Battery relocation for racing

I've searched the forum for this and can't find anything.

I've noticed that some minitwin race bikes have the battery relocated. Where exactly is it moved to? How is it done and why? (Weight distribution?) Is a smaller battery used?

Cheers

i would move it out of the bike and onto a shelf, then use a motogp bump starting lawn mover type thing

gotta be the easiest way to save a couple kg hasn't it?

I don't think you're allowed to do that in Bemsee minitwins. I think you can use a smaller battery though.

seriously though...

Some people move the battery down to the lower RHS of the bike. However it takes a hell of a lot of time moddin the loom, fabricating brackets and holders. Not really worth it. Buy a Steve Jordan rear subframe and you can retain the battery in the original position.

No major benefit.

Yeah as above, pointless moving the battery, just a load of work for nothing, plus down there it's more likely to get clobbered in an accident, the retention of the 'road' underseat plastic tray is no bad thing as you can keep the tilt switch at perfect 90 degrees and also give the ECU and electrics some protection from spray and debris. I think this mod is only been done because lazy subframe makers can't be bothered to consider the undertray or mounting points. The amount of lashed up horrors you see in the paddock is a worry !

I use a YTZ-7 battery and fit it on the rhs above the generator, its not much work to do and you can run a very minimal seat/subframe and it puts more weight towards the front, I did have some battery trays made up along with subframes. i'll see if I can get anymore done.
The loom on a curvy is just the right length to mount the cdi on the fairing bracket if looped round the back of the engine and everything else virtually falls in to place, Injected is similar but the ecu ends up under the tank and the tilt switch can be mounted on the tank bracket
