The sleek 270g Limar Air Star reminded us of Michael Knight’s car in Knight Rider, but it’s night riding where Limar’s latest seeks an edge over the competition, with the rear retention ratchet turning into a three-mode rear light at the touch of a button.
It’s a simple but effective aid, even if it isn’t USB-rechargeable (it’s easily removeable if you want to shave 10g). The Air Speed, which sits above the Air Star in Limar’s Revolution range, has scored very highly in our own wind-tunnel tests and the latter would be one of our picks for sub-£100 aerodynamics.
There are more ventilated helmets here, but we’re a sucker for a chin pad and the outer red shell covering the EPS foam is slickly done.
Verdict: Smart, light and aero benefits, but could be more vented.
