The Troy Lee Designs SE4 helmet was once the company's flagship for head protection with a style and fit that quickly become popular among dirt bike riders.
Though the new Troy Lee SE5 helmet offers the next generation of innovation, the SE4 remains a widely sought-after riding helmet which Troy Lee Designs continues to manufacture. Considered a moderately priced dirt bike helmet with high-end safety features the Troy Lee SE4 offers the acclaimed MIPS brain protection system, an innovative venting network and built-in comfort for all head sizes and shapes.
So how does it measure up on the track? Or trails? How about both.
MotoSport employee Ryan Forbes wears a 2021 Troy Lee Designs SE4 Polyacrylite helmet which he uses for track and trail riding on his 2016 Kawasaki KX250F. The SE4 comes in the mid-range composite shell, high-end carbon fiber or the budget friendly polyacrylate, a sturdy plastic material which is a bit heavier than composite or carbon fiber. All three models use MIPS with similar safety and comfort features.
The DOT-certified Troy Lee Designs SE4 Polyacrylite Helmet weighs 1500 grams and has 16 intake ports with six rear exhaust ports for optimal cooling. Forbes' head measures 23 inches so he wears a size large and confirmed a true-to-size fit for an intermediate oval head shape. He previously owned the Colorway edition but now wears the Strike and had this review for a gear-on throttle-rolled experience of the Troy Lee Designs SE4 Polyacrylite helmet:
Pros of the Troy Lee Designs SE4 Polyacrylite Helmet
- Good ventilation without over-the-top visual venting that distracts from the style and look
- Quality material liner and comfort
- Pretty weightless and a snug fit while riding
Cons of the Troy Lee Designs SE4 Polyacrylite Helmet
- A little bummed it didn't come with a second visor like the composite or carbon. Only reason being is this is kind of a cool paint scheme
- I've never been sold on the liner snap system. TLD has a notch and slide style which is a little tough at times when the cheek pad has three of them to line up and slide lock into place at once
- Chin bar seems a little close when first entering the helmet, but after the goggles are on and you're riding it's almost unnoticeable
Forbes described the Troy Lee SE4 as a good choice for the beginner and intermediate dirt bike and ATV rider looking for a quality helmet without emptying their bank account.
