Riders backrest


Not sure if this is the right place to post this, but here goes.

I have seen a few bikes, Goldwings, Harleys, a Vulcan and a Volusa with a riders backrest.
As was planning on going to Mandela Del Lario this year ( lockdown scuppered that) it strikes me that a riders backrest might be a good idea and make the trip more comfortable. Fingers crossed I get to go next year.
Is anybody aware of a supplier of riders backrest that will fit a 98 Cali EV, preferably UK based?

Thanks in advance


Forgot to add mine has the 2 seats, I know there are some with one piece seats
