I've thought about swingarm. Obvious choice would be facelift one, but that's too obvious for me. Styling wise i think it's too bulky for a bike which is mostly about lightness. I've always loved Aprilia RS250 banana swingarm and this one has same kind of twist. I've heard it's stiffer than facelit version (but i have no facts about it). My personal choice would be Bursi/Febur/SBK one but that choice would make this bike to go over 10K€ so that worries me a bit too Trying to find out excuses not to do it... So the current one will stay until i go completely crazy with it. This bike is also everything about different kind of things which i've loved over the decades of bike ownerships. 2-1 exhaust is a reminder of 90's chimneys in all the cool bikes like Ducati supermono, ZX-7RR, ZXR and so on. For some it might look mismatch but that's how i like it. Other reasons are usually keeping the build stupid simple or save weight. There's currently one for sale... https://www.ebay.de/itm/30686286494...862864943|ni_bn:1&_trksid=p2380424.m570.l5997 IMA adjustable billet clipons are on the list too...
