Hi Richard,
I’m certainly not an expert but can provide some insight. If you’re in the Vancouver area I would go into some shops to figure out what helmets fit you best. Buy what works for you. I ride a BMW and have owned 2 in my 20 years of riding. I love the motorcycles. What kind of riding do you want to do? On/off road? Just on road touring? Everyone has a favourite but it really depends on what you plan on doing with the motorcycle.
High Road (Langley or Vancouver) have a good selection of gear and you may want to check them out – the stuff they offer is quality so you may pay a bit more… but what value do you put on safety?
You could attend a meeting (once the pandemic allows us to meet) and ask these questions.
Best wishes in your quest.
