Ossa Tr77 Fork Oil

Can anyone please tell me the correct amount of oil per leg needed for the OSSA TR77 which has the long leg Betor forks. Presumably these are similar forks to those fitted to the OSSA MAR mk3?

Likewise the gearbox/clutch, amount & type.

    Forks try 180cc of 10W

    Gearbox takes 1 litre. Any modern gear oil such as Silkolene light. If you use heavier gearbox oil the clutch may not operate so well. I use Silkolene with Barnett plates, no issues.
