Got one, and it fits perfectly in the battery box under the seat, in fact the 5mm extra height takes up the slack left by the old, compressed grommets under the securing bracket. The old YTX9BS rattled a little.
However the new battery cost almost twice as much. I reckon the extra capacity can only come from larger lead plates and the new battery is 2lbs heavier, so a couple of quid's more lead. 
Never mind, I hope this change puts the Kawasaki into the same long stand-by period as the Yamaha, which I've been able to maintain. I'll be back to commuting soon anyway, so neither bike will rest for long. Nov-Feb 2020-2021 will be the test, when I only use the bikes on occasional weekends. If this battery fails a lithium iron phosphate battery will be next, and as I understand it, won't blow my balls off or torch the bike like older Li-ion batteries might have. |
LiFePO4 chemistry is safe, 3+ years running now on the cbr and it's been left for weeks at a time lately and fires up immediately. Never been charged or maintained, 4kg weight saving approximately.
They're not all that expensive, about £90 for a normal bike but about £20 more for higher capacity, e.g.
