I know most use Motul 10/40w with Ester.
My local shop sadly doesn't stock any Motul products though.



These seem to be my choices... none of which are very cheap :-(
all excellent points, it's easy to forget about the difference both in product availability and climate requirements for users in other countries.cybercarl wrote:Bare in mind this is in Oz IIRC Salty Dog is in Australia. So with their Hotter Winters and Summers the 15w 50 may suit better if one lives in the hotter parts of Oz. The Hotter climate would most likely thin it out to the equivalent of 10w 40
The Silkolene with the Yellow label would be my choice. I think this is a Semi synth as it don''t say Fully like the Red labelled Silkolene and it's cheaper which also suggests semi synth. Oil manufacturers are crap at labelling things in a simplified form.
You will also need a little more than 4l if changing the oil filter. These bike take a total of roughly 4.2l from empty to full.
