https://utpr.com/Is going to use my seat to fabricate a driver's backrest for the V-1000. (I'm using "driver" on purpose to signify rider and not passenger)
They have one for the 650 but have not done one for the 1000, which they found strange since this bike has been around for awhile now!
I had their driver's backrest on my triump trophy and loved it.
They're giving me a deal on shipping in return for the inconvenience of being without the seat for about a week. They need the seat to fabricate the mounting hardware. Normally they send you the kit and you install yourself.
The backrests are adjustable up, down, forward and back.
Here is a pic of the backrest on the V-650...

I'll keep you posted...
