One of the very basic principles of designing a new product (say, oh, a motorcycle) is that you use the simplest, most readily available parts possible, and you standardize. That means if you can get M6x1.0 bolts with a 10mm hex head cheaper than the same with a torx head, and you need 40 of them on a bike, you fucking use the hex head so long as it meets all of the requirements. It will save the company money, save the customer money, and be generally "better" in the long run. The whole bolt thing is just an example of one of my gripes with BMW. I'm not saying I refuse to buy one because of their fastener choice
And yet you don't understand the inherent benefit of a Torx head over a Hex...
My suggestion is not to be a DIY'er.
