This By City Xtreme review considers a fibreglass full-face helmet with a drop-down sun visor and double-D retention. Its two-shell specification and removable interior give useful starting points for a fitting, while the prepared outer visor needs an equipment check before ordering an insert.

Visor equipment and interior fit
The injected outer visor is listed as ready for a pinned anti-fog insert. The checked package includes a carry bag, but does not establish that an insert is supplied. Confirm the exact compatible insert separately and check clearance around your glasses when lowering the internal sun visor.
The shell contains multi-density protection, with ventilation openings intended to channel air through the helmet. Try the controls while wearing gloves and check pad contact with the strap fastened. Follow the care instructions for removing and washing the lining; the stated shell material alone does not establish comfort or noise levels.
Protection and construction
The listed approval is ECE 22.06. Check the exact helmet label and specification for the version you are buying, particularly if you need it for a track event.
Fit and adjustment
The chin-strap fastening is Double-D. Make sure you are comfortable operating that fastening and adjusting it securely before choosing the helmet.
Comfort and everyday use
The interior is removable for cleaning. Follow the manufacturer’s care instructions and refit the pads in their original positions.
