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.

An interesting post and well researched, but 300-500g difference over stock. Sorry, but have I missed something? For example, a performance exhaust will save you about 2kgs.

looks like a 2.3kg saving to me; 3.2 - 0.9

Having said that I wouldn't bother until the original battery is knackered.

I'll probably eat less pies and save weight!
Yeah, trying that to. :lol: :p
but the problem is I can't do what I call the "Be-Less" diet (pun entirely intended):
No Beer, no Bread, no Bacon, no Butter. I like my food, especially if it begins with "B"

Lead acid charger

It's good that the new type Lithium batteries don't need a special charger....now the standard lead acid charger works.
