In an issue of dirtwheels, I remember reading an article where they put a much better battery off of a CBR600 (sport-bike) into what I believe was a YFZ. Is there any good way to fit a better battery of any kind into a large utility bike, like a Rubicon for example?

 

You might can get another Rucicon batery and put it in the storage box and link them together to get twice the amps but still 12 volts, I know this can be done because the man on texes mudder sight did it and has pictures. Good luck!!!

 

Interesting. Thanks!
