I googled the subject and found some Ducati Monster folk kicking around that topic: http://www.ducatimonster.org/smf/index.php/topic,13545.0.html

I guess it depends to some extent on how cold it is where you live...

Check the API quality level on your oil can. As long as your oil is good quality it should be OK. SV650 Manual quotes API SF or SG - these are older quality grades (second letter changes at each upgrade - we're now up to SM). Better quality will compensate for slightly thinner oil.

It shouldn't matter too much till the outdoor temps get a high (mid to high 20's in celcius)
