Engineered for the demands of modern riders, the TT-Revo Sport Touring helmet seamlessly combines cutting-edge aerodynamics with uncompromising safety. Whether you are navigating urban commutes or embarking on long-distance tours, this helmet delivers superior airflow, structural integrity, and all-day comfort. Premium Engineering & Specifications Next-Generation Safety (Homologation): Ride with complete confidence. The TT-Revo is fully compliant with the latest ECE 22.06 and ISI safety standards, offering rigorously tested impact protection. ADT-Advanced Shell Construction: The outer shell is constructed from ADT-advanced thermoplastic—a proprietary blend of highly crash-resistant thermoplastic resins. It is manufactured across three outer shell sizes (M & L molds) to guarantee a low-profile, proportional fit. Dynamic Airflow Ventilation: Temperature regulation is managed by precision-cut channeling within the internal polystyrene. It works in perfect symbiosis with five front air intakes and four rear extractors positioned under the aerodynamic spoiler, ensuring rapid exhaustion of hot air and optimal interior cooling. High-Fidelity Optics: Equipped with a scratch-resistant polycarbonate visor featuring a secure locking system for high-speed stability. The innovative tool-less quick-release mechanism allows for rapid visor changes, and the system is fully PINLOCK® ready for optimal anti-fog performance. Advanced Interior Comfort: The inner lining utilizes a breathable, bi-elastic fabric woven with synthetic fibers for superior moisture-wicking and sweat absorption. The interior remains fresh and dry, while the cheek pads are fully removable and available in varying thicknesses for a customized fit. Track-Tested Retention: Fastened by a highly reliable, lightweight alloy Double D-Ring retention system for maximum security. Optimized Weight: Designed to minimize neck fatigue on long rides, tipping the scales at an optimized 1550g ± 50g (Note: Size S is engineered to approx. 1500g ± 50g).
