Plus an older bike as well. My second bike was a Vulcan 750 with a 3.6 gal tank. I never got the MPG on that bike as I do on my new bike.
On the 750 I did have a Petcock to manually switch over for reserve. On the Vulcan S it is more like many new bikes where there is no manual Petcock. Instead the last bar or E on the gas gauge starts to flash when into the reserve. I was surprised how far I could go on that last bar before it started flashing... and then to know now I can go about another 40+ miles when it does. On that ride it started flashing with a little more than 12 miles before I stopped for gas. That makes it a little more than 45 miles on reserve!
