There’s quite a bit of literature being disseminated that riders must wear CE-certified motorcycle clothing while riding. This is false. Depending on the country or region you live in, there are minimum requirements of what you are legally obligated to wear (likely only a helmet, a pair of boots or gloves, if even that), but the rest is up to you. This is, however, likely to change in the nearby future.
With the EN 17092 standard being harmonized, it means that clothing sold in stores with the purpose of being used while motorcycling do comply with specific requirements. Because, as mentioned, clothing that looks like it’s geared toward riding must actually reflect it in the worst-case scenario situation.
What you choose to wear while riding is (still) your choice. No one is forcing you to wear CE-certified garments. Please also note that clothing developed before 2018 did not have to be compliant, so you will still find plenty of garments at your favourite dealership that does not have the appropriate labels inside. That does not necessarily mean the garment isn’t safe. It just has never been submitted to certification. But, in our experience, and in your best interest, we absolutely recommend that you wear the maximum protection you can atop your bike. You owe that to yourself and your loved ones.
Note: legislation regarding CE certified motorcycle clothing is constantly evolving. Always check the regulations in the country you will be riding to make sure you are compliant with local/regional laws regarding motorcycle clothing.
