| Martin,
I had a Sargent seat on my st4s and thought it was miles better than standard, and though i frequently talk out of my arse, on this occasion my arse agrees.
Having sold the st4s i do have a Ducati Performance high screen for sale.
I'm 6'3" it worked way better for me than the standard screen. Cost £65, yours for £30+postage if you want it.
U2U if interested. |
