If you're in the middle of nowhere in the state of Washington state I'm sure there will be a hill near by, just bump start it. In all the electric
start bikes I've owned, TE511, TE610, KLX650, I've never had an issue with the electric start not working. 15 Yrs and never even replaced a starter.
I wouldn't worry about it.
I killed the battery on my 610 by leaving my grip heaters on all night. Wouldn't bump start for love nor money, even though it's a carb'd model.
I was in the desert and there was one hill nearby. We towed it up the hill and I tried to bump it all the way down. No go. About a year later my started failed and I had to purchase another one. I now have 3 keys for my bike instead of an already-stupid 2.
I carry a tiny little set of jumper cables now.
