I could see the benefits of using Arch just so almost every function my system has is near-perfectly documented in Arch Wiki.
That is literally the main reason I started using it - over time I kept running across helpful Arch wiki articles while looking for info on stuff so when I got a new computer I figured I might as well go with Arch.
Adding a bunch of unsprung weight is a poor decision when it comes to handling though, and that’s something pretty important in a motorbike that’s trying to do more than just low speed commuting. Such a design will also be putting a lot of vibration through the motor components which is not good for longevity. It’s more a case of going for the (admittedly distinctive) aesthetic rather than being sensible.
