Since it was established in 1971, HJC has made nothing but helmets for motorcycle riders. This decision to concentrate on one product perhaps explains the worldwide success of the brand. Perhaps the ultra-modern research facility with its own wind tunnel also has something to do with it. The outstanding design and high manufacturing quality certainly play a part. In any event, the Korean company is one of the biggest helmet manufacturers in the world today. The top product line HJC RPHA bears comparison with the best helmets in the world. And what's more, they represent extremely good value for money!
