The 1991 DR350 wheels I bought for my 2001 DR-Z250 had the same issue.
The wheel bearings had the same OD but a smaller ID to match the axle. So the replacement wheel bearings I fitted were the same as the newer spec. Easy. Also I had to get an engineering shop to ream out (on a lathe) the bearing spacer in the old wheel to the larger diameter.
So all may not be lost!

- it's cool but it's still a BRP - so want full knobs for the trail ride stuff.

. Looking at specs confirms what I suspected - the XR is 128kg compared to 147 for DR650 and 119 for DRZ400E (the one I had). HP is 46 for the XR600, 43 for the DR650 and apparently 48 for the DRZ400 (but at 9000 rpm so who goes there?) In the real world it's the torque that makes the difference - 52Nm for the XR, 54Nm for the DR650 and only 40 for the DRZ400 but that's at 7500rpm compared with peak at 5500rpm for the XR and 4600rpm for the DR650.
