Verified Customer Reviews for HJC RPHA 31

Friendly, helpful staff.

Narrowed my selection down to this RPHA 31 or an LS Infinity Carbon. The LS2 was not showing stock however for a couple of months so went for the HJC. The small helmet size has always fitted before so went for the same, snug around the head but very tight around the cheeks initially, especially when the visor is fully shut, the sides narrow and was a little uncomfortable. The cheek pads are removable and are standard 35mm. You can put in the ones from the XXL size helmet which are 25mm thick, however I could not find these anywhere in the UK and to get from abroad you had to spend £135. So I tried the medium but this was just too big so going to persevere, I'm sure it'll give. Also I ride with the visor up most of the time so not a major issue. The staff were always very helpful and understanding whilst I was dithering. Pleased with the snug fit and level of comfort, glasses fit without any discomfort. Little pricey when compared with the LS2 but overall pleased.
