My garage has a slope into it and reversing the bike in is a bit of a pain.
Driving in is even worse as I have to do a 15 point turn to get the bike facing out!
A turntable is what’s needed.
I bought a “Lazy Susan” bearing from Bangood that is 300mm diameter and with a loading of 450kg.
To that I bolted a 5mm thick disk of aluminium. Total thickness is 15mm so its not too hard to get the bike up in the centre stand. Total cost was about €25

The turntable in use.
