Had a look through. It's mostly adding notes.
Section 2 Mirrors Un bodied vehicles. Time constrained element removed (whatever that was )
Section 4 Speedometers. Note saying GPS not a suitable substitute.
Section 6 Lighting. 3 wheeled mopeds rear lights max height corrected to 1500mm
Section 8 External Projections - Un bodied. Ball end levers may have a flat or be hollow on the bottom of the ball.
Bodied. Slight wording change re-hub centres/hub caps.
Section !5 Tyres. Note added re- DOT marking only acceptable if weight and speed ratings are also present.
Think that's it. But if you are building for MSVA, download the latest version and read it yourself.
