2017 Boulevard C90 Boss
 

Hello
New to Suzuki and the Boulevard.
Picked up a 2017 C90 Boss and finding it difficult to find parts/accessories.
my first question is handlebars.
how much can the stock cables be extended?
Am thinking ust risers for now, if I were to add 4-6 inch risers,, would stock cables be okay?
second is the sissybar/back rest. 300ish seems a bit much for the cobra or suzuki. Do the older C90 sissy bars fit (2012 - older)? Or C50 ones fit?
does not seem like the dimensions changed at all but most the ebat sissy bars say 05-12,
Thanks for the advice
