Sorry don't know how that translates to MPG, but essentially I get about 230-250 km per tankful (including the reserve), depending on whether mostly city or highway riding. So that works out to 143-155 miles per tankful in your antique measuring system.
Hope that helps...

"Antique measuring system"? I heard that

Actually our measuring system is newer than the metric one...but metrics do make more sense...anyway...
As for Jon's question, our antique answer will be more helpful because he will have an antique speedo and antique gas pumps to fill up the tank. You'll get about 60 mpg with the stock bike, or as he says, about 135 miles to a tank.
I get about 110 miles before reserve, and it is good for about 25 additional miles*.
