SMK Allterra Bulldozer GL153 Off Road Motorcycle Helmet

The SMK Allterra Bulldozer GL153 is a dedicated off-road and motocross motorcycle helmet developed for riders tackling dirt tracks, trails and adventure terrain. The Allterra platform uses SMK's Energy Impact Resistant Thermoplastic shell construction together with a multi-density EPS impact liner. Its motocross-focused configuration includes an adjustable multi-position peak that can be positioned according to riding conditions and removed when required. An extra-wide eye opening is designed to accommodate compatible motocross goggles while maintaining good peripheral visibility. The helmet uses a Double-D ring retention system with a padded chin strap to provide a secure fit during active riding. Ventilation is an important part of the Allterra design, with multiple air intakes, internal airflow channels and exhaust outlets helping move air through the helmet during demanding rides. Inside, breathable and hypoallergenic padding uses moisture-management fabric and can be removed and washed, making maintenance easier after dusty or wet riding conditions. The Allterra is designed specifically for motocross, trail and off-road riding rather than conventional visor-equipped road use. This Bulldozer GL153 version features a distinctive Gloss White, Blue and Red graphic. Your Autonity inventory corresponds specifically to the Large size variant, providing an MX-focused option for riders seeking protective coverage, ventilation and goggle compatibility.
