I agree with Les. They look like NSR250R Magteks.
I don't believe the HRC wheels have "DOT" cast into them, as they are not road legal.
To be honest, I expect your instincts are correct anyway. Street Mg wheels feel heavy! (NSR250R Magteks are only about 500g lighter than Enkies.) You can "always" tell an HRC race wheel the moment you pick it up.
