Product review: AGV K5-S Darkstorm helmet

I tested this AGV K5-S Darkstorm helmet, red, (RRP £231.99) for one year, covering 10,000 miles.

Here's how I got on...

What’s good?

The AGV K5-S is advertised as a premium sports helmet and is packed full of neat little features. It is aesthetically pleasing, with its curved lines and aerodynamic design, and is made from a carbon and fibreglass mix with features such as a drop-down sun visor, integrated ventilation system, fully removable liner, Pinlock-ready visor, double-D strap and integrated rear spoiler. The biggest surprise is the weight, or lack of it.

Rated at 1550g (+/-50g), it sits nicely at motorway speeds with little buffeting and remains comfortable on my longer rides. The cheek pads are pressure-free for all-day riding and the visor can be removed without any tools for easy changes.

What’s not good?

It has nice touches but it’s flawed. The aperture is wide enough, but narrow from top to bottom. The liner is attached at the front of the helmet using Velcro, which can move and rub on my forehead.

Even with the supplied Pinlock insert, the visor mists up in cold weather and the internal sun shade doesn’t come down far enough, leaving a bright gap between itself and the bottom of the main visor. Also, the chin vent switch is very difficult to operate with a gloved hand.
