Flip front (also referred to as flip-up or modular) helmets are approved to either the P (Protective) or P/J for double homologation (Protective/Jet).
When a helmet has P homologation it is not possible to use it while keeping the chin guard open and it must remain closed.
For P/J homologation, you are allowed to ride with the chin guard in the open position or even without it entirely if it's modular.
POR means Professional Off-Road. A POR tyre can be legally driven on the road, as POR tyres do not fall within the scope of the EU tyre label Regulation 1222/2009 and are confirmed in UN Regulation 117.
The EU Tyre Labelling Directive (Regulation (EC) No 1222/2009) states that POR tyres do not fall within the scope of Regulation (EC) No 1222/2009 on tyre labelling. The reason for this is that POR tyres are specifically designed to achieve exceptional adhesion performance under poor conditions and in all areas, which prevents them from meeting legal thresholds and significant grading levels.
UN Economic Commission for Europe (UNEVE) Regulation No 117 "Uniform provisions concerning the approval of tyres with regard to rolling sound emissions and/or wet grip and/or rolling resistance [2016/1350]" states that POR tyres are excluded from EU Tyre Label Regulation 1222/2009.
A tyre's ply rating (PR for short) is a numerical index that quantifies its load-bearing capacity of the tyre. Higher PR numbers signify greater strength and durability.
Helmets with PINLOCK® visors or compatibility, PINLOCK® prepared visor means easy and convenient fitment of the PINLOCK® fog free lens system.
