I went into a NON Harley Davidson shop to buy oil and a oil filter, The shop had the correct oil filter on the Shelf and then asked me the age of the bike and if it was water cooled. Now being the good salesman he was sold me fully synthetic Shell Helix Ultra 10w = 40 technology motor oil for the 1125.
The question is yes / no to using fully synthetic oil
