Something like this will be very costly to transport.
The volume it takes up and the weight counts against it.
Just to give you an example, I sent a off-road bike from Cape Town up to JHB a few weeks ago, that was R2100 on economy
I reckon it will be cheaper to go and fetch it yourself on a double axle trailer.
Phone trailer rental companies. some times, if you are not on a tight schedule, they need to move a trailer from one town to another, And they will ask you basically just the one way trip. Maybe you are in luck.
