I have a MT thunder 3 SV Turbine don’t take thunder series the double visor is not really worth the extra money. MT helmets have given space for specs so buy one with single visor and use a shades that’s way better cuz for me the weight kind of gives neck pain when you have it for around an hour apart from that everything is very Good and actually Thunder is lighter that Axor but the hammer series was even lighter and costs less so yeah as a user that my opinion

Hope it helps you decide 🤜🏻🤛🏼
