Can't be comfortable riding position 
"Rider comfort" sits pretty low on the list of requirements for motorcycle LSR racing.

Rollie Free, 13 September 1848. Record 150.313mph on a Vincent wearing only a rubber bathing cap, Speedo trunks and borrowed tennis shoes.

And ol' Burt carried a burn scar on his leg due to the leg laying on an exhaust pipe during one of his LSR record attempts piloting his Indian streamliner.
Tough guy didn't back down just because he wasn't
comfy. [smiley=thumbup.gif]
