Fork oil?

[nodrog]

Can anybody tell me what the Motul or Spectro equivalent of Showa SS05 fork oil would be?

Showa SS05 is closer to 3.6wt than the designated 5wt

Spectro Ultra light 85/125 or Golden Spectro 125/150 are pretty close, the Ultra light is roughly 2.5wt & the Golden 125/150 roughly 5wt. The cSt value can vary over 20 points on the scale with 5wt oils.

In fact the centistoke rating is the only rating that is apples for apples. The SAE ratings used are a motor oil rating and are a total crock for suspension fluids.
