If the battery is dead and you push start it, you may still be stuck. I had a cbr that the battery failed and I pushed started it in 2nd. But the bike couldn't charge the battery fast enough to run the digital dash and stock electronics on the bike. I had to park the bike and call AAA.15 months and still fine with no battery tender - even though I believe it's a 12 month battery. I can bump start the bike so a dead battery shouldn't ever strand me.
+1 for a battery tender over the winter or long storage periods will help keep your battery fresh and ready to go.Going on year and bike still starts. Always use a battery tender over the winter months.
Don't confuse a LiFePO4 with a lithium ion battery....two different animals. The LiFePO4 CAN be charged with a regular battery charger (battery tender type) just as long as it DOESN'T have a desulferization mode built into it. It would also not go past 14.4 volts while charging. The LiFePO4 also does very well being stored in a cold environment and is not susceptible the the battery "venting" or exploding if over charged like a lithium ion battery. Shelf life discharge is very low also, without needing to be on a tender over the winter months. I just bought a Ballistic brand LiFePO4 for my Zuma pit bike and cost was almost identical to a quality gel cell battery.lithium ion requires a special charger (ask me how I know that's not a theory), they are also more effected by cold temperatures than standard batteries. had one in the SV rated for a V6 car, in the winter getting the bike started before the battery died was still a fight. with the fz being FI hopefully that's not a problem with this bike
