Both are different wheels.

One is the Sportmax/XXR 513 (or some number, it's on teh XXR website)

The other is either a Watanabe or a Rota, they both have models of wheel that look pretty much identical.

Could be either Watanabe F8 or Rota RKR. It's hard to tell at that angle of the photo.

They weigh ~7.5kg each from memory.

I'm sure Google will tell you though.
