I PASSED!

I have a feeling that a CZ 650cc motorcycle with sidecar did have a reverse gear that would also operate if the sidecar was removed

Interesting, I know my CZ 125 had no reverse gear, but it did have automatic gear change.

On the subject of three wheelers, you can ride a Piaggio MP3 125 or a Yamaha Tricity 300 on a UK car drivers licence (some older models still count as bikes and can't be ridden if you don't have a Motorbike licence though) apparently it's all down to the distance in width between the 2 wheels as to how it's classified.

I think that was an automatic clutch

The motorcycle with reverse is Russian URAL 650 commonly with a sidecar, which can have a driven wheel.
The CZ was a czechoslovakian made motorcycle whose gear lever folded back to become the kick start.

Well done you will now have to learn the art of double declutching
