Andy, unfortunately, it appears DSE no longer stocks the belt drive kit.
Until I was made aware of that kit, I tried a rubber band, but that only lasted a few weeks.
I've had a look at the Small Parts and Bearing belt section, but they don't appear to have small diameter round belts.http://www.smallparts.com.au/store/categories/belts/
Maybe a small "V" belt?
WES in Sydney have many belts for audio equipment: http://www.wagner.net.au/catalogue/05_Audio.pdf
(They have even more for VCRs, DVD players etc, in Section #4, but that they aren't referred to by size, simply the model number of the item it is intended for.)
Element14 don't appear to have anything suitable.
Jaycar have this kit http://www.jaycar.com.au/productView.asp?ID=HP0650
, but you would need to take a look and see if there is anything close.
I don't remember the belt diameter, but you are in the best position to measure this now.
Maybe a search on eBay.
On-line searches of hobby R/C stores.
Yes, you will need to undo some of the gears to slip the new belt over, but again, I don't remember any specifics.
It was over 5 years ago now, so it is worth going to the effort of finding a suitable belt that can be used.
You can keep on enjoying your KR-400RC... until something else goes wrong with it!
Can anyone else suggest likely sources of belts, as this will affect all round controller users, sooner or later?
