In my years of ogling over bike builds, I can’t say I’ve ever seen a sportbike with a custom made frame. I’ve seen plenty of choppers and bobbers fitted with fabricated tube-frames, or stock frames paired with hard-tail rear sections, but this streetfighter is the first time I’ve seen a modern bike with a 1-off aluminium frame hugging the driveline. There is some discussion within the thread regarding the choice of material and techniques for building the frame. I’m not qualified to comment on that stuff, all I know is it’s fun to watch things being fabricated from metal!
