Hey Ollie, I don't have a 620 but I am pretty sure that the suspension is the same as my S2R800 ... well the same as it used to be. Knowing very little about these things I did a fair bit of reading on the forum, even a search for 'Suspension' in OzMonsters will dig up a few topics. Although it was after the fact here is a thread I started recently ... from memory it won't answer your questions but might be worth a read.
http://ducatimonsterforum.org/index.php?topic=28645.0As for your questions, based on my experience:
For the forks you have a couple of options:
. change oil and springs to suit your weight ... sounds like this is what you had in mind
. swap out your forks for something adjustable ... may require other work as a consequence
. cartridge kit ... you don't want to know which path I took
As for the rear, this is what I was told by my suspension guru:
. do the front first
. the rear is not worth upgrading
. save your bucks and just replace it when you have the funds
So I went the full monty on the back ... well the half monty really ... but changed out the whole shock. I don't know much about one model over the other and I didn't take the Ohlins route (hey I'm different ... and Ohlins on a Ducati, its kinda like owning a red one
) so can't offer much there. I think Cairns Duc upgrade to an Ohlins rear on his S2R but I think he stepped up one from the basic model ... he may be able to elaborate a bit more.
... and please don't bring up the exchange rate ...
