ozscoot had them i think, but they closed down a long time ago, and carterraceengines probably had them, but they closed down too. i recommend you try viperformance in bayswater, Vic, but be careful, they are a little over priced...
and yes the r1's run on 12v scooter batteries like the ones found on ebay.
the r1 pull starts look like this:

the r1 coils look like this:

and the rims have a circumference of about 1000mm (1m).
hope this helps
