I just went out and looked at my left foot peg, again (Interceptor). Yup, still out at an angle, but not as bad as Mr. TEC's.
Then, with it on the center stand, I pushed down on the left foot peg. It sprung inward a bit.
Then I swung a leg over and pumped both pegs (still on ridged center stand). Both foot levers moved a bit and sprung back.
So, that cast foot peg mount that we tend to complain about (me included) are actually a designed-in comfort point by absorbing road shock. (?)
