The HJC RPHA10 helmet is one of the top-of-the-range, race-spec motorcycle helmet from well-known motorcycle helmet manufacturer HJC – as worn by MotoGP rider Ben Spies.
On our own digital scale, the size-medium version weighs a super-light 1,342 grams. We're not sure why it's called the RPHA10, which we read as 'arf a ten', which could be slang for half a ten– why didn't HJC call it 'Five'?
Anyway, it has a 'Premium Integrated Matrix' shell, which is basically sandwich of carbon-fiber, fiberglass, organic fibers, aramid twill and polyethylene layers. It has a quick-release visor mechanism that is probably one of the best visor mechanisms you find on commercial available motorcycle helmets.
The ventilation of the HJC RPHA10 is variable adjustable by a very helpful and glove-friendly system on every individual ventilation intake. The chinstrap is D-ring type and the lining is made from advanced silver anti-bacterial fabric, of course, removable and washable. The inside of the HJC R-PHA10 is treated with Ginkgo extract, which comes from the Ginkgo biloba tree and is known for moisture-wicking and countermeasure for bad odor.
The color-scheme in the picture is the 'RPHA10 Ben Spies Monster Replica II' design, and there are five color-schemes in total and with the solid color-scheme you can choice from 6 colors (black, white, yellow, matte-black, silver, and anthracite).
