The LS2 FF345 Strobe is a modular (flip-up) motorcycle helmet that is part of the LS2 lineup of affordable yet feature-rich helmets. It's often praised for offering the convenience of a modular design at a very competitive price point.

Here's a breakdown of its key product features:

Design and Shell

• Modular (Flip-Up) Design: The main feature of the Strobe is its chin bar that can be flipped up, allowing the rider to easily eat, drink, or talk without removing the helmet. It uses a full-metal latch system for a secure and smooth operation.

• Shell Material: The helmet shell is constructed using LS2's High-Pressure Thermoplastic Technology (HPTT), which is a mix of ABS and other thermoplastic polymers. This makes the helmet relatively lightweight while still providing good impact protection.

• Safety Certifications: The LS2 Strobe FF345 meets or exceeds ECE 22.05 and DOT FMVSS 218 safety standards. It's also worth noting that the UK's SHARP safety test for the FF325 version of the Strobe gave it a 3-star rating and, importantly, noted that the chin bar remained locked in 100% of impacts, which is a great result for a modular helmet.

Visor System

• Twin Shield System: The Strobe features LS2's "Twin Shield System," which consists of a clear main visor and an integrated, drop-down sun visor.

• Main Visor: The main face shield is made from "A-Class" polycarbonate, which is optically correct, scratch-resistant, and UV-resistant. It's also Pinlock-ready, though the anti-fog Pinlock insert is typically sold separately. The visor uses a quick-release system for easy changing.

• Drop-Down Sun Visor: The internal sun visor is operated by a slider on the side of the helmet. This is a highly convenient feature for riders dealing with changing light conditions, and the "analog" slider mechanism allows for partial adjustment.

Comfort and Fit

• Interior Liner: The interior liner is made from a breathable, moisture-wicking, and hypoallergenic fabric. The entire liner is fully removable and washable, which helps keep the helmet fresh over time.

• Fit: The helmet's fit is generally described as an "intermediate oval" shape, which is common. Some users, however, have noted that the sizing can run small, recommending that riders try one size up from their usual to get a comfortable fit. The cheek pads are 3D laser-cut for a more secure and comfortable fit.

• Ventilation: The FF345 Strobe has a dynamic flow-through ventilation system with adjustable intake ports on the chin and top of the helmet, along with exhaust ports to create a constant flow of air. While this system works to keep the rider cool, some reviews have noted that it can be noisy at higher speeds.
