After looking at a few different type of bike helmets I bought an Arai Rapide Or today from the amazing Naps in Setagaya. It’s a really impressive shop, and has an massive range of items for all types of bikes from helmets and clothing to pretty much every spare part you can think of, and custom paint jobs. The staff were friendly too, and very helpful, offering some good advice, even if it meant you maybe didn’t buy the most expensive things they had.
