No, what the OP is looking for is a fiberglass piece that makes the Ninjette swing arm look like a supersport casting, combined with a hugger.
I had one on my bike, from Sportisi Moto. Company still exists but they're not importing body parts anymore.
Looking back, I wouldn't do it again. Purely a cosmetic thing and it didn't fit all that well. The hugger part did serve a purpose but the swingarm cover was just pointless.
Just FYI... back in the 90s all supersport swing arms looked like the Ninjette's. We didn't have fancy castings back then.
