I rode a 675SS and 620ie Monster with clip-ons and rearsets back to back.
The SS benefitted from an Ohlins rear, measured fork oil and 60 profile front tyre while the Monster suspension was 2002 vintage, 4500 miles old and had a 70 profile front.
The riding position felt more natural on the SS (I'm only 5'8") but with a bit of work I reckon I could have got the Monster feeling the same. Mind you I'm not in Ali's league speed-wise
As for the new SS, it was interesting that Geoff's 620S had an old-shape tank.....
(PS I have a number of interestingly shaped tanks available following a productive year falling off)
