2002 Honda VTX 1800 C
My bike is an ‘02 1800CYou might want to post more information about your bike, what year, model ? C, S, R, N, F, T ?
For comparison, mine is a 2003 R and I typically get 40-42 MPG but I seldom ever check it. I put gas in mine pretty often so it's been a long time since I've let it get down to the low fuel light sensor but as I recall, it comes on in the neighborhood of 150 miles or so. When I hammer it, or when the wife is on with me and we have the bike loaded up, the mpg's will drop, 35 is the lowest I have ever seen. I don't have a fuel manager on my VTX anymore, but I did have a PCIII until 2017. I do have Vance & Hines exhausters, and a K&N air filter.
