Arrived today from Japan, saved £200 on the UK retail price, very happy, love the helmet and the dealer was spot on. Now I need a tinted visor and dry weather
It doesn't need ACU.......It is Snell. M2010 and as stated below its good although I will be checking up on this to make certain. For the first time in years, they may be able to choose helmets which satisfy all the local regulations and provide a premium of protective capability over and above local requirements. Helmets certified to the M2010 standard and ECE 22-05 will provide protection comparable to M2005 and will qualify for sale and use in the UK and Europe.
Depends what you want it for I suppose. I take mine on the track and they state you must have an acu approved lid. Don't know how much it's policed but I'd hate to fork out for a track day and be told to go home.
Just reading an article about Arai, and they say they are the only helmet to exceed all international standards. If you do a track day, you could always take your old lid just in case.
I wouldn't wear my IOM lid on the track, I have an Arai chaser that has the gold sticker on so will be fine for the track
