Welcome to the forum. Burger King?
Congrats. I recommend changing the seat first and then deciding if you need risers. The riding position of the Corbin made me think the bars needed to be 6 inched closer. I'm glad I got to sit on a bike with a Corbin to know it was not for me. I like my Sargent seat with the stock bars.
Hey, Mister, ..... is that motorcycle fast?It is truly, by far, the most insane fast motorcycle I have ever owned. It is heavy but it corners like it is on rails and the power delivery is simply stupid. The seating position is as close to perfect as can be but the fact that I am the windshield, gets old fast on long rides, otherwise it is one incredible machine.
