It's all no-name stuff, save for the KKE wheels, which are maybe on par with Tusk wheels, which are probably in the tools-worth-buying-from-Harbor-Freight kind of quality category. Stark and Alta were using components you'd see on Japanese and Austrian flagship models, KYB, WP, Brembo, etc. Stark might be building their own wheels, but Alta was using Warp 9 Elite series and those are pretty good, definitely above Tusk and maybe a hair behind OEM.
This is a really scary bike to pay $11k for. Just a few months ago Kawasaki was blowing out their '23 KX450's for $5995, which is a really good bike that won 450 shootouts, and I guarantee that if you paid $5995 for a new KX450 and $5995 for a new Arctic Leopard E-XE 880 and rode them both all the time, the quality of the Artic Leopard would be disappointing in comparison. Can't imagine paying nearly double for it.
The guys in the video kinda suck, imo, for hyping it up the way they did. There's no way that guy does 60-70mi guided tours for people while riding a '24 KTM XC and is excited over a new $11k dirt bike from China with no recognizable components. He pulls out a 2000w charger with an xt90 on it and doesn't laugh? C'mon.
