Hi, I have a six year old Shorai that starts my FJR-AE easily through our riding season and had no issues at all. I normally put the bike to sleep at the beginning of December and don't do anything special like removing the batter, it's just has a motorcycle cover over the bike. Normally give it a one day trickle charge in February then usually uncover the bike in April and it fires up every year. We have temps here down in the -12c and summer highs in the 30c range, never had starting issues. Also had a Honda ST1300 with a Shorai lithium battery on it for 4 years (when I sold it gave the new owner the expensive charger with it!) so would recommend the Shorai even though they are pricey compared with most other types and brands. Oh, don't think it makes any difference but they are a fraction of the weight and size of a normal lead-acid battery, fits in the battery location easily with the rubber packing strips that come with the new battery.
