HI All,
Not different at all to the SR in the engine department
If the auction was genuine I would presume the buyer is after the RGS identity more than anything else
If he then buys the frame he has the basis for a genuine RGS!!
There was a pair of RGS cases sold on ebay some weeks ago and the seller had the proof that they belonged to a genuine bike thet went for £871 ebay no. 130350347023.
They are numbered DA10R 7433,
Around the same time a set of cases DA10R 7426 made £260, ebay no.180439913671
Only being 7 numbers apart did the second buyer get something of a bargain???
Or maybe a couple of people had access to the factory records?

Cheers
John O R
