Yep. cheers for the replies, I'd guessed the quote I used was flakey.
Somewhat annoyingly for Simon, just about every model DR650 seems to have a lowering kit available from Suzuki... except his.

Off to the steel stockist it is then (or rather, once again snaffle a suitable gauge offcut from a local fence welding firm).
Then he will have to strip his forks to see if they are the same as other model DR's that can be lowered by messing about with a spacer.
Of course he could just let some air out of his tyres
