Within the HJC RPHA family we find the ST range, helmets designed for maximum comfort on the go for the tourism-sports sector.
HJC is the manufacturer that sells the greatest variety of helmet models, with 21 different models. Having so many models means betting on all the helmet lines that the market requires, therefore within the brand’s range, we find full face, modular, jet, off-road and high range helmets known as RPHA
The RPHA (Revolutionary Performance Helmet Advantage) family offers very lightweight helmets, with excellent aerodynamics and whose shell is made of a mix of fibreglass, Aramids, carbon fibre and organic non-woven fabric, as well as other features.
This article centres on the ST range of the RPHA family, which as its name indicates, are helmets designed for “sport-touring” use. This means that it is a helmet range that places special emphasis on noise insulation, providing maximum ventilation (adjustable) and other options so that our bike trips are more comfortable. This range clearly has its sights set on the SHOEI GT-Air, another sport-touring helmet with similar lines and that places sets comfort on the go and noise reduction above weight and aerodynamics.
Starting with the shell, we find that this has been designed in three different sizes: The smallest for sizes XS and S, the medium one for sizes M and L and the largest one for sizes XL and XXl.
As regards the interiors, these are in SilverCoolPlus, a system that drains the inner humidity and is odourless with sliver antibacterial fabric. The interior is completely detachable and washable. The inner moulded foam allows for the use of normal or sun glasses.
The ST range also has an integrated solar visor, with an easily removed smoked visor, that can be operated with gloves. As regards the screen (HJ-20ST), this is anti -scratch, anti UV, with
(the anti-fog visor is included in the helmet) and has a RapidFire system for replacing the screen (a simple ratchet mechanism that facilitates the mounting/removal of the visor easily and quickly, without tools). The screen also has an automatic opening and closing system via a spring control lever, operable with gloves.
The ST ventilation has a variable air inlet, also easily operated with gloves.
The RPHA ST weighs approximately 1350 grammes, has the safest fastening system of the market (double buckle) and is marketed in sizes from XS up to XXL. Also, it has a five year guarantee.
