It's an RG140, probably from 1987 (should have a silver sticker with 'F7xxxxx'). Guitars from 1987 often had a mixture of Roadstar and modern RG features, so catalogues aren't always reliable. Date also supported by lack of serial on neck plate, still MIJ (later ones were MIK), modern headstock (on Proline only in 1986), scratchplate more like a Strat's on bass side.
Here's a 140 from the '86 catalogue.
1987, though still has Power Rocker.
One close to yours (this is a 1987 too, but have seen an '86 with the same specs), but vintage trem, Super 7F single coils, and Roadstar headstock.
