IE: The 2008-2010 models?
A shopper on Aug 10, 2011
BEST ANSWER: Unfortunately, no. Both the liner and the cheekpads have changed for the Vector 2.
Hi. I just purchased an Arai Vector 2 in a size L. Will changing the helmet liner from the factory one give me anymore room in the helmet? Understanding the helmet is brand new, it still feels too small in the crown.
