Just got my new Shoei helmet. What is the little tube of Silicone oil for? Does it go somewhere near the visor? Thanks.
Rub a small amount of it on the rubber trim where the visor seals to it, helps keep the rubber pliable and ensures a good airtight seal when closed and minimises any wind noise.
Apparently it's for the seal around the visor to keep it supple, as per the instructions I was wondering the same when my helmet arrived
