In the 2009 MoM's For all disciplines.
12.8.5.1 – footrests must:
(a) Be well rounded and designed so as to ensure that no dangerous edges are created due to wear.
(b) Not touch the ground at lean unless they are hinged or pivoted and controlled by a return spring.
What about dangerous edges not due to wear … hope MA doesn’t look at some of the footpegs available as standard equipment as well as the aftermarket ones … there are some that would slice straight through to the bone ….
