I'm looking to fit a passenger back rest for my 2014 ST1300. I've got top box with back pad that mounts onto OE plate for two tours. Would like to get a stand alone rest for day trips ect.... when top box capacity and weight is not needed. Any advice would be welcome, I scanned the Forum but failed to find info - combination of age and technology I guess . Cheers from a hot & sunny spring morning in Cheshire.. Mike
