All 1500 Goldwing (exept Interstate model) have reverse.

Why do you need motorcycle battery? Use only automotive.

"Am running a 16 at the moment with a car tyre" What car tire are you use now?

I have #51 battery in the box on the frame between bike and sidecar.

Yes you are. We all are.

Velorex 562 and it is good price.

why? do you have any problems?

Any liguid cooled / shaft drive, solid steel frame will be best. Any other will be good too. Sidecar is fun.

Do not have wheel. It use 165r15 (165/80r15) tire.

Welcome. I have same sidecar on 96 Goldwing. Love it.

25-28 GL1500/FRENDSHIP III depend of load and speed. Pushins lot of air.

What bike do you have now? It can be big enoght to attach sidecar. Big bike w/ sidecar is not a best idea for biginer.

DVD player .

I ad 5th mount on 79 Suzuki gs550/Velorex. No more flexing.
