I really don't think the influence was that big. It's just that Tokusatsu in general changed and Kamen Rider changed with it, rather than trying to stick with its basis.
In the early 80s, Super-1 already started introducing a large number of weapons/attacks with the multiple gloves and ZX had heavy chest armor and weapons (although only one or two, IIRC). Black went back to basics, but it was a direct attempt at restarting the franchise, just look at the story, which yet again returned to the modified human turning against the organization that created him and didn't feature ties to any previous series.
Metal Hero doesn't have exclusive use of large arsenals, look at Sentai shows too. Besides, Metal Hero, with its constant image changes that make Heisei Rider look like a perfectly consistent franchise, just lacked an identity. There's only so much influence something like that can be considered to have.
It supposedly was Ryuuki.
Ryuki eh? I wonder if there's a source for it?
