Then they discovered that vehicle manufactures demanded torx fasteners and drivers that would lend themself to automated assembly and increased tool life, so they came up with the tight fitting torx plus sized fasteners and bits.

Harley was right in there with GM and Ford and started using the cost saving torx plus fasteners and tools to assemble their bikes....only problem is Harley never told us harley riders who twist their own wrenches that their torx fasteners required slightly different tools........HD will sell you their proper tools at inflated prices, but they don't reveal who makes the tools and provide you with the little bit of info you need to make proper tool selections yourself at a cheaper price.
