There are hundreds of helmets on the market. Baggers strives to showcase only the best and AGV’s Matt Black K-4 Evo ($219.95) definitely makes the cut. It blends top-quality construction, modern styling, comfort, and function all in one attractively priced package. The versatile K-4 is available in XS-XXL with a removable, machine-washable inner liner and interchangeable cheek pads for even more of a contoured fit. The outer shell is comprised of an Advanced Composite Fibre (ACF) shell construction that meets the strictest of safety standards and multiple vents do a pretty thorough job exhausting air out the rear extractors, keeping you cool on hot days. The Street 8 clear visor is made from durable polycarbonate and prevents fogging and resists scratches from taking over your line of sight. When you’re ready to give the visor a thorough cleaning, AGV incorporated a super user-friendly architecture known as the Extra Quick Release System (XQRS) for removing/installing the visor in a matter of seconds without any tools. As far as sliding the helmet on and off, some normal break-in time is necessary so that it’s not as restricting. Be patient, after about 10 uses the K-4 fits right as rain.
