The ideal motorcycle helmet for ADV touring needs to be lightweight and vent well. Youll probably also like a shade over a broad visor for better visibility on a trail. I tested the KLIM Krios Pro last spring and summer to figure out how well it balances those needs. Its a super-versatile helmet that’s bomber for almost everything you’ll throw at it.

　　In short: The KLIM Krios Pro ($750) motorcycle helmet nailed all my wants for a great ADV helmet: Its lighter than most others Ive tested. The integration of Koroyd — an energy-absorbing core — increases breathability. The peak, also known as a visor, is removable without tools, visibility is excellent, and the visor is photochromic, so it lightens or darkens for ambient light.

　　(Photo/Michael Frank) KLIM Krios Pro Motorcycle Helmet Review I tested this motorcycle helmet on a trail system while riding a 250 Kawasaki. I also rode a few longer routes with ride partners in conditions ranging from downpours to broiling humidity. Those experiences cemented my conclusion that the Krios Pro offers a superb blend of design elements that nearly ticks the list of ADV needs.

　　I prefer a helmet with breathability and an enlarged eye port. Fortunately, the KLIM cut an oversized visor opening. The brand revised the lid’s mouth vent to mimic what you find on MX helmets, so it’s enormous and allows airflow.

　　Even when I was sweating, the Transitions photochromic lens remained fog-free, aided by a Pinlock inner lens. The helmet also comes with a standard clear visor. And if goggles are your default for off-roading, the Krios Pro is designed to ditch the visor, and a pair of goggles fits easily in the front.

　　(Photo/Michael Frank) Tool-Free Adjustments The Krios Pro isn’t as loud as other peaked helmets Ive tested at 60 mph, but it’s noticeably less noisy, minus the peak. And removing it doesn’t require tools: Two knobbed screws thread into either side of the visor, and a third one anchors the visor at the crown of the helmet.

　　It’ll take a few practice sessions to nail the process. But once you do, you can swap visors, or lose or add the peak during any gas stop. 

　　I also appreciated that the brow and mouth vents have ergonomic controls. In my experience, they could be more easily snapped open or shut mid-ride, which I often utilized while riding double track to help keep dust out while breathing hard.

　　(Photo/Michael Frank) KLIM Helmet: Honeycomb Protects Cools After a harrowing ride that lasted several hours through the pelting rain, my neck and shoulders still didn’t ache, thanks to this helmet being weighing slightly less than others Ive worn. The credit partially goes to the Koroyd construction: a material inside the helmet with thousands of tiny hexagons that form a honeycomb core.

　　This material helps make the Krios Pro lighter and easier to wear over long miles. There’s less mass and more air in the innards. This honeycomb core is designed to deform in a crash while dissipating energy during that impact. 

　　Koroyd also vents very well, especially at higher speeds. No lid can help when you’re crawling at 5 mph plying doubletrack in the humid Eastern U.S., so I did get sweaty during really slow off-road sections. Otherwise, this design is very well-vented, including when I was moving more than 30 mph, even on hotter days.

　　(Photo/Michael Frank) Fidlock Chin Strap A Fidlock chin strap has a self-locating magnetic clasp, replacing a traditional double D-ring thats hard to thread with gloves. With gloves on, the buckle automatically snaps shut. Opening the buckle is just as quick. You just yank on the tether and pull. I wish I had this detail on every helmet I use.

　　(Photo/Michael Frank) Critique: Could Be Quieter Because ADV helmets have max venting, a big eye port, plus a peak, there tends to be more noise. If you want a super-quiet lid, it will have a smaller eye opening, minimal mouth venting, and a chin curtain that will seal off the air penetration between your neck and the bottom of the helmet. If you ride pavement and at highway speeds most of the time, thats a good call.

　　The Krios Pros mission is much more diverse, and the result is that its a bit louder. That oversized mouth vent pulls in a lot of air for off-roading. The peak generates some wind drone, although it is angled to sufficiently reduce the lift effect some peaks cause. 

　　One critique: In my testing, the visor didn’t seal tightly enough to prevent a higher-pitched howl from cutting through that opening at highway speeds.

　　(Photo/Michael Frank) KLIM Krios Pro Motorcycle Helmet: Conclusion The Krios Pros weight could be game-changing for most buyers. But the benefits of the peak, easy-breathing mouth port, broad lens, and excellent clarity via a light-reactive photochromic Transitions lens, and Koroyd core all add up to a superb, protective package. 

　　There’s no perfect ADV helmet. But KLIM is giving a great deal right here. The Krios Pro should make the shortlist of almost any ADV rider.
