Sorry but I have another question on oil.
KTM specify semi-synthetic oil in the 390 Duke but fully synthetic in the 690 & 790 Dukes and 1190 Adventurer
Can anyone who knows about oil explain a reason for this? Is the 390 Duke engine design different or made out of materials that need semi-synthetic oil rather than fully synthetic?
If I used fully synthetic in a 390 Duke would I damage the engine?
Thanks
