DescriptionThe whole story▼
Triple-certified and built on Just1's latest J-STR safety platform, the J-STR Titan in Red / Blue / Black Matte delivers the kind of protection that serious street and sport riders demand — without compromise on comfort or style. The aggressive matte multicolour graphic is purpose-designed for streetfighter, naked, and sportbike riders who want a helmet that looks as purposeful as it rides.
Key Features
- ECE 22.06, DOT, and CCC certified — meets the most current international safety standards for road and track use
- ABS outer shell manufactured in two shell sizes for a precise, proportionate fit across the full size run
- EPS inner shell in two densities / sizes for optimised impact energy management
- J.I.E.R. Emergency Cheek Pads Removal System — enables first responders to remove the helmet safely without aggravating a potential neck injury
- Double-D retaining ring — the trusted, race-proven buckle system for a secure, repeatable fit every ride
- Protx2 antibacterial and odour-inhibiting liner — fully removable and machine washable
- Wide Vision visor with scratch-resistant coating and Pinlock 70 preparation (Pinlock lens sold separately)
Safety First — Built on the J-STR Platform
The J-STR Titan earns its ECE 22.06 certification — the most stringent version of the European standard — alongside concurrent DOT and CCC approval, making it legally compliant across Europe, North America, and Asia. The two-piece ABS shell architecture means smaller sizes are not simply squeezed into an oversized shell; each shell is sized to maintain consistent wall thickness and impact geometry. The same logic applies to the EPS liner, where a dedicated size ensures the foam's energy-absorption characteristics are tuned to the actual head it is protecting. The J.I.E.R. system adds a further layer of real-world safety: cheek pads can be extracted rapidly by emergency personnel using the pull tabs, reducing the risk of secondary injury during helmet removal at the scene of an accident.
Comfort and Interior
Long-distance comfort comes from the Protx2-treated interior. The antibacterial treatment suppresses the bacteria responsible for odour build-up, keeping the liner fresher for longer between washes. When a wash is due, the entire interior — cheek pads and crown liner — pulls clear of the shell in moments and can go straight into the machine. Ergonomically contoured cheek pads hold the face securely without pressure points, and the ventilation system circulates fresh air through the helmet to manage heat on spirited road rides.
Visor and Equipment
The Wide Vision visor opens a broad, distortion-free field of view that is especially valuable in fast, dynamic riding situations. The scratch-resistant coating protects optical clarity through everyday use, while the Pinlock 70-ready insert pins allow the optional Pinlock anti-fog lens to be fitted without modification. A nose cover comes supplied in the box to reduce turbulence and buffeting at speed. A helmet bag is also included to protect the shell in storage and transport.
Sizing Guide
Measure your head circumference with a tape measure placed just above the eyebrows and over the ears — this is the widest point. Repeat the measurement once to confirm accuracy. Choose the size that corresponds to your measurement in the table below. The helmet should sit firmly on the head with even, all-round contact; if it moves under gentle side-to-side pressure, size down.
| Size | Head circumference (cm) | Inches |
|---|---|---|
| XS | 53–54 | 20.9 – 21.3 |
| S | 55–56 | 21.7 – 22.1 |
| M | 57–58 | 22.4 – 22.8 |
| L | 59–60 | 23.2 – 23.6 |
| XL | 61–62 | 24.0 – 24.4 |
| XXL | 63 | 24.8 – 25.2 |
