I'm prepping the bike for this season and not sure if fully synthetic should be used because the bike is solely for racing and in a hot climate. What do I use? Sent from my iPhone using Tapatalk
I remember recently several posts that contain the information you are looking for, search for Opie Oils. IIRC the figures in the oil descriptor ie 10/40 refers to the oil viscocity at the temperature range so the higher the second figure the more suitable it is to higher ambient temperatures. You should be fine with a good quality fully synthetic 15/50. I use Motul 300v. Andy
I took advice from some locals ant bought 20W50 fully synth as that's what they use most here. Sent from my iPhone using Tapatalk
On wet clutch, with regular changes, better with semi synth as the plates can slip with hard use otherwise. But yours is dry so totally useless info :tearsofjoy:
I use Motul 300V 10w40 Double Ester Fully Synthetic oil in my 955SP. It's a groovy lime green colour. :sunglasses:
