I am modifying a 1980 Cx500 custom and would like to relocate the battery. What is the smallest battery that I can use that will still work properly with the motorcycle?

thanks for your help.

I thought this was the "Bandit" from Spain... where Y'at there Bandido?



I'll follow this as I'm wondering about going to something other than a wet battery. Some of the "Gel Cell and Mat batteries, Lithium Polymer and others are getting smaller, lighter and can be positioned in any orientation as they won't leak sulphuric acid all over the swing arm pivot




I'm just not sure about small AGM batts start current delivery capability or the damage done to lithium and other new tech batts under the extreme current draw of starting. there are some off the shelf options. All of these are oriented to "cold cranking amperage" specs... http://www.super-b.com/



If we just push start or someone figures out a kick starter conversion (has this been done?) for the transverse twin bikes... we could convert to led lighting and use a small burglar alarm batt.

from my experience the battery is barely enough to power the bike as it is. i went with a glasmat and mounted it on its side on top of the A frame of the swing arm. i took some 1/8" strap bent it to L's and welded to the swing arm then strapped the battery to it. i was going to open up the top of the swing arm opening but i couldnt get my grinder in there and a shop press didn't open it up. theres only about 1/16th" difference between the battery width and the swingarm body.

Not to hijack, but what are the options for folks sticking with stock location / battery size, but want to beef up their juice? Mine's getting old and I'm thinking of going the sealed route.

I purchased one of those MotoBatts. Seems to crank up pretty well and is virtually stock size. 2 year warranty too I believe. I think others may not like it but so far so good for me. It is sealed so orientation is not a factor, just in case you decide to tip it sideways later.
