HI,

Sorry if this has been asked. I need to replace the bearings in two of my motors. NSR and NS. I measured the crank and both would appear to use the same front bearing. However the rear bearing I assume would be different because the NSR is 0.5mm larger (11.5mm) where the NS is (11mm). I'm not sure if all the NS and NSR range came with these spec cranks.

I have looked on the Novarrossi site at the expanded views and noticed that the part numbers for the bearing are the same. This doesn't seem right to me and I was hoping that someone could tell me if these are the right part numbers.

Front 17006
Rear 16602

Thank You
