Sissybar is custom medium low, OEM part no 51477-06. Great product. After taking the pics I also installed the custom tapered luggage rack (53953-06) which adds nicely to the rear end.
When it comes to the tallboy seat, I'm not satisfied with it. Sure, I'm 6 ft 7, so I need to stretch out, but the seat's extra height puts the rider too high in the saddle. Air over the windscreen goes straight into my face. The worst thing, however: The goofy riding position gives you really poor contact with the bike. The tank feels a mile away, and the original handlebar as well. You more like sit on top of the bike than across it, and it adversely affects my joy in curves.
In fact, I have just ordered a passenger pillion to the original seat, and prefer to use that. For my legs, I go for an engine guard with stretch-out highweay pegs.
And finally, the tallboy seat's finish is really cheap, thin and flat vinyl more at home on a budget Honda.
Don't buy it.
