Looks like a bug (the problem ist the setting of 'xpd').
What you can do is:
At first substract 50 from your data, then add the axis manually:
x <- seq(50,100,10) # your data
xn <- x - 50 # substract 50
barplot(xn, yaxt="n") # no axis (would be wrong)
axis(2, at=0:5 * 10, labels=5:10 * 10) # so adding it manually
