There are quite a few Raid owners on here and it would be good to use the collective knowledge to update the table of differences to put in the FAQ.
This is what I have so far and corrections, additions, suggestions welcomed!

The tank is larger on the Raid hence if you fill it right up its going to add weight over and above that of the OE
The headlight assembly on the Raid is more suitable for road or use on night trials but it is a fairly hefty (4lbs weight compared to 1lb 4oz of the OE plastic unit)item with a mild steel protection bar
The Raid has a lot of steel parts (swing arm, linkage arm and bottom shock yoke) whereas the OEs have these parts in aluminium
The rear axle bolt on the Raid is shorter than the OE’s so, if upgrading the Raid to an aluminium swing arm, the longer axle is needed.
The Raid doesn't have adjustable rear compression damping i.e. "Hard-Soft" clicker adjustment on the rear shock "reservoir whereas most OEs have them. The OE adjustable shock (yellow spring) will fit straight in.
There are no grease nipples on the Raid’s rear suspension linkages or swinging arm pivot so they need to be dismantled occasionally to prevent them from seizing up (same on Y2K models sadly).
The Raid’s side panels are more like “pods” - there is a useful plastic box under the left hand one containing the tool kit
Chain size and gearing is different with a 520 on the Open Enduro and a 428 on the Raid
The rear sub frame is also different as are the seat layouts – the Raid seat is lower (about 35” off the ground compared to the OE’s 36.25”) and flatter. It’s designed for more sat down, long distance work but is a lot better than the OE if you want to carry a passenger
Rear footpegs on the Raid are mounted separately onto the sub frame and on the Open Enduro are small alloy ones mounted direct to the subframe.
The rear grab handles on the Raid are quite a bit bigger than those on the OE.
Some Raids have a relay in the wiring loom that doesn’t switch the headlight on until the engine has started. An excellent idea!
Uber competitive the Japanese market, expect all or most of the extras you'd buy for a European market model to be fitted as standard.
If it's been modified from standard in Japan my experience of 400's and 250's says you can get some quite exotic 'extras'
