Rims and Kick Start

I just came across this picture and I was wondering if somebody can tell me where I could order those kind of rims for my bike or how they are called so I can start a search.

I am also wondering how that (looks like selfmade) kickstart might work. If I see it right the cover of the clutch is off and a lever is attached to it.

Thats the thing, doesnt look like its original to me. Maybe an engine I dont know but the Morini or KTM50 look different. This looks more like homemade. I was wondering if it would be possible to simply use a lever on the clutch nut if that would work to kickstart it. I dont give a damn if the cover is missing. I used to drive around without when I had the crappy Centrifugal Clutch. It looks like only the small wheel is protected with something and the area where the small and big wheel meet.

Edit: I just got an answer in the page in FB where I saw this that those rims are from motorcycles.

Just edited the last post. I dont think its still worth it for me since I want to get a bigger engine anyways.

But hey, tell me about inventing things. I just repaired my disk brake with two 10 cent coins because I was unable to find the brake pads anywhere and my new coaster brake just broke again...
