I have a gipro gear indicator on mine. It is red lights and I am mostly happy with it. I have it mounted behind the left speaker grill and I can see it pretty well. My only gripe is that if the clutch is pulled in the indicator goes blank. Nothing major...just annoying.

I would REALLY like to have a 6th gear on this bike as well. Its got plenty of power. It would definitely be nice to see the rpm a bit lower at interstate cruise speed
