I'm a proud new owner of a Ryker 900 ACE as of Oct. 4th.
It has 200 km (124 miles) and it is time to put it away for the winter.
Must I change the oil?
My Service Manager who is 'tri syllabic' only offers the comment -:sour: "It is Recommended"
Seems a waste of clean oil to me, but I've no experience at all with motorbikes.
Any thoughts? Please and thank you.
