The Race Star Flex DLX Rsd nutzt Bell's proprietäre Flex-Technologie, um das Gewicht zu reduzieren und gleichzeitig die strukturelle Steifigkeit durch eine mit Kohlefaser verstärkte Verbundschale zu gewährleisten. Die interne EPS-Auskleidung verfügt über Zonen mit variabler Dichte, die für die Absorption von Hochgeschwindigkeitsaufprallen optimiert sind, kombiniert mit einem integrierten Sonnenvisier und einem antibeschlagenen Belüftungssystem, das die thermische Dynamik bei aggressivem Kurvenverhalten steuert.
