Steve,

There is no specific rule on how or where it needs to be secured, but if the transponder falls off for any reason the rider won't be scored.

The only reason for manual scoring in this race is in the event of a transponder technical failure, not lost off the bike.

In the event of a crash the crashed rider is to remain with the bike and be picked up by the MRA crash crew. The bike will then go back through tech before it's allowed back on the track. Once the bike is back in the pits (as transported by the crash crew) then the transponder can be exchanged to another team members bike and they can continue racing.
