2025 Troy Lee Designs Helmets - Range Updates
When buying a new helmet, weight, comfort, ventilation, and style all come second to protection, but if you're choosing from the 2025 Troy Lee Designs helmet lineup then you've pretty much got it all, let’s break it down. Most notably, the 2025 launch sees the departure of the SE4 helmet which has been superseded by the GP Pro, an affordable, safety conscious helmet with a Polyacrylite Shell and the MIPs C-Solution system. In Australia, helmets now need to meet ECE 22.06 standards, this is the most recent update to these standards since the early 2000s, which alone means helmets are safer. Helmets are now tested in realistic scenarios for low and high speed impacts, as well as rotational testing because most crashes in moto don't just incur direct impact.
GP
The GP is the most affordable helmet in the range, it features a polyacrylite shell which is a lightweight, impact-resistant plastic that performs best in low-speed crashes, making it common in entry-level helmets. Beneath the shell, a 3-piece single-density EPS is optimised for impact absorption based on its placement within the helmet, for example thicker foam in high-impact zones and less EPS to reduce weight in sections of less stress. However, being single-density, it doesn’t absorb energy as effectively across a wide range of speeds like dual-density EPS, it’s generally tuned for either high or low speeds. There are 4 shell sizes shared across two helmet sizes: Youth M/L, XS/S, M/L, XL/XXL.
GP Pro
The foundation of this helmet is much the same as the GP, but it gets one all-important addition... Mips. If your first thought is "why should I care?" Or better yet, "why should my pocket become lighter only to add Mips?" Mips is a low friction layer between the helmet liner and EPS, it provides an extra 10-15mm of movement which is substantial when it comes to protecting your brain. Ever hear of the Meninges? This is a layer that acts as a shock absorber protecting your brain from trauma, Mips is essentially the helmet version of this designed to minimise brain injury from rotational forces, so yes it’s worth it, don’t overlook the value of a rotational management system in a moto helmet. The GP Pro is also upgraded with moisture-wicking cheek pads. The GP and GP Pro helmets are the only helmets in this range available in youth sizing.
SE5 Composite
On debut, the SE5 helmet was the first to feature the Mips Integra system, a slip-plane for rotational energy management which is seamlessly integrated into the inner eps layer, helping decrease weight and increase air-flow. SE5 helmets feature dual-density EPS split into 3 sections of varying density for the right protection where you need it most. By combining low and high-density EPS the helmets provide more progressive impact absorption, reducing forces across a range of crash intensities.
SE5 Carbon
The main feature that splits the SE5 Carbon from the Composite helmet is shell material. Carbon fibre is strong and more rigid so it spreads impact over a large surface area, it’s most well known feature is how light it is, but it also outperforms fiberglass helmets in extreme crash scenarios. SE5 Carbon is upgraded with a Ionic+ liner for moisture wicking and lightweight titanium D-rings. In the box you'll find a premium zipper helmet bag and a spare visor. The SE5 Carbon helmet weighs in at 1160g, and outperforms the rest of the range for its lightweight high-speed impact protection.
