that is unnecessary.
I see no reason why this battery wouldn't work.They'll run two sealed beam lights for about an hour or so while doing their job as emergency lights,and after restoring power,they recharge quickly.The short time starting the motor,followed by charging by the alternator,should quickly recharge it.This would work even better with kick start. lhanot sure, I put a 2.8 amp hr alarm battery on mine
would this battery fit in the xs400? 220CCA of sealed AGM power vs the stock 165CCA!!
Cost is $72 shipped vs stock $54.81(shipped with acid)
Length: 5 1/4"

I beleive the extra $18 is worth never having to kickstart my bike.
