Oh God shoot me now!
Ok here we go...the manual recommends 10W40 and you can use any name brand oil and you're fine.
If you want to go full synthetic that's up to you.....unless you do a lot of high speed riding I don't think it's necessary, today's regular dino oils are excellent quality.
I wouldn't use a "semi" synth as they don't tell you how much synthetic oil is in there...probably a 95% dino oil, waste of money.
I would use a "JASO MA" rated (on the back of the jug/bottle) oil as these oils have extra protection from the shearing that our trannies do to the oil and are designed for motorcycle engines.
I run CASTROL JASO MA rated Motorcycle oil, 10W40.
