Mine appears to have a hollow rear, but I can't tell how big it is, and I don't have a rear stand yet so haven't taken off the wheel to actually measure it, although it looks smaller than the front.

you don't need to remove the wheel to see if it's the same size as the front. i KNOW your front axle's a 25mm. to find out if your rear is also the same size, use a ruler, tape measure, dial caliper and measure the inner diameter of the front and rear axles. you don't have to be super-accurate. if the rear's a 20mm unit, there'll be a significant enough difference in I/D that you'll tell easily.

IF!!! your rear IS in fact a 25mm axle (same diameter in front), then you should be able to fit ST4S rims or monster S4 rims on. your 1000 should have a 5.5" wheel in back which is the same width as the ST4S and monster S4's.
