The HJC IS-17 is constructed from an advanced polycarbonate shell which is lightweight, and thanks to the use of CAD technology offers a comfortable and superior fit.
The 'ACS' Advanced Channeling System gives full front to back airflow which flushes heat and humidity up and out of the helmet.
The HJC IS-17 also has a 'RapidFire' visor replacement system which allows quick, tool-less removal / replacement of the visor.
The HJC IS-17 is also Max Vision Pinlock ready.
The IS-17 uses a Double D strap system and also has a 3 stage tinted internal sun visor.
HJC has been designing & manufacturing high quality protective helmets since the early 1950s.
In the 1990s HJC became the American top selling motorcycle helmet - a position it has held ever since.
HJC's focus remains on building helmets of remarkably high quality, with extraordinarily generous specifications and at unbelievably reasonable prices.
