Ruroc AT4.0 Track Nitro Helmet - Official Ruroc Sizing Station: Moto Central

The Ruroc AT4.0 Track Nitro helmet is the ultimate fusion of motorsport nostalgia and futuristic design, now available at Moto Central, your trusted Official Ruroc Sizing Station. The classic Ruroc ‘R’ pattern elegantly wraps around the back and sides, while vibrant neon flashes inject a high-speed energy into the design. As an Official Ruroc Sizing Station, Moto Central ensures you achieve the perfect fit for this striking helmet. Because Ruroc are generous, they're including two sets of custom stickers, allowing you to add your track numbers and truly make this helmet your own. The AT4.0 Track Nitro is Ruroc's fastest motorcycle helmet to date, rigorously tested and modified into a formidable track day weapon, achieving ACU Gold certification alongside DOT and ECE 22.06 approvals, making it fully legal for both road and track use. At Moto Central, our expert team provides precise sizing advice, ensuring your AT4.0 Track Nitro helmet fits perfectly for maximum safety and aerodynamic efficiency. While we proudly showcase this dynamic Nitro design, as Ruroc experts, we can order any colour and size variation within the AT4.0 Track range directly into our store, exclusively for our valued customers. Ride like you stole it, customise it like you own it, all with the perfect fit from your official Ruroc experts.

On the track is where the AT4.0 Track Nitro truly excels. With a 10% overall weight reduction compared to the standard AT4.0, you won't have to sacrifice protection to gain those vital extra seconds. An extended rear spoiler optimises airflow across both the helmet and rider, and the new capped side vents significantly reduce shuddering when coming out of a tucked position, ensuring your head remains steady. Years of refinement have resulted in a helmet that is lighter yet still capable of handling the demands of heavyweight track days. The sculpted design and smooth carbon shell minimise wind resistance. The track-approved DD chinstrap ensures compliance with track regulations. The integration of industry-leading RHEON™ protection technology provides exceptional defence against both direct and rotational impacts. A new upper visor seal prevents wind and moisture ingress, maintaining clear vision through the ultra-wide 215° peripheral and 100° vertical field of view. Enhance your focus by pairing your phone with the compatible Shockwave Bluetooth sound system (available separately). Trust Moto Central, your Official Ruroc Sizing Station, for the perfect fit and the ultimate track-ready helmet.
