That looks like similar to the one on the TZ250(A) above but with some differences in nose shape and side trimming.
The first street TZ/TR I saw had an RD400 motor in a TZ twin shock frame but no fairing and in some ways it looked more aggressive than one with a fairing. It was so simple. My first RD was also an RD400 stuck into a TD3 frame with a horrible set of mismatched parts on it.
I have also repaired and rebuilt a couple of RD based TD3 racers with a mix of original and replica parts. One used a fairing similar to that one but in two pieces - nose cone and belly/sides. That bike was mostly TZ250 twin shock with a TD3 top end and RD front end.
That one had TZ/RD wheels and a GT750 rear brake cable to go with the Vesco longer oval tube swingarm that I swapped for his OEM rectangular swingarm.
