This is a good looking motorcycle bike helmet!
Thanks!

How effective are motorcycle helmets? (DOT ECE SNELL)
Compared with cars, motorcycles are an especially dangerous form of travel. The federal government estimates that per mile traveled, the number of deaths on motorcycles in 2006 was about 35 times the number in cars. Motorcyclist deaths have been rising in recent years — more than doubling by 2007 from the record low in 1997. In 2007, more motorcyclists died in crashes than in any year since the National Highway Traffic Safety Administration (NHTSA) began collecting these fatal crash data.
In contrast, passenger vehicle occupant deaths reached a record low in 2007. Motorcycles often have excessive performance capabilities, including especially rapid acceleration and high top speeds. They are less stable than cars in emergency braking and less visible to other motorists. Motorcyclists are more prone to crash injuries than car occupants because motorcycles are unenclosed, leaving riders vulnerable to contact with hard road surfaces. This is why wearing a helmet, as well as other protective clothing, is so important. Helmets are the principal countermeasure for reducing crash-related head injuries, the leading cause of death among unhelmeted riders.
How effective are helmets?
Helmets decrease the severity of head injuries, the likelihood of death, and the overall cost of medical care. They are designed to cushion and protect riders' heads from the impact of a crash. Just like safety belts in cars, helmets cannot provide total protection against head injury or death, but they do reduce the incidence of both.
NHTSA estimates that motorcycle helmets reduce the likelihood of crash fatality by 37 percent.2 Norvell and Cummings found a 39 percent reduction in the risk of death after adjusting for age, gender, and seat position. Helmets are highly effective in preventing brain injuries, which often require extensive treatment and may result in lifelong disability. In the event of a crash, unhelmeted motorcyclists are three times more likely than helmeted riders to suffer traumatic brain injuries.
While no real-world crash studies have yet evaluated the effectiveness of novelty helmets, or helmets that do not meet federal performance standards in preventing injury or death, recent NHTSA laboratory tests suggest that head injuries are much more likely with these helmets than with ones certified to the US Department of Transportation standard.
