SMK Allterra X-Sprint Off-Road Helmet

The SMK Allterra X-Sprint is a dedicated MX and off-road motorcycle helmet developed for riders who spend their time on motocross tracks, dirt trails and other demanding off-road terrain. SMK constructs the Allterra using two outer injected Energy Impact Resistant Thermoplastic shells, helping optimise safety, fit and comfort across the available helmet sizes. Its off-road configuration includes a prominent peak that can be easily removed or adjusted according to riding conditions and rider preference. An extra-wide eye opening is designed specifically to accommodate compatible MX goggles securely while providing a broad view of the track or trail. This makes the Allterra suitable for riding environments where dedicated off-road goggles are preferred over an integrated road-style visor. Ventilation is managed through a channelled system with multiple air vents and exhaust outlets, promoting continuous airflow during physically demanding riding. Inside, the hypoallergenic comfort liner incorporates anti-moisture management and antistatic properties to improve comfort during extended use. The liner is both removable and washable, making maintenance easier after dusty, muddy or high-intensity rides. This X-Sprint GL257 version features a Gloss Black, Blue and Orange graphic scheme, while the Medium inventory variant should be selected according to the rider's measured head circumference and SMK's official sizing guidance.
