Wondering if anyone out there is using the Cobra sissy bar made for the 1300. I'm switching my bike over to a quick-detach sissy bar configuration and have the yamaha brackets already. I like the look/height of the cobra round sissy bar and the associated backrest pad better than the OEM from yamaha but would like to know the measurements on the holes to see if it would bolt right up or if I would need to do a modification to make it work. Thanks for any info/suggestions.
