So, I've been riding with Motul oil that I changed 3 months ago and I must say I don't really like it...
The gearbox in particular became noticeably harsher, gear changes louder and harder.
Even my friend, who had Fazer 600 a few years ago said he once put Motul in and never again, due to same reasons.
Gonna switch to something else as soon as possible, probably Castrol.
