After 5 yrs when it slows down some I'll pay another $60 and get 5 more years of solid starting.

when these batteries evolve to 1/2 their current price and do better in the cold, i'll look again. until then it's a solid working and proven AGM for me.
yup there are tolls to pay besides $$$ to successfully use LiFePO4 batteries in adventure bikes. which are the most demanding of all motorcycle applications.

one year in with Shorai LFX 36 in R80G/S ... has proven itself up to task of supporting an adventure bike. When lithium batteries are sized with enough amp hours. they have proven themselves very rugged and reliable. but it's not for everyone...

this is why for most folks AGM is still the way to go. unless of course you are part of that group where saving 10lb or so is worth it.
