They are made by Wild Kart which is Italian manufacturer. Parts are simple and easy to get since they are made by Wild Kart, if you google it they are a couple importers here in the USA. Karts don’t have suspension by the way. It is a J32 and it includes everything listed on the website chassis, bodywork, front and rear torsion bars, decal kit, seat, etc. It is brand new and I still have it wrapped up in the original box it came in from Italy. You can probably get a better idea by going on the website and looking at the details of the kart. Honestly I have never seen a more beautiful kart when it comes to the finish and quality of the components. I’m looking to get $4000 or any reasonable offer close to that. If you look them up the chassis goes for $6250.00 anywhere else. Feel free to ask me any other questions you might have. Chris
