I can't say I ever found it uncomfortable but feel the spacing of footrests and handlebars isn't quite right for me and either the footrests should be further back or handlebars higher so I've got 25mm SW Motech risers on mine and it made the bike feel a lot better for me.
Only problem was the original brake hose was stretched to its limit so got one made up an inch longer than standard. The cables and wiring had no problems.
You could probably go a bit higher if you wanted but might have to tilt the handlebars back a bit to avoid the levers hitting the fairing on full lock.
