Hey all! Just picked up a used Honda Metro NCW50 with just under 10,000 miles. I believe the scooter was really neglected and I am trying to cover all my bases.... I want to switch out the final drive / gear oil... I can't seem to find a straight answer for the type of oil to replace it with... I've read SAE 10W-30 but I've also seen 75w-90.... Not sure what to go with... I'd appreciate any help or guidance!! This is all still pretty new to me.. learning as I go! Thank you

 

HI, did you ever get a reply or figure this out? On Google nobody speaks of this. I just see the Ruckus forum members talking about their final drive. thanks!

 

I know this thread is way old, but I still can't find this info anywhere online so I broke down and bought the service manual. It's 10W-30. I think all the mentions I've seen of 75W-90 were for the Ruckus and people mistakenly thought the NCW50 Metro was the same.

RECOMMENDED FINAL DRIVE OIL:
Pro Honda HP4M (with molybdenum additives) 4-stroke oil (U.S.A. & Canada) or equivalent motorcycle oil
