So the std battery is a YTZ10S with key figures being
weight 3.2kg
Capacity 9.1 AH
CCA 190
So to select a Lithium equivalent we should aim to match or beat the CCA rating to ensure a stress free ignition. Capacity is not so important unless you are going to draw any juice without the motor (alternator) running for more than a few minutes.
Common brands listed with MT-09 compatibility are:
JMT YTZ10S-FP
weight 0.9kg
Capacity 4 AH
CCA 240
Shorai LFX19 "A"
weight 1.12kg
Capacity 19 AH
CCA 285
But I am wondering how low dare you go ... you can get a smaller, cheaper battery, but the CCA is the really critical number and I would reckon close to the lead acid 190 needs to be target.
I would suggest the comfortable limit for maximum weight savings might be
JMT YT9B-BS
weight 0.6kg
Capacity 3 AH
CCA 180
The main caveat with Lithium is cold ambient temperatures - if you're riding in sub-zero through the winter you need to be mindful of reduced battery performance.
