Motul 5W40 4T - 7100 Engine Oil. 1x 5W40 4T - Motul 7100 Engine Oil. The 5W40 is a high quality fully synthetic low traction coefficient Ester based 4-stroke engine oil developed to provide high shear and temperature resistance at high revs for use in all performance motorcycles where a fully synthetic oil is specified.
Bought this for my K1300s service. Specification specifically mentions BMW approval where a 5w40 oil is specified. Considerably cheaper than the OEM provided oil, and so far engine feels nice and smooth and gearchange seems to have improved in terms of slickness and ease of change. I'd recommend this oil, and MOTUL products in general.
