Battery Tray

 
Dr. Bral gave me the idea to move the electrics from the subframe to a place "inside" the fuel tank a while ago.
The fuel tank has a large cavity above the carbs, where normally the airbox would be.
But as I've binned the airbox in favor of four separate K&N's it's just an empty space.
I did think about cutting the bulge away and fitting a plate instead to increase the fuel capacity dramatically, but if I put the electrics there it would allow for a much more simplified and generally "cleaner" look of the subframe.
As I wanted to change the seat position too I went for the option of relocating the battery and other electric stuff.
Another benefit is I will be able to make the wiring loom much shorter and simpler and will only have to lead a few wires to the back for brake/taillight and maybe some indicators.
I made a construction of some angular profile (40x40x3) because I just happened to have it laying around which gives a very rigid construction and easily forms a tray for the battery to fit in.
I'm using a 8Ah maintenance free battery which is a lot smaller than the standard 14Ah item.
I know the capacity is a lot less but it's standard on the RF900, Sam has been using it on his Evo2 GSX-R1100 and I have used it on mine for a year now so it's a proven solution for small spaces.
Dr.Bral has fitted the standard 14Ah battery, and that wasn't a problem too though the weight of it requires a sturdy construction and Dr. Bral admitted the 2mm aluminum plate he uses isn't quite up to the weight of the battery. I'm still in doubt of using a 4mm plate instead of the profiles because a plate will give me more space to play with to place the ignition, starter relays and fuse box.
