What's your preferred engine size?

I've mostly ridden liter bikes for the last 35 years and haven't ever felt a lack of power. They've been airhead beemers and then the last eight or nine years 850 and 950 LeMans. I've ridden the BMW R65 and they had plenty of power solo, and even toured on the R80G/S. I like them all, but prefer the liter bikes. They're big enough the wind doesn't push them around and powerful enough to climb most hills in fourth if not fifth without slowing down, and no problem passing when I want.
