Arai Motorcycle Helmets

As an authorised UK Arai dealer and Stockist for over 30 years, our store has a fully trained Arai helmet specialist who personally measures, adjusts, and professionally tailor fits your helmet. As one of the few Arai technicians in the UK with this depth of legacy training, this fitting service is available at the point of purchase in our Boston, UK retail shop J and B Motorcycles.
Because premium helmets naturally loosen over time, we provide dedicated ongoing care for your unique Arai—personally adjusting your lid with genuine Arai technical foams and servicing your helmet every six months to support its 5-year warranty. Every premium helmet we stock is handmade by Arai in Japan. With up to five shell sizes, five cheek sizes, and five skull liner variants, there are 125 standard configurations—alongside near-infinite custom fitting possibilities using specialised Arai foams to guarantee an uncompromised fit. Buy with confidence from the UK’s trusted Arai specialists.
