Ya que habláis de Motul, hace poco mirando precios y cosillas por internet me encontré con esto en distintas web: (Los párrafos en negrita).
Motul 7100 4T Engine Oil
SAE 20W-50, fully synthetic
Motul 7100 4T 20W50 is a fully synthetic 4-stroke engine oil with ester technology. It exceeds the requirements
of motorcycle manufacturers such as Harley-Davidson, who approve a fully synthetic oil with 20W50 viscosity for certain models.
Properties:
- Excellent shear stability for reliable protection of engine and gearbox; permits smooth shifting
- Perfect wet clutch compatibility
- Standards: API SN/SM/SL/SJ/SH/SG
- Approvals: JASO MA2
Important note:
Motul 7100 4T 20W50 can be used for engine, gears and primary drive in Harley-Davidson Sportster Evolution models from 2006 onwards, V-Rod Revolution from 2002 onwards, and Twin Cam from 1999 onwards. In addition, for all Harley engines made by Buell.
IMPORTANT: If your engine has operated with mineral oils for longer than 5 years or more than 30,000 miles, we DO NOT recommend changing over to a fully synthetic oil! With the models listed above, this oil is perfectly compatible with gearboxes and primary drives, provided the previously used oil is removed completely and there is no mixing.
