Just to share my experience purchasing helmet online, I bought Scorpion EXO R1 Carbon Air from Champion Helmets. Communication with them will be somewhat slow but still reliable. Need to constantly wait and scout for promotion to get best deal but I got it for around EU 340 (RM 1600) including extra gold visor which I think it's a very good deal.

Delivery to MY reached in less than 2 weeks at Pg POS branch and were held by custom. Maybe it's my luck but they only request me to pay tax (10% - RM 160) and using POS as my agent (RM 48). After payment of tax and agent fee to POS, I waited for roughly a week for the helmet to delivered to my home.

Total cost around RM 1,800. At Motoworld, it cost RM 2300 (not including gold visor).
