I want to use a smaller battery to save some space on a project SV. The bike is garaged and is not used daily so it's not a big issue if it has to sit on a trickle charge when not in use.
I have a small light 12v battery out of my KTM that fits nicely and started the bike fine in the past so wouldnt mind using something like this. I am not an electrical guru so want to know if using a smaller baterry (size) in my bike will have any adverse affects on the electrical components. Comments appreciated. Cheers, Grant |

I wouldnt have thought physical size would make any difference.
Liz's Ducati has as tiny battery compared to the battery on the SV or my GSXR, but its cold cranking power is much higher...

No, but (and it is a possible big but)
A small battery will tend to have less CCA, so the chill mornings when the bike needs more hoof to start because of the oil being heavier, tolerances nipped up, and the battery being cold... it won't have the reserve grunt. Also, the reduced Ah rating means it won't be able to crank it for as long, and will have less power in reserve if you end up with the engine off and the lights on. With the engine running, the battery acts more to smooth out the alternators delivery of power, it's the starting thing that will be hard work. SV is a challenge to build wierd stuff with as there's no space. Easy as pie on old gixxers because you can put all the electrics in the space where the old airbox used to be! Fizz, those ducatis well known for their electrical longivety? ![]()

What are you going to use it for? Commuting and leaving outside? Or a toy sat on an optimate?
P.s looking at your project photos it would look loads better with a beefier front end on and a fair jack up at the back. Handle loads better too!

Like the others say.
The Yuasa YTZ range have about the best cold cranking performance "bang for buck" of any battery at the moment. A YTZ-10S will certainly do the job, it's about the same size as a "standard" curvey battery but better CCA spec, I had one on my Deauville for years with no probs. They do a YTZ 7S with a CCA of 130A, compared to the 190A of the YTZ 10S . It might just about cope if you only use the bike in favourable conditions (not excessively cold and keep it fully charged etc). The 7 is a somewhat different shape format compared to the 10, 113x70x105 vs 150x87x93 , might be help or hindrance. I doubt very much anything less than 130A would like it much starting an SV650.

I ran a YTZ7 on the thunderbike and never had any problems spinning over the high comp motor, its slightly smaller than a ytx4, get a yuasa one though, not cheap, but cheapo ones dont giv the amps for as long and dont last very well
