Arai isn't a firm that just bashes out new motorcycle helmet models. The incumbent top of the range helmet, the Arai RX-7 has been in service since 2008, so the new Arai RX-7V uses a new resin compound in the outer shell, called PB-SNC2, which improves the 'stick' between each layer, saving 30 grams in the process.
Ventilation is improved to the tune of 11 percent, with bigger switches better for quick access to the outside air. The visor system is all new, with a new locking function too, so no more gritting your teeth to take the old one off.
The new shape of the Arai RX-7V allows an extra 3mm of room in front of your face. The new liner is all washable, a traditional D-ring is your closure mechanism and the helmet comes with a five year warranty. Given making each shell can take 27 steps and that it takes 18 man hours to manufacture one helmet, it comes as no surprise to see its premium price.
But this is an Arai motorcycle helmet, and we've come to expect that of a product that really is the crowning achievement of this Japanese company. The price of the plain color helmet starts around 28,000 THB.
