medium size; go bigger than 400cc and you're in a more expensive tax class. But that line in the sand doesn't apply in the U.S., so Suzuki gave its little twin a CC boost to make it more appealing to U.S. buyers.
