The Nitro N501 Apex Analog Chameleon full-face motorcycle helmet is an affordable, adaptable helmet with a surprising array of features. It offers a custom-designed multi-poly tech (MPT) constructed shell with a sophisticated ventilation system with a twin top vent with twin integrated rear exhaust ports, an easy open chin vent, and a rear spoiler to not only add airflow but aerodynamics. An integrated chin wind curtain is a highly convenient addition, with a fully removable colour-coded soft touch liner and cheek pads for optimum comfort. The micro-metric retention chin strap is fully adjustable for the perfect fit and security, and the N501 is ECE22.06 certified. The anti-scratch clear visor also features a DVS internal sun visor system, which is ultra-easy to use and highly useful!
