Totally not being a smartass here... it is listed in your owner's manual.
I believe I had 1 & 1/2 qt leftover from the Vic oil change kit I got at the dealer when I did mine in January. But yes, the owner's manual will have your answer.
If this is the 1st oil change you've done on this bike yourself... be prepared, the drain plug is reallllly in there. But it will break free.
I use Victory oil. Works perfectly, no need to change to anything different when it works fine.
