Hi guys new to trials and learning as I go, really getting into it all and loving the sport coming from an mtb back ground. I'm looking to change the oil on my sherco 250 it's recommended using 10w40 oil and 450ml to fill up with, just wondering what oil people recommend, also does it need to be light gear oil, fully synthetic and so on. Just looking to see what's best for the bike. Cheers again, I believe previous owner used rock oil light weight gear oil. Cheers, Brandon
