Dear Blue Rider, i will check and clear the problem on my website,
I am not surprised that the model available in Singapore are cheaper, they sell only Discount model from previous year.
I am sure that if you order the model you want through the singapore Dealer, the price will not be 400 SGD.
It is the same in Thailand, we have a lot of helmets at Discount price ( starting at 5999 baht net, for a RSF3, up to 11 999 baht net for a RSR2 Carbon) , and we have also the 2011 collection at full price (between 11 000 bath to 28 000 baht net ).
If you want to see our whole collection ,you can always try our facebook account : sharkhelmetsthailand
