'Bout a mile, but it was Tempe, AZ so it was flat, and it was a CB160 so it was light. Bad battery, went for too long of a ride at night with the lights on and it took a dump.
Pushed a 350F about a half mile, same conditions. Blown fuse.
** I should add: had to push my '64 Plymouth about 2/3 mile, by myself. It was flat and I ran out of gas (don't ask). Had to stop for a break, and about 50 feet from the gas station someone ran over and helped me get it in. I appreciated it, but I would have appreciated it more about a half mile away.
