Sorted!!!! Couldnt believe it. Only found out 3 days ago that the XR tank is best fit for DR, albeit mountings to make.
Yesterday a virtually brand new one turned up on ebay.
So thats DR350SE with kick, RMZ suspension and large tank sorted.
As new pair of tubliss arrived last week.
The rest down to me.
Funny how things can drop into place, if you look hard enough.
