We in Australia do have plenty of unique and bread and butter VMX Solos and Sidecars, a lot are parked in garages and many more still waiting to by found and salvaged.
Why they remain out of sight is a huge mixture of reasons.
Like lots of people simply don't know what that "old piece of crap"is. Fair enough.
Some just as cruelly are wrapped in cotton wool and plastic film or in poxy static museums never to see to feel dirt under their tyres..
Age and health of owners.. we all know a decline in both is inevitable but we do love our toys from our younger days and stuff it !you got to keep your fond memories!,
Lack of time, finance or availability of parts to restore or repair machines,..... enough said!,
Machines hoarded for speculative purposes.... Hmmmmm....
Owners locking machines up in secret as they rightly scared of thieves and low life finding out about their prized bits and pieces.
Lack of meetings of all type in resonable traveling distances to display or race sell or swap your bikes and parts. Distance is a costly killer!
Closing and loss of tracks, riding areas....
Clubs and Controlling bodies > in fighting > not listening to us the paying members, lack of helpers to organise meetings or to PUSH FOR TOTAL ACCEPTANCE of our Sport/Pastime so we gets the public to come and view our treasures..
Lots and lots more reasons for sure! but lets don't think we are poor cousins to others .We have got to get what great treasure we have out for all to enjoy.
