Unbelievable, this is an Adventure Ride I could only dream of
I take my hat of to you and in future I will call you Sir Helgi.

Anyway, as promised the bearing parts you will need are :
F/wheel 2x 6004
R/wheel 2x 6204 & (1x 6322 for sprocket carrier)
Steering Top 1x 32005JS
Steering Bottom 1x 32006J
Remember you will need to re-use your existing seals.
I hope one day we will see you in Australia.
