From experience:

Bring the sales invoice of the helmet (clearly stated the model and price date purchase) from MY sourced seller.

Then Find the Custom booth in point of Departure, (KLIA or KLIA2) Ask them to record the helmet show the invoice and get the receipt (form) of acknowledgement that the helmet indeed for personal use.

This brings to the problem if your flight is during odd hours then chances the kastam booth is closed, you might need to go to the arrival section and speak with the kastam officers who manned the arrival checkpoint for this helmet registration.
