WHAT IS SUPER MAGNUM DOT/Novelty?
Raw classic appeal meets no-nonsense function in our Super Magnum Jet Helmet. What sets it apart? Our compact shell design has a unique cheek-hugging shape. It wraps your skull tightly while creating a slim, sharp profile you won't find on standard buckets.
This helmet throws a solid punch of vintage character while matching perfectly with your machine and gear. Add a shield or vintage goggles to switch up your look based on your mood or riding conditions. With its compact build, open-air feel, and custom options, the Super Magnum turns every ride into something worth talking about.
