Troy Lee Designs - SE4 Carbon Streamline Helmet

Troy Lee Designs has been crafting premium helmets for over thirty years. All of that experience has resulted in the new line of SE4 dirt bike helmets. They have found a way to improve upon their award winning helmet, with the Troy Lee Designs SE4 Carbon Streamline Helmet. It is the perfect blend of comfort, design and protection that riders have come to expect from Troy Lee Design helmets. The SE4 Carbon Streamline has a few new tricks up its sleeve, while retaining all the same features that made its predecessor such a great helmet.


The very first thing that riders will notice about this helmet is how light it is. Due to the carbon fiber shell construction, the Troy Lee Designs SE4 Carbon Streamline Helmet weighs less than three pounds! Don’t be fooled by the light weight though. The carbon fiber shell on this motocross helmet is extremely strong and provides more than enough head protection for riders. It has received DOT, ECE and Snell protection certification as a testament to its protective capabilities. In addition to the light carbon shell, this motocross helmet is lined with EPS impact foam. This layer helps absorb impacts and mitigate the entire helmet while keeping it as light as possible. Sandwiched right between these two layers is the Mips protection system. For the uninitiated, Mips is a revolutionary helmet technology that seeks to prevent serious head injuries from rotational impacts. Mips dirt bike helmets contains a low friction layer that allows the exterior shell to slide relative to the direction of impact. This affords better protection against angular impacts.


Besides the double layer shell, the Troy Lee Designs SE4 Carbon Streamline helmet has a few other built in safety features. TLD has ramped up the amount of EPS foam in certain areas to provide more protection. The cheek pads feature emergency release tabs so emergency crews can administer medical support more quickly to injured riders. This is a dangerous sport and sometimes a few seconds can make all the difference. The visor on this dirt bike helmet is designed to break away to prevent further head and neck injuries in a spill.


When considering a dirt bike helmet, comfort is second only to protection. Often times, riders are forced to choose a protective helmet or a comfortable one. With the Troy Lee Designs SE4 Carbon Streamline Helmet, riders get the full package. This motocross helmet has so many comfort features that riders won’t want to take it off! The helmet is designed to keep riders from overheating while they maneuver around the track. The combined 21 intake and exhaust ports work to bring in cool air while dispensing the out air out the back. The exceptional airflow allows the moisture wicking liner to do its job as well. The liner pulls moisture away from the skin and hair and into the fabric where it can evaporate with the help of the air vents. All in all, The Troy Lee Designs SE4 Carbon Streamline Helmet is masterful blend of protection and comfort that riders will love.
