Synthetic engine oil can indeed cause clutch slip on wet clutch models, however the Motul being enquired about is specifically a transmission oil, and clearly states "...designed for gearboxes with integrated wet clutch using a different oil from engine oil".

We run and recommend Rock Oil GRO, and use it in everything from stock wet clutch NSR250s to the NSR500Vs.
