I put 16th in front on my bike (need to use new-gen sprocket cover). Really mellows out freeway driving. Do have to downshift 1 or 2-gears for passing sometimes, though.

Hey Danno!
Did you use stock chain on the 16 toofer
New gen sprocket cover is strictly bolt on?
As always thank you for the wisdom
