It's on the side of a baby bottle. Since I don't have one handy, I looked it up on internet. 1 us oz. = 29.57 cc so 6 X 29.57 = 177.42 Does that sound right? Maybe just get a baby bottle. :) JL

I run 170cc 5W in mine with 45mm preload. Then again i am 1) a fat ******* <_< 2) they are fitted to a B40 which is possibly a bit heavier than an OSSA However http://hem.passagen.se/ossa/ is a site that might be of help?

170cc works in my 199B also and they are Betor forks just the same as the OSSA but whatever. <_<

The Bulto forks take a bit less oil than the Ossa (maybe due to the shorter legs?)

Book recommends 200cc I think in MK1 or MK2 Ossa forks (as per bike pictured) I use 180cc generally with 10W as this gives a relatively soft action but as with most things it is all down to personal preference so you could use that as a starting point. The MK3 and onwards had longer forks so usually 200cc as a starting point for them.
