Hello again. I need your help again. I have to change the oil. Which one of Motul or Motorex do you recomand ? Both 15 W 50 semi-sintetic.

Thank you in advance.

Suzuki recommends API SF or SG classified oils, over here in Germany not even the cheapest of oils go below theses standards.

In the following page from the German rider's handbook you can see which viscosity is recommended for which temperature range:


So any of those oils you mentioned is sufficient, use the one you like. But don't use car oils, they may have additives which interfere with the function of the clutch.

I would go for the cheapest oil as I've been doing over most of the 63.000 kilometres I've ridden my freewind by now.

Regards,
Dirk

A simply mineral 10W40 for a motobike will be enough and don`t buy the most expensive oil.
