My car racing helmet, much as I am in love with it, does not provide enough peripheral vision for safe street riding. Hotter'n'hell here in TX so ventilation is critical. Looking at Snell 2010 Bell Stars for @$300 ($600 retail) on sale. I found a NIB Snell 2005 Bell for $200 What else to consider ? Need to stay under $500. THNX.
