I just picked up my '00 FLSTC. I noticed on the dash, next to the "Engine" indicator is a "Pursuit" indicator. Do I have an old police bike? If so, it must've never been used on the force, 'cause it only has 20k miles for an 8 year old bike. Most police bikes I see have 50k+ miles in just a few years.
My 99 Heritage had the same thing and I bought the bike brand new. I was told it was in all the speedos but only lit up on the police bikes? It was difficult to see unless the sun was shining on it just right. Ignore it and it will go away.
