I changed the oil in my Yamaha Crypton S 115i.
The previous ones were Liqui Moli Street, semi-synthetic with a viscosity of 10w-40.
The Liqui performed as expected, although at first, for a few hundred km, I felt like the clutch discs were slipping and the gearbox was getting stuck during gear changes.
Afterwards, it improved, but the sticking still occurred, although not always.
As for the Motorex, first impressions are positive, with very good performance, smooth gear changes (like velvet), without any sticking in the gearbox.
I will come back with an updated comment.

Updated comment:
Excellent lubrication, very good performance, very good gearbox operation!!!
Although personally, I believe that it is a product of simple semi-synthetic oils, they do a very good job at a very good price!!!
The next choice will be from the same company, but the Formula 4T.
