I'd consider a half helmet. They're light and you can hear your engine better if you don't have any noisier mods. The only downside is some loss of protection including your ears and little bugs getting in them. Considering this a bandana or balaclava works well. Maybe neoprene face mask in the winter. For gloves hardware stores often carry thermal/water proof work gloves so you can try them in store and they're not too expensive.
